What are anterior cruciate ligament injuries?


One of the most common knee injuries is an anterior cruciate ligament sprain or tear.

The anterior cruciate ligament is one of the major stabilizing ligaments in the knee. It is a strong rope like structure located in the centre of the knee running from the femur to the tibia.

When this ligament tears unfortunately it doesn’t heal and often leads to the feeling of instability in the knee.

About half of all injuries to the anterior cruciate ligament occur along with damage to other structures in the knee, such as articular cartilage, meniscus, or other ligaments.

Injured ligaments are considered "sprains" and are graded on a severity scale.




How is the injury severity scale graded?


Grade 1 Sprains: The ligament is mildly damaged in a Grade 1 Sprain. It has been slightly stretched, but is still able to help keep the knee joint stable.

Grade 2 Sprains: A Grade 2 Sprain stretches the ligament to the point where it becomes loose. This is often referred to as a partial tear of the ligament.

Grade 3 Sprains: This type of sprain is most commonly referred to as a complete tear of the ligament. The ligament has been split into two pieces, and the knee joint is unstable.

Partial tears of the anterior cruciate ligament are rare; most ACL injuries are complete or near complete tears.




What are cruciate ligaments?


These are found inside your knee joint. They cross each other to form an "X" with the anterior cruciate ligament in front and the posterior cruciate ligament in back. The cruciate ligaments control the back and forth motion of your knee.

The anterior cruciate ligament runs diagonally in the middle of the knee. It prevents the tibia from sliding out in front of the femur, as well as provides rotational stability to the knee.




What causes cruciate ligament injuries?


The anterior cruciate ligament can be injured in several ways:

  • Changing direction rapidly
  • Stopping suddenly
  • Slowing down while running
  • Landing from a jump incorrectly
  • Direct contact or collision, such as a football tackle




What are the symptoms of anterior cruciate ligament injuries?


When you injure your anterior cruciate ligament, you might hear a "popping" noise and you may feel your knee give out from under you. Other typical symptoms include:

  • Pain with swelling: Within 24 hours, your knee will swell. If ignored, the swelling and pain may resolve on its own. However, if you attempt to return to sports, your knee will probably be unstable and you risk causing further damage to the cushioning cartilage (meniscus) of your knee.
  • Loss of full range of motion
  • Tenderness along the joint line
  • Discomfort while walking




How are ACL injuries diagnosed?


During your first visit, Dr Bhimani will talk to you about your symptoms and medical history.

During the physical examination, Dr Bhimani will check all the structures of your injured knee, and compare them to your non-injured knee. Most ligament injuries can be diagnosed with a thorough physical examination of the knee.

Imaging Tests

Other tests which may help Dr Bhimani confirm your diagnosis includes:

X-rays: Although they will not show any injury to your anterior cruciate ligament, x-rays can show whether the injury is associated with a broken bone.

Magnetic resonance imaging (MRI) scan: This study creates better images of soft tissues like the anterior cruciate ligament. However, an MRI is usually not required to make the diagnosis of a torn ACL.




How are ACL injuries treated?


Treatment for an ACL tear will vary depending upon the patient's individual needs. For example, the young athlete involved in agility sports will most likely require surgery to safely return to sports. The less active, usually older, individual may be able to return to a quieter lifestyle without surgery.




What are nonsurgical treatment options?


A torn ACL will not heal without surgery. But nonsurgical treatment may be effective for patients who are elderly or have a very low activity level. If the overall stability of the knee is intact, Dr Bhimani may recommend simple, nonsurgical options.

  • Bracing: Dr Bhimani may recommend a brace to protect your knee from instability. To further protect your knee, you may be given crutches to keep you from putting weight on your leg.
  • Physical therapy: As the swelling goes down, a careful rehabilitation program is started. Specific exercises will restore function to your knee and strengthen the leg muscles that support it.




What are surgical treatment options?


Rebuilding the ligament: Most ACL tears cannot be sutured (stitched) back together, so to surgically repair the ACL and restore knee stability the ligament must be reconstructed. Dr Bhimani will replace your torn ligament with a tissue graft. This graft acts as scaffolding for a new ligament to grow on.

Grafts can be obtained from several sources. Often they are taken from the patellar tendon, which runs between the kneecap and the shinbone. Hamstring tendons at the back of the thigh are a common source of grafts. Sometimes a quadriceps tendon, which runs from the kneecap into the thigh, is used. Finally, cadaver graft (allograft) can be used.

There are advantages and disadvantages to all graft sources. You should discuss graft choices with Dr Bhimani to help determine which is best for you.

Because the regrowth takes time, it may be six months or more before an athlete can return to sports after surgery.




How is the procedure done?


Surgery to rebuild an anterior cruciate ligament is done with an arthroscope using small incisions. Arthroscopic surgery is less invasive. The benefits of less invasive techniques include less pain from surgery, less time spent in the hospital, and quicker recovery times.




Is rehabilitation important with ACL injuries?


Whether your treatment involves surgery or not rehabilitation plays a vital role in getting you back to your daily activities. A physical therapy program will help you regain knee strength and motion.

If you have surgery, physical therapy first focuses on returning motion to the joint and surrounding muscles. This is followed by a strengthening program designed to protect the new ligament. This strengthening gradually increases the stress across the ligament. The final phase of rehabilitation is aimed at a functional return.

The remaining rehabilitation will be supervised by a physiotherapist and will involve activities such as exercise bike riding, swimming, proprioceptive exercises and muscle strengthening. Cycling can begin at 2 months, jogging can generally begin at around 3 months. The graft is strong enough to allow sport at around 6 months however other factors come into play such as confidence, fitness and adequate fitness and training.

Professional sportsmen often return at 6 months but recreational athletes may take 10 -12 months depending on motivation and time put into rehabilitation.

The rehabilitation and overall success of the procedure can be affected by associated injuries to the knee such as damage to meniscus, articular cartilage or other ligaments.

The following is a more detailed rehabilitation protocol useful for patients and physiotherapists. It is a guide only and must be adjusted on an individual basis taking into account pain, other pathology, work and other social factors.

Acute (0 – 2 Weeks)

Goals

  • Wound healing
  • Reduce swelling
  • Regain full extension
  • Full weight bearing
  • Wean off crutches
  • Promote muscle control

Treatment Guidelines

  • Pain and swelling reduction with ice, intermittent pressure pump, soft tissue massage and exercise
  • Patella mobilisation
  • Active range of motion knee exercises, calf and hamstring stretching, contraction (non-weight bearing progressing to standing), muscle control and full weight bearing. Aim for full extension by 2 weeks. Full flexion will take longer and generally will come with gradual stretching. Care needs to be taken with hamstring co contraction as this may result in hamstring strains if too vigorous. Light hamstring loading continues into the next stage with progression of general rehabilitation. Resisted hamstring loading should be avoided for approximately 6 weeks
  • Gait retraining encouraging extension at heel strike

Stage 2- Quadriceps Control (2-6 Weeks)

Goals

  • Full active range of motion
  • Normal gait with reasonable weight tolerance
  • Minimal pain and effusion
  • Develop muscular control for controlled pain free single leg lunge
  • Avoid hamstring strain
  • Develop early proprioceptive awareness

Treatment Guidelines

  • Use active, passive and hands on techniques to promote full range of motion
  • Progress closed chain exercises (quarter squats and single leg lunge) as pain allows. The emphasis is on pain free loading, VMO and gluteal activation
  • Introduce gym based exercise equipment including leg press and stationary cycle
  • Water based exercises can begin once the wound has healed, including treading water, gentle swimming avoiding breaststroke
  • Begin proprioceptive exercises including single standing leg balance on the ground and mini tramp. This can progress by introducing body movement whilst standing on one leg
  • Bilateral and single calf raises and stretching
  • Avoid isolated loading of the hamstrings due to ease of tear. Hamstrings will be progressively loaded through closed chain and gym based activity

Stage 3- Hamstring/Quadriceps Strengthening (6-12 Weeks)

Goals

  • Begin specific hamstring loading
  • Increase total leg strength
  • Promote good quadriceps control in lunge and hopping activity in preparation for running

Treatment Guidelines

  • Focal hamstring loading begins and is progressed steadily throughout the next stages of rehabilitation
  • Active prone knee flexion which can be quickly progressed to include a light weight and gradually increasing weights
  • Bilateral bridging off a chair. This can be progressed by moving onto a single leg bridge and then single leg bridge with weight held across the abdomen
  • Single straight leg dead lift initially active with increasing difficulty by adding dumbbells
  • With respect to hamstring loading, they should never be pushed into pain and should be carefully progressed. Any subtle strain or tightness following exercises should be managed with a reduction in hamstring based exercises
  • Gym based activity including leg presses, light squats and stationary bike which can be progressively increased in intensity as pain and control allow. It is important to monitor any effusions following exercise and if it is increasing then exercise should be toned down
  • Once single leg lunge control is comparable to the other side hopping can be introduced. Hops can be made more difficult by including variations such as forward/back, side to side off a step and in a quadrant
  • Running may begin towards the latter part of this stage
  • Prior to running certain criteria must be met
  • No anterior knee pain
  • A pain free lunge and hop that is comparable to the other side
  • The knee must have no effusion
  • Before jogging start having brisk walks, ideally on a treadmill to monitor landing
  • Action and any effusion. This should be done for several weeks before jogging properly
  • Increased proprioceptive manoeuvres with standing leg balance and progressive hopping based activity
  • Expand calf routine to include eccentric loading

Stage Four-Sport Specific (3-6 Months)

Goals

  • Improve leg strength
  • Develop running endurance speed, change of direction
  • Advanced proprioception
  • Prepare for return to sport and recreational lifestyle

Treatment Guidelines

  • Controlled sport specific activities should be included in the progression of running and gym loads. Increasing effusion post running that isn’t easily managed with ice should result in a reduction in running loads
  • Advanced proprioception to include controlled hopping and turning and balance correction
  • Monitor potential problems associated with increasing loads
  • No open chain resisted leg extension exercises unless authorised by your surgeon

Stage Five-Return to Sport (6 Months Plus)

Goals

  • A safe return to sporting activities

Treatment Guidelines

  • Full training for 1 month prior to active return to competitive sport
  • Preparation for body contact sports. Begin with low intensity one on one contests and progress by increasing intensity and complexity in preparation for drills that one might be expected to do at training
  • To improve running endurance leading up to a normal training session
Full range, no effusion, good quadriceps control for lunge, hopping and hop and turn type activity. Circumference measures of thigh and calf to within 1 cm of other side

Anaesthesia

What does post-operative care involve?


Avoiding Problems After Surgery Recognising the Signs of a Blood Clot Follow Dr Bhimani's instructions carefully to reduce the risk of blood clots developing during the first several weeks of your recovery. Notify Dr Bhimani immediately if you develop any of the following warning signs.​ The warning signs of possible blood clot in your leg include:

  • ​Pain in your calf and leg that is unrelated to your incision
  • Tenderness or redness of your calf
  • New or increasing swelling of your thigh, calf, ankle, or foot
The warning signs that a blood clot has traveled to your lung include:
  • Sudden shortness of breath
  • Sudden onset of chest pain
  • Localized chest pain with coughing
Preventing Infection A common cause of infection following surgery is from bacteria that enter the bloodstream during dental procedures, urinary tract infections, or skin infections. Following surgery, patients with certain risk factors may need to take antibiotics prior to dental work, including dental cleanings, or before any surgical procedure that could allow bacteria to enter your bloodstream. Dr Bhimani will discuss with you whether taking preventive antibiotics before dental procedures is needed in your situation. Notify your doctor immediately if you develop any of the following signs of a possible infection:
  • Persistent fever (higher than 100°F orally)
  • Shaking chills
  • Increasing redness, tenderness, or swelling of the wound
  • Drainage from the wound
  • Increasing pain with both activity and rest
Avoiding Falls A fall during the first few weeks after surgery can damage your new hip or knee and may result in a need for more surgery. Stairs are a particular hazard until your hip is strong and mobile. You should use a cane, crutches, a walker, or handrails or have someone help you until you improve your balance, flexibility, and strength. Dr Bhimani and physical therapist will help you decide which assistive aides will be required following surgery, and when those aides can safely be discontinued. Other Precautions To assure proper recovery and prevent dislocation of the prosthesis, you may be asked to take special precautions when sitting, bending, or sleeping — usually for the first 6 weeks after surgery. These precautions will vary from patient to patient. Prior to discharge from the hospital, Dr Bhimani and your physical therapist will provide you with any specific precautions you should follow. Recovery The success of your surgery will depend in large measure on how well you follow Dr Bhimani's instructions regarding home care during the first few weeks after surgery. Wound Care You may have stitches or staples running along your wound or a suture beneath your skin. The stitches or staples will be removed approximately 2 weeks after surgery. Avoid getting the wound wet until it has thoroughly sealed and dried. You may continue to bandage the wound to prevent irritation from clothing or support stockings. Diet Some loss of appetite is common for several weeks after surgery. A balanced diet, often with an iron supplement, is important to promote proper tissue healing and restore muscle strength. Be sure to drink plenty of fluids. Activity Exercise is a critical component of home care, particularly during the first few weeks after surgery. You should be able to resume most normal light activities of daily living within 3 to 6 weeks following surgery. Some discomfort with activity and at night is common for several weeks. Your activity program should include:
  • A graduated walking program to slowly increase your mobility, initially in your home and later outside.
  • Resuming other normal household activities, such as sitting, standing, and climbing stairs.
  • Specific exercises several times a day to restore movement and strengthen your hip. You probably will be able to perform the exercises without help, but you may have a physical therapist help you at home or in a therapy centre the first few weeks after surgery.
If you have any questions please contact Dr Bhimani via 02 4229 9116.

What are anterior cruciate ligament injuries?


One of the most common knee injuries is an anterior cruciate ligament sprain or tear.

The anterior cruciate ligament is one of the major stabilizing ligaments in the knee. It is a strong rope like structure located in the centre of the knee running from the femur to the tibia.

When this ligament tears unfortunately it doesn’t heal and often leads to the feeling of instability in the knee.

About half of all injuries to the anterior cruciate ligament occur along with damage to other structures in the knee, such as articular cartilage, meniscus, or other ligaments.

Injured ligaments are considered "sprains" and are graded on a severity scale.




How is the injury severity scale graded?


Grade 1 Sprains: The ligament is mildly damaged in a Grade 1 Sprain. It has been slightly stretched, but is still able to help keep the knee joint stable.

Grade 2 Sprains: A Grade 2 Sprain stretches the ligament to the point where it becomes loose. This is often referred to as a partial tear of the ligament.

Grade 3 Sprains: This type of sprain is most commonly referred to as a complete tear of the ligament. The ligament has been split into two pieces, and the knee joint is unstable.

Partial tears of the anterior cruciate ligament are rare; most ACL injuries are complete or near complete tears.




What are cruciate ligaments?


These are found inside your knee joint. They cross each other to form an "X" with the anterior cruciate ligament in front and the posterior cruciate ligament in back. The cruciate ligaments control the back and forth motion of your knee.

The anterior cruciate ligament runs diagonally in the middle of the knee. It prevents the tibia from sliding out in front of the femur, as well as provides rotational stability to the knee.




What causes cruciate ligament injuries?


The anterior cruciate ligament can be injured in several ways:

  • Changing direction rapidly
  • Stopping suddenly
  • Slowing down while running
  • Landing from a jump incorrectly
  • Direct contact or collision, such as a football tackle




What are the symptoms of anterior cruciate ligament injuries?


When you injure your anterior cruciate ligament, you might hear a "popping" noise and you may feel your knee give out from under you. Other typical symptoms include:

  • Pain with swelling: Within 24 hours, your knee will swell. If ignored, the swelling and pain may resolve on its own. However, if you attempt to return to sports, your knee will probably be unstable and you risk causing further damage to the cushioning cartilage (meniscus) of your knee.
  • Loss of full range of motion
  • Tenderness along the joint line
  • Discomfort while walking




How are ACL injuries diagnosed?


During your first visit, Dr Bhimani will talk to you about your symptoms and medical history.

During the physical examination, Dr Bhimani will check all the structures of your injured knee, and compare them to your non-injured knee. Most ligament injuries can be diagnosed with a thorough physical examination of the knee.

Imaging Tests

Other tests which may help Dr Bhimani confirm your diagnosis includes:

X-rays: Although they will not show any injury to your anterior cruciate ligament, x-rays can show whether the injury is associated with a broken bone.

Magnetic resonance imaging (MRI) scan: This study creates better images of soft tissues like the anterior cruciate ligament. However, an MRI is usually not required to make the diagnosis of a torn ACL.




How are ACL injuries treated?


Treatment for an ACL tear will vary depending upon the patient's individual needs. For example, the young athlete involved in agility sports will most likely require surgery to safely return to sports. The less active, usually older, individual may be able to return to a quieter lifestyle without surgery.




What are nonsurgical treatment options?


A torn ACL will not heal without surgery. But nonsurgical treatment may be effective for patients who are elderly or have a very low activity level. If the overall stability of the knee is intact, Dr Bhimani may recommend simple, nonsurgical options.

  • Bracing: Dr Bhimani may recommend a brace to protect your knee from instability. To further protect your knee, you may be given crutches to keep you from putting weight on your leg.
  • Physical therapy: As the swelling goes down, a careful rehabilitation program is started. Specific exercises will restore function to your knee and strengthen the leg muscles that support it.




What are surgical treatment options?


Rebuilding the ligament: Most ACL tears cannot be sutured (stitched) back together, so to surgically repair the ACL and restore knee stability the ligament must be reconstructed. Dr Bhimani will replace your torn ligament with a tissue graft. This graft acts as scaffolding for a new ligament to grow on.

Grafts can be obtained from several sources. Often they are taken from the patellar tendon, which runs between the kneecap and the shinbone. Hamstring tendons at the back of the thigh are a common source of grafts. Sometimes a quadriceps tendon, which runs from the kneecap into the thigh, is used. Finally, cadaver graft (allograft) can be used.

There are advantages and disadvantages to all graft sources. You should discuss graft choices with Dr Bhimani to help determine which is best for you.

Because the regrowth takes time, it may be six months or more before an athlete can return to sports after surgery.




How is the procedure done?


Surgery to rebuild an anterior cruciate ligament is done with an arthroscope using small incisions. Arthroscopic surgery is less invasive. The benefits of less invasive techniques include less pain from surgery, less time spent in the hospital, and quicker recovery times.




Is rehabilitation important with ACL injuries?


Whether your treatment involves surgery or not rehabilitation plays a vital role in getting you back to your daily activities. A physical therapy program will help you regain knee strength and motion.

If you have surgery, physical therapy first focuses on returning motion to the joint and surrounding muscles. This is followed by a strengthening program designed to protect the new ligament. This strengthening gradually increases the stress across the ligament. The final phase of rehabilitation is aimed at a functional return.

The remaining rehabilitation will be supervised by a physiotherapist and will involve activities such as exercise bike riding, swimming, proprioceptive exercises and muscle strengthening. Cycling can begin at 2 months, jogging can generally begin at around 3 months. The graft is strong enough to allow sport at around 6 months however other factors come into play such as confidence, fitness and adequate fitness and training.

Professional sportsmen often return at 6 months but recreational athletes may take 10 -12 months depending on motivation and time put into rehabilitation.

The rehabilitation and overall success of the procedure can be affected by associated injuries to the knee such as damage to meniscus, articular cartilage or other ligaments.

The following is a more detailed rehabilitation protocol useful for patients and physiotherapists. It is a guide only and must be adjusted on an individual basis taking into account pain, other pathology, work and other social factors.

Acute (0 – 2 Weeks)

Goals

  • Wound healing
  • Reduce swelling
  • Regain full extension
  • Full weight bearing
  • Wean off crutches
  • Promote muscle control

Treatment Guidelines

  • Pain and swelling reduction with ice, intermittent pressure pump, soft tissue massage and exercise
  • Patella mobilisation
  • Active range of motion knee exercises, calf and hamstring stretching, contraction (non-weight bearing progressing to standing), muscle control and full weight bearing. Aim for full extension by 2 weeks. Full flexion will take longer and generally will come with gradual stretching. Care needs to be taken with hamstring co contraction as this may result in hamstring strains if too vigorous. Light hamstring loading continues into the next stage with progression of general rehabilitation. Resisted hamstring loading should be avoided for approximately 6 weeks
  • Gait retraining encouraging extension at heel strike

Stage 2- Quadriceps Control (2-6 Weeks)

Goals

  • Full active range of motion
  • Normal gait with reasonable weight tolerance
  • Minimal pain and effusion
  • Develop muscular control for controlled pain free single leg lunge
  • Avoid hamstring strain
  • Develop early proprioceptive awareness

Treatment Guidelines

  • Use active, passive and hands on techniques to promote full range of motion
  • Progress closed chain exercises (quarter squats and single leg lunge) as pain allows. The emphasis is on pain free loading, VMO and gluteal activation
  • Introduce gym based exercise equipment including leg press and stationary cycle
  • Water based exercises can begin once the wound has healed, including treading water, gentle swimming avoiding breaststroke
  • Begin proprioceptive exercises including single standing leg balance on the ground and mini tramp. This can progress by introducing body movement whilst standing on one leg
  • Bilateral and single calf raises and stretching
  • Avoid isolated loading of the hamstrings due to ease of tear. Hamstrings will be progressively loaded through closed chain and gym based activity

Stage 3- Hamstring/Quadriceps Strengthening (6-12 Weeks)

Goals

  • Begin specific hamstring loading
  • Increase total leg strength
  • Promote good quadriceps control in lunge and hopping activity in preparation for running

Treatment Guidelines

  • Focal hamstring loading begins and is progressed steadily throughout the next stages of rehabilitation
  • Active prone knee flexion which can be quickly progressed to include a light weight and gradually increasing weights
  • Bilateral bridging off a chair. This can be progressed by moving onto a single leg bridge and then single leg bridge with weight held across the abdomen
  • Single straight leg dead lift initially active with increasing difficulty by adding dumbbells
  • With respect to hamstring loading, they should never be pushed into pain and should be carefully progressed. Any subtle strain or tightness following exercises should be managed with a reduction in hamstring based exercises
  • Gym based activity including leg presses, light squats and stationary bike which can be progressively increased in intensity as pain and control allow. It is important to monitor any effusions following exercise and if it is increasing then exercise should be toned down
  • Once single leg lunge control is comparable to the other side hopping can be introduced. Hops can be made more difficult by including variations such as forward/back, side to side off a step and in a quadrant
  • Running may begin towards the latter part of this stage
  • Prior to running certain criteria must be met
  • No anterior knee pain
  • A pain free lunge and hop that is comparable to the other side
  • The knee must have no effusion
  • Before jogging start having brisk walks, ideally on a treadmill to monitor landing
  • Action and any effusion. This should be done for several weeks before jogging properly
  • Increased proprioceptive manoeuvres with standing leg balance and progressive hopping based activity
  • Expand calf routine to include eccentric loading

Stage Four-Sport Specific (3-6 Months)

Goals

  • Improve leg strength
  • Develop running endurance speed, change of direction
  • Advanced proprioception
  • Prepare for return to sport and recreational lifestyle

Treatment Guidelines

  • Controlled sport specific activities should be included in the progression of running and gym loads. Increasing effusion post running that isn’t easily managed with ice should result in a reduction in running loads
  • Advanced proprioception to include controlled hopping and turning and balance correction
  • Monitor potential problems associated with increasing loads
  • No open chain resisted leg extension exercises unless authorised by your surgeon

Stage Five-Return to Sport (6 Months Plus)

Goals

  • A safe return to sporting activities

Treatment Guidelines

  • Full training for 1 month prior to active return to competitive sport
  • Preparation for body contact sports. Begin with low intensity one on one contests and progress by increasing intensity and complexity in preparation for drills that one might be expected to do at training
  • To improve running endurance leading up to a normal training session
Full range, no effusion, good quadriceps control for lunge, hopping and hop and turn type activity. Circumference measures of thigh and calf to within 1 cm of other side





 

Arthroscopic Surgery

What does post-operative care involve?


Avoiding Problems After Surgery Recognising the Signs of a Blood Clot Follow Dr Bhimani's instructions carefully to reduce the risk of blood clots developing during the first several weeks of your recovery. Notify Dr Bhimani immediately if you develop any of the following warning signs.​ The warning signs of possible blood clot in your leg include:

  • ​Pain in your calf and leg that is unrelated to your incision
  • Tenderness or redness of your calf
  • New or increasing swelling of your thigh, calf, ankle, or foot
The warning signs that a blood clot has traveled to your lung include:
  • Sudden shortness of breath
  • Sudden onset of chest pain
  • Localized chest pain with coughing
Preventing Infection A common cause of infection following surgery is from bacteria that enter the bloodstream during dental procedures, urinary tract infections, or skin infections. Following surgery, patients with certain risk factors may need to take antibiotics prior to dental work, including dental cleanings, or before any surgical procedure that could allow bacteria to enter your bloodstream. Dr Bhimani will discuss with you whether taking preventive antibiotics before dental procedures is needed in your situation. Notify your doctor immediately if you develop any of the following signs of a possible infection:
  • Persistent fever (higher than 100°F orally)
  • Shaking chills
  • Increasing redness, tenderness, or swelling of the wound
  • Drainage from the wound
  • Increasing pain with both activity and rest
Avoiding Falls A fall during the first few weeks after surgery can damage your new hip or knee and may result in a need for more surgery. Stairs are a particular hazard until your hip is strong and mobile. You should use a cane, crutches, a walker, or handrails or have someone help you until you improve your balance, flexibility, and strength. Dr Bhimani and physical therapist will help you decide which assistive aides will be required following surgery, and when those aides can safely be discontinued. Other Precautions To assure proper recovery and prevent dislocation of the prosthesis, you may be asked to take special precautions when sitting, bending, or sleeping — usually for the first 6 weeks after surgery. These precautions will vary from patient to patient. Prior to discharge from the hospital, Dr Bhimani and your physical therapist will provide you with any specific precautions you should follow. Recovery The success of your surgery will depend in large measure on how well you follow Dr Bhimani's instructions regarding home care during the first few weeks after surgery. Wound Care You may have stitches or staples running along your wound or a suture beneath your skin. The stitches or staples will be removed approximately 2 weeks after surgery. Avoid getting the wound wet until it has thoroughly sealed and dried. You may continue to bandage the wound to prevent irritation from clothing or support stockings. Diet Some loss of appetite is common for several weeks after surgery. A balanced diet, often with an iron supplement, is important to promote proper tissue healing and restore muscle strength. Be sure to drink plenty of fluids. Activity Exercise is a critical component of home care, particularly during the first few weeks after surgery. You should be able to resume most normal light activities of daily living within 3 to 6 weeks following surgery. Some discomfort with activity and at night is common for several weeks. Your activity program should include:
  • A graduated walking program to slowly increase your mobility, initially in your home and later outside.
  • Resuming other normal household activities, such as sitting, standing, and climbing stairs.
  • Specific exercises several times a day to restore movement and strengthen your hip. You probably will be able to perform the exercises without help, but you may have a physical therapist help you at home or in a therapy centre the first few weeks after surgery.
If you have any questions please contact Dr Bhimani via 02 4229 9116.





 

Anterior Cruciate Ligament (ACL) Injuries

What are anterior cruciate ligament injuries?


One of the most common knee injuries is an anterior cruciate ligament sprain or tear.

The anterior cruciate ligament is one of the major stabilizing ligaments in the knee. It is a strong rope like structure located in the centre of the knee running from the femur to the tibia.

When this ligament tears unfortunately it doesn’t heal and often leads to the feeling of instability in the knee.

About half of all injuries to the anterior cruciate ligament occur along with damage to other structures in the knee, such as articular cartilage, meniscus, or other ligaments.

Injured ligaments are considered "sprains" and are graded on a severity scale.




How is the injury severity scale graded?


Grade 1 Sprains: The ligament is mildly damaged in a Grade 1 Sprain. It has been slightly stretched, but is still able to help keep the knee joint stable.

Grade 2 Sprains: A Grade 2 Sprain stretches the ligament to the point where it becomes loose. This is often referred to as a partial tear of the ligament.

Grade 3 Sprains: This type of sprain is most commonly referred to as a complete tear of the ligament. The ligament has been split into two pieces, and the knee joint is unstable.

Surgery to rebuild an anterior cruciate ligament is done with an arthroscope using small incisions. Arthroscopic surgery is less invasive. The benefits of less invasive techniques include less pain from surgery, less time spent in the hospital, and quicker recovery times.




Is rehabilitation important with ACL injuries?


Whether your treatment involves surgery or not rehabilitation plays a vital role in getting you back to your daily activities. A physical therapy program will help you regain knee strength and motion.

If you have surgery, physical therapy first focuses on returning motion to the joint and surrounding muscles. This is followed by a strengthening program designed to protect the new ligament. This strengthening gradually increases the stress across the ligament. The final phase of rehabilitation is aimed at a functional return.

The remaining rehabilitation will be supervised by a physiotherapist and will involve activities such as exercise bike riding, swimming, proprioceptive exercises and muscle strengthening. Cycling can begin at 2 months, jogging can generally begin at around 3 months. The graft is strong enough to allow sport at around 6 months however other factors come into play such as confidence, fitness and adequate fitness and training.

Professional sportsmen often return at 6 months but recreational athletes may take 10 -12 months depending on motivation and time put into rehabilitation.

The rehabilitation and overall success of the procedure can be affected by associated injuries to the knee such as damage to meniscus, articular cartilage or other ligaments.

The following is a more detailed rehabilitation protocol useful for patients and physiotherapists. It is a guide only and must be adjusted on an individual basis taking into account pain, other pathology, work and other social factors.

Acute (0 – 2 Weeks)

Goals

  • Wound healing
  • Reduce swelling
  • Regain full extension
  • Full weight bearing
  • Wean off crutches
  • Promote muscle control

Treatment Guidelines

  • Pain and swelling reduction with ice, intermittent pressure pump, soft tissue massage and exercise
  • Patella mobilisation
  • Active range of motion knee exercises, calf and hamstring stretching, contraction (non-weight bearing progressing to standing), muscle control and full weight bearing. Aim for full extension by 2 weeks. Full flexion will take longer and generally will come with gradual stretching. Care needs to be taken with hamstring co contraction as this may result in hamstring strains if too vigorous. Light hamstring loading continues into the next stage with progression of general rehabilitation. Resisted hamstring loading should be avoided for approximately 6 weeks
  • Gait retraining encouraging extension at heel strike

Stage 2- Quadriceps Control (2-6 Weeks)

Goals

  • Full active range of motion
  • Normal gait with reasonable weight tolerance
  • Minimal pain and effusion
  • Develop muscular control for controlled pain free single leg lunge
  • Avoid hamstring strain
  • Develop early proprioceptive awareness

Treatment Guidelines

  • Use active, passive and hands on techniques to promote full range of motion
  • Progress closed chain exercises (quarter squats and single leg lunge) as pain allows. The emphasis is on pain free loading, VMO and gluteal activation
  • Introduce gym based exercise equipment including leg press and stationary cycle
  • Water based exercises can begin once the wound has healed, including treading water, gentle swimming avoiding breaststroke
  • Begin proprioceptive exercises including single standing leg balance on the ground and mini tramp. This can progress by introducing body movement whilst standing on one leg
  • Bilateral and single calf raises and stretching
  • Avoid isolated loading of the hamstrings due to ease of tear. Hamstrings will be progressively loaded through closed chain and gym based activity

Stage 3- Hamstring/Quadriceps Strengthening (6-12 Weeks)

Goals

  • Begin specific hamstring loading
  • Increase total leg strength
  • Promote good quadriceps control in lunge and hopping activity in preparation for running

Treatment Guidelines

  • Focal hamstring loading begins and is progressed steadily throughout the next stages of rehabilitation
  • Active prone knee flexion which can be quickly progressed to include a light weight and gradually increasing weights
  • Bilateral bridging off a chair. This can be progressed by moving onto a single leg bridge and then single leg bridge with weight held across the abdomen
  • Single straight leg dead lift initially active with increasing difficulty by adding dumbbells
  • With respect to hamstring loading, they should never be pushed into pain and should be carefully progressed. Any subtle strain or tightness following exercises should be managed with a reduction in hamstring based exercises
  • Gym based activity including leg presses, light squats and stationary bike which can be progressively increased in intensity as pain and control allow. It is important to monitor any effusions following exercise and if it is increasing then exercise should be toned down
  • Once single leg lunge control is comparable to the other side hopping can be introduced. Hops can be made more difficult by including variations such as forward/back, side to side off a step and in a quadrant
  • Running may begin towards the latter part of this stage
  • Prior to running certain criteria must be met
  • No anterior knee pain
  • A pain free lunge and hop that is comparable to the other side
  • The knee must have no effusion
  • Before jogging start having brisk walks, ideally on a treadmill to monitor landing
  • Action and any effusion. This should be done for several weeks before jogging properly
  • Increased proprioceptive manoeuvres with standing leg balance and progressive hopping based activity
  • Expand calf routine to include eccentric loading

Stage Four-Sport Specific (3-6 Months)

Goals

  • Improve leg strength
  • Develop running endurance speed, change of direction
  • Advanced proprioception
  • Prepare for return to sport and recreational lifestyle

Treatment Guidelines

  • Controlled sport specific activities should be included in the progression of running and gym loads. Increasing effusion post running that isn’t easily managed with ice should result in a reduction in running loads
  • Advanced proprioception to include controlled hopping and turning and balance correction
  • Monitor potential problems associated with increasing loads
  • No open chain resisted leg extension exercises unless authorised by your surgeon

Stage Five-Return to Sport (6 Months Plus)

Goals

  • A safe return to sporting activities

Treatment Guidelines

  • Full training for 1 month prior to active return to competitive sport
  • Preparation for body contact sports. Begin with low intensity one on one contests and progress by increasing intensity and complexity in preparation for drills that one might be expected to do at training
  • To improve running endurance leading up to a normal training session
Full range, no effusion, good quadriceps control for lunge, hopping and hop and turn type activity. Circumference measures of thigh and calf to within 1 cm of other side

What does post-operative care involve?


Avoiding Problems After Surgery Recognising the Signs of a Blood Clot Follow Dr Bhimani's instructions carefully to reduce the risk of blood clots developing during the first several weeks of your recovery. Notify Dr Bhimani immediately if you develop any of the following warning signs.​ The warning signs of possible blood clot in your leg include:

  • ​Pain in your calf and leg that is unrelated to your incision
  • Tenderness or redness of your calf
  • New or increasing swelling of your thigh, calf, ankle, or foot
The warning signs that a blood clot has traveled to your lung include:
  • Sudden shortness of breath
  • Sudden onset of chest pain
  • Localized chest pain with coughing
Preventing Infection A common cause of infection following surgery is from bacteria that enter the bloodstream during dental procedures, urinary tract infections, or skin infections. Following surgery, patients with certain risk factors may need to take antibiotics prior to dental work, including dental cleanings, or before any surgical procedure that could allow bacteria to enter your bloodstream. Dr Bhimani will discuss with you whether taking preventive antibiotics before dental procedures is needed in your situation. Notify your doctor immediately if you develop any of the following signs of a possible infection:
  • Persistent fever (higher than 100°F orally)
  • Shaking chills
  • Increasing redness, tenderness, or swelling of the wound
  • Drainage from the wound
  • Increasing pain with both activity and rest
Avoiding Falls A fall during the first few weeks after surgery can damage your new hip or knee and may result in a need for more surgery. Stairs are a particular hazard until your hip is strong and mobile. You should use a cane, crutches, a walker, or handrails or have someone help you until you improve your balance, flexibility, and strength. Dr Bhimani and physical therapist will help you decide which assistive aides will be required following surgery, and when those aides can safely be discontinued. Other Precautions To assure proper recovery and prevent dislocation of the prosthesis, you may be asked to take special precautions when sitting, bending, or sleeping — usually for the first 6 weeks after surgery. These precautions will vary from patient to patient. Prior to discharge from the hospital, Dr Bhimani and your physical therapist will provide you with any specific precautions you should follow. Recovery The success of your surgery will depend in large measure on how well you follow Dr Bhimani's instructions regarding home care during the first few weeks after surgery. Wound Care You may have stitches or staples running along your wound or a suture beneath your skin. The stitches or staples will be removed approximately 2 weeks after surgery. Avoid getting the wound wet until it has thoroughly sealed and dried. You may continue to bandage the wound to prevent irritation from clothing or support stockings. Diet Some loss of appetite is common for several weeks after surgery. A balanced diet, often with an iron supplement, is important to promote proper tissue healing and restore muscle strength. Be sure to drink plenty of fluids. Activity Exercise is a critical component of home care, particularly during the first few weeks after surgery. You should be able to resume most normal light activities of daily living within 3 to 6 weeks following surgery. Some discomfort with activity and at night is common for several weeks. Your activity program should include:
  • A graduated walking program to slowly increase your mobility, initially in your home and later outside.
  • Resuming other normal household activities, such as sitting, standing, and climbing stairs.
  • Specific exercises several times a day to restore movement and strengthen your hip. You probably will be able to perform the exercises without help, but you may have a physical therapist help you at home or in a therapy centre the first few weeks after surgery.
If you have any questions please contact Dr Bhimani via 02 4229 9116.
