Anterior cruciate ligament (ACL) rupture and anterolateral ligament (ALL) rupture

•

Possible treatments for an ACL or ALL rupture

Possible treatments following an anterior cruciate ligament rupture

 

When a person sustains an anterior cruciate ligament (ACL) rupture, several treatment options may be considered, depending on various factors such as the patient’s age, activity level, the severity of the injury, and functional goals. Below is an overview of the main possible treatments for an ACL rupture.

Possible treatments following an anterolateral ligament (ALL) rupture

 

Management of an anterolateral ligament (ALL) rupture of the knee depends on various factors, including the severity of the injury, the patient’s functional goals, and the possible presence of associated injuries such as those of the anterior cruciate ligament (ACL).

Non-surgical treatments

Anterior cruciate ligament

 

Rehabilitation and muscle strengthening

– Physical rehabilitation is often recommended to strengthen the muscles around the knee, particularly the quadriceps and hamstrings, to stabilize the joint and partially compensate for the absence of the ACL.
– The exercises also aim to improve knee mobility, balance, and proprioception.

Support brace

– The use of a knee brace may be recommended to provide additional support and help prevent excessive movement, particularly when resuming daily or sports activities.

Pain and inflammation management

– Anti-inflammatory medications and analgesics may be prescribed to relieve pain and reduce inflammation in the knee.

Anterolateral ligament

 

Functional rehabilitation

Physiotherapy : A structured rehabilitation program can help strengthen the muscles around the knee, particularly the quadriceps and hamstrings, to compensate for the loss of stability.

Proprioception exercises : Exercises aimed at improving balance and coordination are essential to stabilize the joint.

Use of braces or knee supports :

A brace or knee support may be used to stabilize the knee during physical activities and reduce the risk of excessive movement or twisting.

Pain and inflammation management :

Non-steroidal anti-inflammatory drugs (NSAIDs) and analgesics may be prescribed to manage pain and reduce inflammation.

Surgical treatments

Anterior cruciate ligament: arthroscopic ACL reconstruction

 

Cruciate ligament reconstruction is a surgical procedure aimed at reconstructing a torn cruciate ligament in the knee.
This procedure is often performed when the anterior cruciate ligament (ACL) is damaged, although the posterior cruciate ligament (PCL) can also be repaired in this way.
Below is a detailed explanation of what ACL reconstruction involves:

Purpose of ACL reconstruction

The purpose of reconstruction is to restore knee stability by replacing the torn ligament with a graft.
This enables the patient to regain normal knee function, resume daily activities and, often, sports activities.

Indications for reconstruction

– Complete ACL rupture with significant knee instability.
– Failure of conservative (non-surgical) treatment to relieve symptoms.
– Young, active patients wishing to return to sports or activities requiring knee stability.
– Presence of associated meniscal or cartilage injuries requiring surgery.
– Types of grafts used
– Autograft: harvesting a tendon from the patient to reconstruct the ACL. Common options include:

– Patellar tendon.

– Hamstring tendons (semitendinosus and gracilis).

– Quadriceps tendon.

– Allograft: use of a tendon from a human donor.

– This is an option for patients who prefer to avoid harvesting a tendon from their own body.

 

Procedure steps

Patient preparation:

The patient is placed under general or spinal anesthesia.
The knee is cleaned and prepared for surgery.
Arthroscopic access:

Small incisions are made around the knee to insert an arthroscope (camera) and surgical instruments.

Assessment and preparation:

The surgeon assesses the inside of the joint to confirm the ACL rupture and identify other injuries.
The remnants of the damaged ACL are removed, and the insertion sites on the femur and tibia are prepared.
Graft harvesting:

If an autograft is used, the graft is harvested from the selected tendon.
If an allograft is used, the graft is prepared from donor tissue.
Creation of bone tunnels:

Tunnels are drilled in the femur and tibia to allow passage and fixation of the graft.
Insertion and fixation of the graft:

The graft is passed through the bone tunnels and fixed using fixation devices such as screws, staples, or buttons.
Stability check:

The surgeon checks the tension and position of the graft to ensure it is properly fixed and that the knee is stable.
Closure of incisions:

The incisions are closed using sutures or adhesive dressings.
Postoperative rehabilitation

Initial phase:

Rest and protection of the knee with the use of crutches and a brace.
Pain and swelling management with medication, ice, and elevation.

Rehabilitation:

Physiotherapy program to restore mobility, strengthen muscles, and improve proprioception.
Progressive exercises to increase flexibility and strength.
Gradual return to activities:

Rehabilitation continues over several months, with a gradual return to normal and sports activities under the supervision of the physiotherapist.
Expected outcomes
Restoration of knee stability.
Improved function and mobility.
Reduced pain and inflammation.
Return to sports activities for most patients.

Cruciate ligament reconstruction is an effective surgical procedure for treating ACL ruptures. With appropriate rehabilitation, most patients can expect to regain good knee stability and function, enabling them to resume their daily and sports activities.

 

Direct ACL repair

Direct repair of the anterior cruciate ligament (ACL) is a surgical technique aimed at repairing the damaged ligament rather than replacing it with a graft, as in reconstruction.
This approach is less common than ACL reconstruction, but it may be appropriate in certain specific cases.

Anterolateral ligament reconstruction or combined reconstruction

Anterolateral ligament (ALL) reconstruction is a surgical procedure aimed at restoring lateral and rotational stability of the knee after rupture of this ligament.
It is often performed in addition to anterior cruciate ligament (ACL) reconstruction when both ligaments are damaged.

Indications for ALL reconstruction
Rotational instability:

ALL reconstruction is indicated in cases of persistent rotational instability of the knee, often felt as a "giving way" or a "pivot shift" during specific movements.

Concomitant ACL rupture:

It is often performed in combination with ACL reconstruction when both ligaments are torn.

Failure of conservative treatment:

When non-surgical methods, such as rehabilitation and the use of knee supports, are not sufficient to stabilize the knee.

Objectives of ALL reconstruction
– Restore rotational stability: prevent the tibia from rotating excessively relative to the femur.
– Improve overall knee function: reduce pain, improve mobility, and enable a return to normal and sports activities.
– Prevent secondary injuries: reduce the risk of further damage to knee structures such as the menisci and cartilage.

Steps of ALL reconstruction
Preparation for surgery:

The patient is placed under general or spinal anesthesia.
The knee is cleaned and prepared for the procedure.

Surgical access:

One or more incisions are made to access the ALL site and to insert the arthroscope if necessary.

Graft harvesting:

A graft is harvested either from the patient’s hamstring tendons (semitendinosus and gracilis) (autograft) or from a donor (allograft).

Preparation of the insertion site:

The ligament attachment points on the femur and tibia are prepared. This often involves creating bone tunnels to allow fixation of the graft.
Graft fixation:

The graft is passed through the created bone tunnels and fixed using devices such as screws, buttons, or staples to ensure solid fixation.
Graft tension is adjusted to mimic the natural tension of the ALL and restore knee stability.

Stability check:

Knee stability is checked with movement tests to ensure the graft is correctly positioned and fixed.

Closure of incisions:

The incisions are closed using sutures or adhesive dressings.

Postoperative rehabilitation

Initial phase:

The knee is protected with a brace, and the use of crutches is recommended to limit weight-bearing on the joint.
Pain and swelling management with medication, ice, and leg elevation.
Rehabilitation program:

A progressive physiotherapy program is essential to restore mobility, strengthen muscles, and improve proprioception.
Rehabilitation exercises are adapted to each phase of healing, ranging from passive mobilization to advanced functional rehabilitation.
Gradual return to activities:

Return to daily and sports activities is gradual, generally between 6 and 12 months after surgery, depending on the patient’s progress and the advice of the surgeon and physiotherapist.

Expected outcomes
Improved stability: most patients regain significant rotational and anteroposterior knee stability.
Functional recovery: patients can expect improved overall knee function, reducing pain and improving mobility.
Return to activities: most patients can resume their normal and sports activities, although recovery time varies from one individual to another.

Anterolateral ligament reconstruction is an effective procedure for treating rotational instabilities of the knee, particularly when performed in combination with ACL reconstruction. With appropriate rehabilitation and rigorous medical follow-up, patients can expect to regain good knee stability and function, enabling them to resume their daily and sports activities.

Repair of the anterolateral ligament is a surgical treatment option for recent ALL ruptures, aimed at preserving the patient’s natural ligament.
This approach may offer advantages in terms of tissue preservation and recovery, although it is not suitable for all types of injuries.
A careful assessment by an orthopedic surgeon is essential to determine the best approach for each patient, and rigorous rehabilitation is crucial to optimize postoperative outcomes.

Combined ACL–ALL reconstruction

Combined reconstruction of the anterior cruciate ligament (ACL) and the anterolateral ligament (ALL) is a complex surgical procedure aimed at restoring knee stability when both ligaments are ruptured.
This technique is often used to treat severe and recurrent rotational instabilities, especially in patients who have sustained significant knee trauma.

Indications for combined ACL–ALL reconstruction
Severe rotational instability:

Combined reconstruction is indicated in cases of persistent rotational instability of the knee, often felt as a "pivot shift" or "giving way" during specific movements.
Concomitant ACL and ALL ruptures
When both ligaments are damaged, combined reconstruction may be necessary to restore overall knee stability.

Failure of previous treatments
If previous surgical procedures, such as isolated ACL reconstruction, have not succeeded in stabilizing the knee.

Objectives of combined ACL–ALL reconstruction
Restore anteroposterior stability: prevent the tibia from sliding forward relative to the femur.
Restore rotational stability: prevent the tibia from rotating excessively relative to the femur.
Improve overall knee function: reduce pain, improve mobility, and enable a return to normal and sports activities.
Prevent secondary injuries: reduce the risk of further damage to knee structures such as the menisci and cartilage.
Steps of combined ACL–ALL reconstruction

Preparation for surgery
The patient is placed under general or regional anesthesia.
The knee is cleaned and prepared for the procedure.

Surgical access
One or more incisions are made to access the ACL and ALL sites.

Arthroscopy is often used to visualize the inside of the joint and guide the procedure.

Graft harvesting:

Grafts are harvested, often from the patient’s hamstring tendons (semitendinosus and gracilis) (autograft) or from a donor (allograft).
In some cases, a synthetic graft may be used.

ACL reconstruction:

The ACL insertion site on the femur and tibia is prepared by drilling bone tunnels.
The ACL graft is passed through these tunnels and fixed using devices such as screws, buttons, or staples.

ALL reconstruction

The ALL insertion site is prepared similarly, by drilling tunnels or using bone anchors.
The ALL graft is passed through these tunnels and fixed with appropriate fixation devices.

Stability check

The stability of the reconstructed ligaments is checked with movement tests to ensure they are correctly positioned and fixed.

Closure of incisions

The incisions are closed using sutures or adhesive dressings.

Postoperative rehabilitation

Initial phase

The knee is protected with a brace, and the use of crutches is recommended to limit weight-bearing on the joint.
Pain and swelling management with medication, ice, and leg elevation.
Rehabilitation program:

Physiotherapy begins quickly to restore mobility, strengthen muscles, and improve proprioception.
Rehabilitation exercises are progressive and adapted to the different phases of healing.
Gradual return to activities:

Return to daily and sports activities is gradual, generally between 6 and 12 months after surgery, depending on the patient’s progress and the advice of the physiotherapist and surgeon.

Expected outcomes
Improved stability: most patients regain significant rotational and anteroposterior knee stability.
Functional recovery: patients can expect improved overall knee function, reducing pain and improving mobility.
Return to activities: most patients can resume their normal and sports activities, although recovery time varies from one individual to another.

Combined reconstruction of the anterior cruciate ligament and the anterolateral ligament is an effective procedure for treating complex knee instabilities.
It aims to restore rotational and anteroposterior stability, improve overall knee function, and enable a return to normal and sports activities. Appropriate rehabilitation and rigorous medical follow-up are essential to optimize outcomes and ensure a full recovery.
