Anterolateral Ligament Reconstruction

Anterolateral ligament (ALL) reconstruction is a surgical procedure designed to enhance rotational stability of the knee, particularly in patients undergoing anterior cruciate ligament (ACL) reconstruction. This technique uses a tendon graft, often from the semitendinosus, to reinforce the ALL, which works with the ACL to stabilize the knee during twisting movements. ALL reconstruction is especially beneficial for patients with combined ligament injuries or those experiencing persistent instability after ACL surgery, reducing the risk of re-injury and improving long-term outcomes. The anterolateral ligament is a structure located on the outer side of the knee, and it plays a role in stabilizing the knee, particularly during pivoting movements.


Indications for Anterolateral Ligaments (ALL) Reconstruction:

  1. Persistent Rotational Instability: Patients who continue to experience rotational instability (pivot shift) after ACL reconstruction.
  2. High-Risk Patients: Athletes or individuals with high-demand activities who are at risk of ACL graft failure.
  3. Revision ACL Surgery: Patients undergoing revision ACL surgery who have previously failed ACL reconstruction.

Surgical Technique:

  1. Graft Selection: Similar to ACL reconstruction, autografts (from the patient's own body) or allografts (from a donor) can be used.
  2. Graft Placement: The graft is typically fixed to the femur and tibia at the anatomical attachment sites of the anterolateral ligament.
  3. Fixation: The graft is secured using screws, buttons, or other fixation devices.

Rehabilitation:

  1. Initial Phase: Focus on reducing swelling, restoring range of motion, and protecting the graft.
  2. Intermediate Phase: Gradual strengthening and proprioceptive exercises.
  3. Advanced Phase: Sport-specific drills and gradual return to activities.

Outcomes:

  1. Improved Stability: ALL reconstruction can significantly reduce rotational instability and improve overall knee stability.
  2. Reduced Re-injury Rates: May lower the risk of ACL graft failure, especially in high-risk patients.

Risks and Complications:

  1. Infection: As with any surgery, there is a risk of infection.
  2. Graft Failure: The graft may fail, leading to persistent instability.
  3. Stiffness: Some patients may experience stiffness or limited range of motion post-surgery.

Conclusion:

ALL reconstruction is a valuable adjunct to ACL reconstruction in selected patients, particularly those with significant rotational instability or those at high risk of graft failure. It is essential to have a thorough discussion with your orthopedic surgeon to determine if this procedure is appropriate for your specific condition.
