What Is A Revision ACL Reconstruction?
The anterior cruciate ligament (ACL) is the most commonly injured ligament in the knee, often seen in the athletic population. The ACL plays a vital role in providing stability during twisting and rotational movements, and it also prevents the shinbone from moving too far forward in relation to the thighbone. Due to its poor blood supply and the overall anatomy of the knee joint, the ACL does not typically heal on its own if an injury occurs. As a result, many athletes and active individuals choose to undergo an ACL reconstruction procedure to restore full function and stability to the injured joint. Although ACL surgery is highly effective in repairing a torn ligament, there is a risk of re-injury.
What Causes An ACL Reconstruction To Fail?
The primary reason for a failed ACL reconstruction is a poorly placed graft during the initial surgery. A re-tear of the ligament can also occur if the patient does not follow rehabilitation guidelines or returns to athletic activities too soon. Additionally, new trauma to the ligament can cause a re-tear. Malalignment of the lower extremity, such as bow-leggedness or knocked knees, can also cause a failed reconstruction as the knees may experience uneven stress loads due to poor leg alignment.
When To Have Revision ACL Surgery?
In the event that a knee revision surgery is needed, a thorough examination of the injured joint will be performed by the surgeon to identify the underlying cause of failure. This detailed assessment is crucial to prevent a recurrence of failure. In addition, new diagnostic testing images will be obtained to assess the condition of the bone and soft tissue structures in the knee joint. If a re-tear is identified, the surgeon will perform a revision ACL reconstruction to restore full function, mobility, and stability to the joint. Similar to primary ACL surgery, the surgeon will use either an allograft or autograft to reconstruct the damaged ligament.
