Excessive knee pivoting that causes a complete anterior cruciate ligament (ACL) tear may result in a subchondral compression fracture on the lateral femoral condyle after impacting the lateral tibial condyle. Because this mechanism is similar to the humeral head that has an impact on the glenoid during an anterior shoulder dislocation, such an osteochondral fracture can be considered equivalent to a "Hill-Sachs lesion of the knee." Restoring the native anatomy of the lateral femoral condyle articular surface is crucial, because its depression alters knee biomechanics, leading to bony knee instability, potentially greatly elevating the risk of ACL reconstruction failure and meniscal tears.
