ABSTRACT

BACKGROUND:

Failure of anterior cruciate ligament reconstruction can be caused by multiple factors, which requires a revision surgery. However, there are few studies about the revision of anterior cruciate ligament.

OBJECTIVE:

To investigate the primary cause, indication, methods and effectiveness of revision after the failure of anterior cruciate ligament reconstruction.

METHODS:

Thirty patients with instability undergoing anterior cruciate ligament reconstructions were subjected to revision under arthroscopy. After revision, a systemic analysis was performed based on KT-2000 examination, the International Knee Documentation Committee (IKDC) scale, Lysholm and Tegner scores. RESULTS AND

CONCLUSION:

Of the 30 cases, 9 cases were reconstructed with bone-patelar tendon-bone autograft, 14 cases with hamstring tendon autograft, 7 cases with hamstring tendon alograft. Twelve cases had a femoral tunnel in the front of the predicted one, 1 case had knee stiffness, 8 cases had a tibial tunnel in the front of the predicted one, and 8 cases had both the femoral and tibial tunnels in the front of the predicted ones. One case had a malposited interference screw which reconstructed with bone-patelar tendon-bone autograft; one case complicated by posteromedial corner injury was not reconstructed. The reconstructed anterior cruciate ligament was absolutely ruptured and absorbed in 12 cases, and 18 cases had obviously loosen but stil partly linked reconstructed ligament. None had severe incompletion of spongy bone. Al cases received primary revision. Ten cases reconstructed with ipsilateral hamstring tendon, 14 cases reconstructed with contralateral hamstring tendon, and 6 cases with LARS ligament. The mean side-to-side difference of KT-2000 examination at 90° and 30°, the mean IKDC, Tegner and Lysholm scores were significantly improved after revision. There were many reasons leading to failure of anterior cruciate ligament reconstruction, such as malposition of the bone tunnel, invalid fixation, adhesion, compound ligament injuries, and ankylosis. The functional results and objective stability could be obtained through revision folowing anterior cruciate ligament reconstruction.
