title: Knee extensor mechanism allograft reconstruction following chronic disruption.
abstract: The management of chronic extensor mechanism disruption can be complex. One of the options is allograft reconstruction. The goal of this study was to present the surgical procedure and provide preliminary results with this technique. The allograft uses the whole extensor mechanism (anterior tibial tubercle, patellar ligament, patella, quadriceps tendon). The native patella can be completely removed if the quality of the bone is poor, otherwise a bone groovecan be created to receive the allograft. The allograft is tightly tensioned with the knee in full extension. This surgical technique was performed 5 times with a minimum follow-up of 1 year. Active extension was recovered in all cases. The mean postoperative KOOS was 55.5 the IKS function score was 68.5 and the IKS knee score was 83.
