Three patients who experienced extensor mechanism rupture after total knee arthroplasty underwent reconstruction using an allograft consisting of quadriceps tendon, patella, patellar tendon, and tibial tubercle. All patients who failed initial attempts to repair the extensor mechanism disruption achieved pain relief at average 4.8-year follow-up. Patients were able to extend their knee actively against resistance. Ambulation with full weight bearing was possible in all patients; however, one patient required a cane. Few reports have been published on allograft reconstruction of the extensor mechanism. The current study supports its use for patients who have failed to achieve knee extension with reconstruction by other means.
