Patellar reconstruction using distal femoral autograft in a patellectomized patient undergoing total knee arthroplasty.

Patellectomized patients have less satisfactory clinical outcomes after total knee arthroplasty because of a decreased extensor mechanism efficiency and potential instability attributable to loss of anterior restraint. We report a patient, with a prior history of patellectomy, who underwent simultaneous patellar reconstruction using distal femoral autograft during the total knee arthroplasty. The patient has been followed up for 24 months with excellent postoperative knee scores with radiographically established graft viability.
