Abstract
Patellofemoral problems are the most common complications after total knee arthroplasty (TKA). We report a patient who had patellar subluxation twice within 7 months after primary TKA. Postoperative radiographs and computed tomography scans revealed a valgus knee with no evidence of malposition of the prostheses. To eliminate the recurrent patellar subluxation, we finally performed an Elmslie-Trillat procedure in combination with extensive lateral release and succeeded in achieving normal patellar tracking. At 1-year postoperative follow-up, the patient was satisfied with the results. The patella tracked well in the femoral trochlear groove during knee flexion after the revision surgery. This procedure, in combination with lateral release, should be considered as a useful surgical treatment that can eliminate patellar subluxation after TKA in cases without component malposition.
