Total knee arthroplasty combined with medial patellofemoral ligament reconstruction for osteoarthritic knee with preoperative valgus deformity and chronic patellar dislocation.

Abstract

We report a challenging case of a 44-year-old woman who had osteoarthritis in the lateral compartment of her right knee with severe valgus deformity and chronic lateral patellar dislocation. Total knee arthroplasty was performed for the knee. However, persistent patellar dislocation remained during the surgery; and therefore, medial patellofemoral ligament (MPFL) reconstruction was additionally performed at the time of the surgery. Stable patellar tracking was obtained after the MFPL reconstruction; and during the 2-year follow-up, her knee functioned well, and no recurrent patellar dislocation was observed. This clinical case indicates the usefulness of MPFL reconstruction for obtaining stable patellar tracking during total knee arthroplasty when a tendency for lateral patellar dislocation remains.
