 We report the case of 68-year-old woman with osteoarthritis of the knee and habitual dislocation of the patella. Dislocation of the patella occurred ever the right knee was extended more than 90°. Plain preoprerative radiographs demonstrated osteoarthritis and lateral subluxation of the patella. We treated the osteoarthritis and subluxation by total knee arthroplasty (TKA) and attempted to improve of tracking of the patella by cutting the anterior aspect of the femur as far posteriorly as possible, positioning the femoral component laterally, the tibial component in external rotation, and the patellar component medially. Dislocation of the patella was not observed at the 12-month follow-up examination.
