Case Report
We performed total knee arthroplasty (TKA) on a 62-year-old male patient who presented with symptomatic knee osteoarthritis resulting from habitual dislocation of the patella. The patient had a painless unassisted gait with stable patella and 5 to 95° knee range of motion, 23 months after surgery./r/nTKA can be an effective treatment option for geriatric patients with habitual patellar instability and concomitant knee osteoarthritis, but may require surgical modifications based on individual pathoanatomy.
