Total Knee Arthroplasty for Neglected Habitual Dislocation of Patella with Knee Osteoarthritis: A Case Report.

CASE: 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.

CONCLUSION

TKA 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.
