Results showed medial patellofemoral ligament reconstruction with and without tibial tuberosity osteotomy yielded similar outcomes for patients with patellar instability and a tibial tuberosity-trochlear groove distance of 15 mm to 25 mm.

For patients with isolated patellofemoral osteoarthritis, second-generation onlay patellofemoral arthroplasty showed safe and acceptable results at short-term and midterm follow-up, according to published results.
