Diagnosis and Management of Patellofemoral Cartilage Injuries (2023 Annual Meeting)-TTO

TTO - When to Do It and How to Get It Right

Video Transcription

Video Summary

Austin Stone from Kentucky discusses the tibial tubercle osteotomy (TTO) as an effective surgical procedure for patellofemoral cartilage lesions and arthritis, especially related to abnormal anatomy like patella alta and trochlear dysplasia. The TTO, often combined with anterior medialization (AMZ), reduces patellar contact forces and improves cartilage preservation. Long-term outcomes show high patient satisfaction and return to activity, even in military populations. Risks include age, anteversion, and post-op complications. TTO combined with autologous cell implantation further improves results. It's also beneficial in bipolar lesions and patellar instability when paired with MPFL reconstruction. Surgical technique emphasizes proper fixation and alignment before graft tensioning.
