AANA Knee Arthroscopy - September 2024-Complications of MPFL Surgery

Video Transcription

Video Summary

This talk addresses complications in medial patellofemoral ligament (MPFL) reconstruction, emphasizing avoidance strategies. Key issues include re-dislocation, fractures, patellar bone loss, arthritis from maltracking, and medial subluxation, often caused by improper patient selection, tunnel placement, or graft tension. Avoid MPFL alone if TT-TG distance exceeds 15-20 mm or in patella alta; consider osteotomies and ensure graft is isometric. Use small anchors and avoid excessive lateral release. For femoral tunnel placement, palpate first, check isometry, then confirm with fluoroscopy. Careful technique and patient selection prevent failure, bone loss, and joint arthritis, improving long-term outcomes.
