Video Summary

The presentation discusses when to combine tuberosity osteotomy with NPFL (medial patellofemoral ligament) reconstruction in recurrent patellar instability. Isolated NPFL reconstruction suits patients with normal alignment and medial soft tissue insufficiency. However, combining with a tuberosity osteotomy is beneficial in cases with increased TTTG distance, patella alta, trochlear dysplasia, or maltracking, as it improves stability and unloads articular surfaces. Osteotomy techniques include medializing, anteromedializing, and distalizing, chosen based on specific indications. Complications like delayed union and hardware pain are manageable. The speaker emphasizes individualized treatment planning, advocating for osteotomy when biomechanically indicated to ensure optimal patient outcomes.
