Video Summary

This video demonstrates a trochleoplasty procedure, detailing a midline incision, lateral retinacular lengthening, and medial arthrotomy with muscle splitting. The surgeon describes exposing the trochlea using bent K-wires, creating a trough close to the articular surface with an osteotome, and making sulcus cuts with a high-speed burr. Key steps include careful flexibility of the bone flap, anchoring the new groove with sutures in cortical bone, and covering with synovium for healing. The goal is to reshape the trochlear groove to improve patellar engagement, especially important in trochlear dysplasia cases, while preserving the lateral wall.
