Video Summary

Adam Yenke discussed refining medial patellofemoral ligament (MPFL) reconstruction to reduce complications like patella fractures. Current literature suggests avoiding patellar bone sockets may lower fracture risk; thus, soft-tissue reconstructions like the medial quadriceps tendon-femoral ligament (MQTFL) are explored. Biomechanical testing on cadaver knees showed the distal half of the medial patellofemoral complex is the primary restraint against lateral patellar translation, while the proximal half is a secondary restraint. The study highlights the importance of understanding anatomical and functional roles in surgical techniques to improve outcomes and reduce complications, suggesting combined soft-tissue and osseous approaches for high-risk cases.
