ICL 306: Avoiding Complications in Patellofemoral Instability Surgery: MPFL Reconstruction-Medial Quadriceps Tendon-Femoral Ligament Reconstruction (MQTFL) Reconstruction

Medial Quadriceps Tendon-Femoral Ligament Reconstruction (MQTFL) Reconstruction

Video Transcription

Video Summary

The speaker discusses surgical techniques for patellar instability focusing on medial quadriceps tendon femoral ligament (MQTFL) reconstruction and tibial tubercle transfer. Emphasizing proper patellar alignment, the goal is to centralize tracking without routine trochleoplasty. Key technical points include performing a flat, tapered osteotomy during tubercle transfer to avoid fractures, ensuring visualization of the saw blade to prevent nerve injury, and tapering the osteotomy anteriorly for secure fixation and quick healing. The medial graft should be placed anatomically at the adductor tubercle, avoiding malposition that leads to failure. Early controlled motion post-surgery is encouraged, with screw removal around six months to reduce stress risers and a conservative one-year delay before contact sports. Proper technique significantly reduces complications like fractures, skin damage, or instability. The speaker stresses that mastering anatomy and surgical precision yields high success and patient satisfaction in managing patellar instability.
