Video Transcription

Video Summary

In this video, Joe Featherall discusses the challenges of medial patellofemoral ligament (MPFL) reconstruction in pediatric patients. He explains that the main technical challenge is anatomic femoral tunnel placement without causing injury. He mentions common failures, such as proximal anchor migration, sagittal and coronal deformities, and graft failure. Featherall highlights the conflicting data on the insertion location of the MPFL and the limitations of previous studies. To determine the position of Schottel's point as a landmark for femoral tunnel reaming, Featherall and his team performed a study using two institutions' CT data and a 3D image computing platform. Their results show that Schottel's point is consistently distal to the medial distal femoral fices, making it a reliable radiographic landmark for pediatric MPFL reconstruction.
