Video Transcription

Video Summary

Dr. Adam Yankee discusses the lateral soft tissues of the knee, focusing on the lateral patellofemoral ligament (LPFL) and related structures. He explains their anatomy, biomechanics, and clinical significance in patellar tracking and stability. The LPFL primarily functions in full knee extension to resist medial patella dislocation and should not be routinely released during patellar instability treatment. He contrasts lateral release, which can cause iatrogenic medial instability and increased patellar translation, with lateral lengthening, which better preserves knee function and decreases complications. Reconstruction of the LPFL is reserved for patients with symptomatic medial instability, often following lateral release. Two case studies illustrate surgical decisions: one with chronic lateral maltracking treated by tibial tubercle osteotomy, lateral lengthening, and cartilage transplant; another with medial instability post-lateral release treated with LPFL reconstruction using a hamstring allograft. Outcomes suggest lateral procedures must be carefully selected to maintain balance and patellar stability.
