Scope Essentials 2024-Managing the Posterolateral Corner

Video Transcription

Video Summary

Dr. Michael Alea, Associate Professor of Orthopedic Surgery at NYU Langone Health, discusses the complexities of posterolateral corner (PLC) knee surgery. He emphasizes the importance of careful planning, adequate exposure, and respecting anatomy and timing, especially in acute injuries like distal avulsions, which benefit from early repair with augmentation. Peroneal nerve assessment via MRI is crucial to prevent iatrogenic injury. Avoiding contraindications such as significant varus deformity is vital; osteotomies may be needed prior to reconstruction. Different reconstruction techniques (LaPrade, Larson, Arciero) suit varied instability patterns. Dr. Alea advocates for a methodical approach: fix the PCL first, then the PLC, and ACL last, ensuring stable knee alignment during tensioning. Postoperative laxity is normal, and surgeons must continually learn from each case. He underscores the art of treating multiligament injuries, encouraging ongoing research, self-assessment, and sharing knowledge to improve patient outcomes in this challenging field.
