2021 Annual Meeting Knee Access Pass-Surgical Technique Spotlight: Slope Osteotomy (demo on cadaver)

Surgical Technique Spotlight: Slope Osteotomy (demo on cadaver)

Video Transcription

Video Summary

Dr. Volker Mussel from the University of Pittsburgh demonstrated an anterior deflection osteotomy, a revision knee surgery indicated mainly for cases with a tibial slope over 12 degrees and performed through the tibial tubercle for better access. He detailed the surgical steps, including exposure of the patella tendon and medial collateral ligament, precise pin placement under fluoroscopy to guide wedge resection, and careful saw cuts leaving a posterior hinge intact to avoid fractures. The goal is correcting the tibial slope by removing a wedge, typically around 10mm, preserving patella height. Fixation was shown using low-profile plates and screws with angled placement. Dr. Mussel emphasized surgical principles such as soft tissue protection, careful measurement, and screw positioning. He also demonstrated an alternative technique above the tubercle. Key tips included considering hardware removal rates and the importance of avoiding hinge fractures. The session included interactive Q&A and highlighted that this complex procedure can often be safely combined with revision ACL surgery.
