Radiographic Measurements Correlate to Isolated Posterolateral Corner (PLC) Injury in a Novel Cadaveric Model

Introduction: Injury to the posterolateral corner (PLC) of knee often requires surgical reconstruction. There remains no consensus on treatment for PLC injury, and, therefore, it is imperative have a reproducible injury model improve general knowledge injuries. A novel cadaveric isolated proposed and evaluated using radiographic parameters as well gross dissection. Material methods: All protocols were reviewed by Human Investigation Research Committee home institution approved. Translational force in defined posterior lateral direction was applied native knees induce injury. Varus recurvatum stress fluoroscopic imaging obtained each specimen before after model. Lateral joint distance angle measured image via picture archiving communication software (PACS) software. After model, injured structures assessed saline loading Any specimens found be fractured excluded from analysis radiography. Results: total 12 underwent testing 6/12 successfully induced without fracture. The capsule torn every specimen. popliteofibular ligament (PFL) 83% fibular collateral (FCL) 66.7% specimens. median gapping under varus radiography 5.39 mm 14.25°. Radiographic had direct relationship with number injured. Conclusions: This first successful cadaver emphasizing importance this structure PLC.
