Rare Fracture Knee Dislocation Treated with Ligament Repair and Novel Arcuate Fracture Repair Technique

Abstract

Case: A 57-year-old man presented with a left knee dislocation after a motor vehicle collision. Clinical and imaging evaluation demonstrated disruption of the anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), anterolateral ligament (ALL), and posterolateral corner (PLC). The patient underwent acute, single-stage arthroscopic primary ACL and PCL repair, with arcuate fracture fixation using a novel technique. At 4 years postoperatively, he continues to do well subjectively with minimal clinical laxity. Conclusion: Acute, single-stage arthroscopic primary ligamentous repair is a viable option for high-grade multiligamentous knee dislocations and may be combined with our novel technique for arcuate fracture fixation.
