Posterolateral Corner Injuries

This chapter presents a case study of a 32‐year‐old hockey player injured his knee after suffering a pivoting injury playing hockey one month ago. His physical exam reveals 10 mm of lateral opening on varus stress with no endpoint, a positive posterolateral drawer test, and a positive dial test at 30 ° of flexion. There has been much debate in the literature regarding the decision to repair or reconstruct the posterolateral corner (PLC) in patients with high‐grade injuries. In general, repair of the PLC involves repair of the lateral collateral ligament (LCL) and other anatomic structures of the PLC to their anatomic locations. Strong evidence to establish the optimal technique for reconstruction of PLC injuries will allow for improved outcomes for patients.
