Irreducible traumatic knee dislocation is rare. The knee dislocation is classified depending on the incarcerated structures. Complete reduction is achieved by extracting the incarcerated structure. Several reports introduce the reduction of irreducible traumatic knee dislocation by open surgery or arthroscopy. This case describes irreducible posterolateral knee dislocation with interposition of the vastus medialis. Closed reduction failed in the emergency room, and complete reduction was attained by arthroscopically sectioning the muscle and fascia of the vastus medialis in the intercondylar notch.
Key Words: Knee; Dislocation; Vastus medialis
