A Rare Variant of Acute Open Fracture Dislocation of Knee Joint
Acute knee dislocation usually results from high-energy trauma like motor vehicle accidents, fall from significant height and sports related injuries. Early intervention to reduce joint and recognize any limb threatening vascular injury and repair is mandatory. Knee dislocations are usually closed and very rarely associated with proximal tibia or patella fractures. We presented a very unique case of open posterior dislocation of knee joint with medial Hoffa fracture and avulsion of ligamentum patellae without any neurovascular injury. We reduced the knee joint, fixed the fracture and stabilized the patellar tendon. The fracture achieved union and patient had full range of knee motion and full weight bearing without any support or pain. To our knowledge this is the first case in the literature which does not fit into any classification system and not yet reported.
