Management of Rare Case of Posterior Cruciate Ligament Avulsion Injury with concomitant Transverse Fracture of Patella-A Case Report

Avulsion injuries of the posterior cruciate ligament are not as common as other knee injuries. In fact, they are often subtle and more difficult to evaluate than other ligament injuries of the knee. Sometimes a posterior cruciate ligament injury occurs along with injuries to other structures in the knee such as cartilage, other ligaments, and less commonly bone. Avulsion injury of PCL with concomitant fracture of patella has not been reported in literature. The following is a case report discussing the management of such an injury. A 27 year old patient came with closed fracture of patella along with avulsion fracture of Posterior Cruciate Ligament. Tension Band wiring of patella followed by ORIF with Cancellous screw fixation of PCL avulsion fragment was done. Knee was immobilized for 6 weeks followed by active and passive mobilization to regain full movement of knee. In case of rare combination of such an injury, immobilzation to allow healing of PCL avulsion fracture may be given precedence to union of fracture patella and subsequent physiotherapy may be done to regain full range of motion.
