Dislocation of the knee is a serious and potentially limb threatening injury. There are 3 types of dislocation around the knee joint: patellofemoral, tibiofemoral and tibiofibular. Tibiofemoral dislocation is the variant that is deemed the most serious, with a higher risk of compromise to the popliteal artery and common peroneal nerve. Although simultaneous dislocations of two types have been described, there has been no such description of all three types occurring simultaneously. In this case we present a case of simultaneous dislocations of all 3 articulations around the knee. Diagnosis was achieved with clinical examination, plain films, CT and MRI scans. Management consisted of initial surgical debridement and reduction with stabilisation of the affected joints.
