Intra and Extra Articular Proximal Tibial Osteotomies combined with Multi-Ligament Reconstruction using Patient Specific Instrumentation – a Rare Case Report

We report a case of a 19 year old presenting with a traumatic fracture dislocation of the knee joint. Managed initially in an external fixator, this patient was left with a malunited depressed articular fragment of the medial compartment with associated multi-ligament knee injury. A novel technique using four patient specific instrumentation guides to correct both intra and extra-articular deformities and multi-ligament injuries is described.
