Multiple ligament injury is associated with high instability; hence, it is necessary to restore stability through application of a reliable treatment strategy. We report our experiences in handling a case of ruptured anterior cruciate ligament (ACL) complicated by chronic bony avulsion of the posterior cruciate ligament (PCL). Favourable results were obtained as a result of ACR reconstruction following a new method for tensioning of the chronic tibial bony avulsion of PCL as a postero-medial bundle and augmentation by PCL anterolateral bundle reconstruction. Favourable posterior stability could be restored through application of this new technique incorporating post-reconstruction PCL reinforcement.
