This protocol concerns an academic, multicentric, and prospective clinical trial. In this study the investigators will evaluate the recently approved WAVE-plate (7S Medical) for open reduction and internal fixation and buttressing of the posterior proximal tibial column via a posteromedial reversed L-shaped approach. The reversed L-shaped approach has been shown as a safe technique with adequate visualisation of the posterior tibial surface. The investigators will thoroughly evaluate all important clinical, radiological and functional variables. The functional outcome will be reported in patient reported outcome measures by means of the validated Knee injury and Osteoarthritis Outcome Score (KOOS).
