摘　　要：Unicompartmental knee arthroplasty(UKA) has evolved into a suitable option for diseased knees that cannot be managed with arthroscopic treatment and at the same time are not good candidates for total knee replacement. Since meticulous execution of the surgical technique is essential to optimizing UKA outcome, some procedural key-points are mandatory. Templates(phantoms) are then used to size the required prosthetic component(using these radiographs. Arthritic varus(or valgus) knees with an asymptomatic patellofemoral joint are typically ideal for UKA. Metal-backed tibial components should be favourite instead of allpolyethylene tibial components to avoid polyethylene creep that may occur in fixed bearings. Moreover, a proper thickness of the polyethylene layer is mandatory, in order to avoid early failure.Unicompartmental knee arthroplasty(UKA) has evolved into a suitable option for diseased knees that cannot be managed with arthroscopic treatment and at the same time are not good candidates for total knee replacement.
