Die mediale Schlittenprothese mit mobilem Polyethylenmeniskus „Oxford Uni“ bei anteromedialer Gonarthrose

Abstract Medial unicompartmental knee replacement (UKR) has many advantages over total replacement (TKR) including better function and less morbidity. However, the long-term failure rates of fixed-bearing UKR are high because of polyethylene wear, lack of sophisticated instrumentation and imprecise patient selection. The fully congruent mobile bearing of the Oxford UKR exhibits minimal polyethylene wear and failure from this cause does not occur. The instrumentation allows precise implantation to restore isometric function to the ligaments. During its 20 years development, the limits of usefulness of the implant…
