Mobile-bearing unicompartmental knee arthroplasty

Abstract

Medial unicompartmental knee arthroplasty (UKA) has many advantages over total arthroplasty (TKA) including better function and less morbidity. However, the longterm failure rates of many designs of fixed-bearing UKA are high because of polyethylene wear, lack of sophisticated instrumentation, and imprecise patient selection. © 2005 Springer Medizin Verlag Heidelberg.
