A statistical review of 100 consecutive "U.C.I." low friction knee arthroplasties with analysis of results.

In 100 U.C.I. low friction knee arthroplasties, the primary goal of relief from pain was accomplished in most patients. However, the precise evaluation of the result of a knee arthroplasty can be difficult. Many of the patients who rated good or better within an average follow up time of one year had patellofemoral complaints to some extent. Cold flow deformation and prosthetic loosening is a definite concern about the tibial component. A longer follow-up study is needed to better evaluate the significance of the 1-2 mm radiolucent line at the bone cement interface of the tibial component. Although most patients in this series were greatly relieved of their pain, even better results are possible if the arthroplasty would include the patellofemoral joint and tibial component more substantially bonded to cancellous bone.
