Abstract
Introduction
The use of a mobile-bearing knee system is increasing in modern total knee arthroplasty (TKA). Mobile-bearing TKA improves kinematics and is reliable and capable of providing substantial benefit for patients. The aim of this study was to report independent long term results of uncemented low contact stress (LCS) mobile bearing total knee replacement
Methodology
We examined the outcome of 138 consecutive patients who underwent uncemented LCS total knee replacement between 1996 and 2000. Oxford knee score was noted.
Results
138 patients underwent LCS total knee replacement during this period. The mean age was 71(37-90) years. 34 patients died and 104 patients were included in the study. The mean follow up was 10 (8-12) years. There was a significant improvement in the postoperative knee scores (P<0.001). 2 knees were revised, one due to infection and due to the subsidence of the tibial tray.
Conclusion
The study has demonstrated excellent long term survivorship of the uncemented LCS total knee replacement irrespective of the deformity and diagnosis.
