Bailey, K. Ferguson, E. Crawfurd, P. James, P. May, S. Brown, M. Blyth, W. Leach] Purpose: It is hypothesized that mobile polyethylene bearings in total knee arthroplasty (TKA) may confer benefits with regard to range of motion and have improved clinical outcome scores in comparison with an arthroplasty with a fixed-bearing design. Our study compares clinical outcomes between patients who undergo TKA with either a rotating platform or fixed bearing using a posterior cruciate-retaining design. Methods: Three hundred and thirty-one patients were randomized to receive either a rotating-platform (161 patients) or a fixed-bearing (170 patients) implant. All patients were assessed pre-operatively and at 1 and 2years post-operatively using standard tools (range of movement, Oxford Knee Score, American Knee Society Score, SF12 and Patella Score). Results: There was no difference in pre- to 2-year post-operative outcomes between the groups with regard to improvement in range of motion (10°±16 vs. 9°±15), improvement in Oxford Knee Score (−17.6±9.9 vs. −19.1±8.4), improvement in American Knee Society Score (49.5±24.7 vs. 50.7±21.0), function (23.6±19.6 vs. 25.0±22.5) and pain (34.9±16.2 vs. 35.8±14.1) subscores, improvement in SF12 Score (10.0±16.3 vs. 12.3±15.8) or improvement in Patella Score (9.7±7.4 vs. 10.6±7.1). Conclusion: No difference was demonstrated in clinical outcome between patients with a rotating-platform and fixed-bearing posterior cruciate-retaining TKA at 2-year follow-up. Level of evidence: I.
