KINEMATIC CONDYLAR TOTAL KNEE ARTHROPLASTY - 14-YEAR SURVIVORSHIP ANALYSIS OF 208 CONSECUTIVE CASES

We performed an independent survivorship analysis on 208 Kinematic Con dylar knee replacements with a minimum follow-up of ten years and a me an of 12 years. Seven patients had been lost to follow-up. At ten year s the estimated survival was 92% (95% confidence limits 95% and 87%) a nd, when stratified for diagnosis and thickness of polyethylene there was no statistical difference (p>0.05) in survivorship of knees with o steoarthritis or rheumatoid arthritis. We conclude that the original d esign of the Kinematic Condylar knee replacement has a good record and that adequate evaluation of new designs of implant should be undertak en before they are widely introduced.
