[Total knee joint replacement with a rotating hinge endoprosthesis in light of late results]

Results of 15 total knee replacements with rotating hinge endoprosthesis in 13 rheumatoid patients with an average follow-up of 7 years and 11 months are presented. C.R.S. point scale served to assess results. As to pain, range of motion, stability and alignment good results have been achieved in all cases. Ability to ambulate was diminished due to general condition of rheumatoid patients (8 of them had total hip and/or contralateral total knee replacement). Results of hinge tkr with the same follow-up yielded 33% failures. In conclusion rotating hinge tkr is markedly better than hinge type knee arthroplasty.
