Mid- to long-term results of revision total knee replacement using press-fit intramedullary stems with cemented femoral and tibial components

摘要: This was a retrospective analysis of the medium- to long-term results 46 TC3 Sigma revision total knee replacements using long uncemented stems in press-fit mode. Clinical and radiological took place pre-operatively, at two years post-operatively, at mean follow-up 8.5 years (4 to 12). The pre-operative International Knee Society (IKS) clinical score 42 points (0 74), improving 83.7 (52 to 100) by final follow-up. IKS for function improved from 34.3 80) 64.2 (15 100) follow-up. At 30 knees (65.2%) had an excellent result, seven (15.2%) good one (2.2%) medium eight (17.4%) poor result. There were failures, with anteroposterior instability and aseptic loosening. system, when used long intramedullary cemented femoral tibial components, in both septic revisions, satisfactory clinical outcome, has medium- long-term survival rate.
