Longer operation times, poorer patient outcomes and increased early post-operative complications are reasons cited for not undertaking Total Knee Arthroplasty (TKA) on morbidly obese patients. This study tests the hypothesis that there is no difference in intra-operative parameters between morbidly obese and non-obese patients, and no difference in patient outcome.Intra-operative parameters, post-operative...
The surface characteristics of the femoral component affect polyethylene wear in modular total knee replacements. In the present retrieval study, the surface characteristics of cobalt–chromium (CoCr) alloy and oxidized zirconium (OxZr) femoral components were assessed and compared.Twenty-six retrieved CoCr alloy femoral components were matched with twenty-six retrieved OxZr femoral components for...
Despite the excellent total knee arthroplasty (TKA) results reported using traditional outcome measures, dissatisfaction rates of up to 30% are reported following surgery. Although several preoperative factors have been identified as possible predictors of satisfaction, there is conflicting evidence. Identification of dissatisfaction in the early postoperative assessment may therefore be an alternative...
