To identify the responsiveness, minimal clinically important difference (MCID), minimal clinical important change (MIC), and patient-acceptable symptom state (PASS) thresholds in the 36-item Short Form Health Survey questionnaire (SF-36) (v2) for each of the eight dimensions and the total score following total knee arthroplasty (TKA). There were 3,321 patients undergoing primary TKA with preoperative and one-year postoperative SF-36 scores. At one-year patients were asked how satisfied they were and “How much did the knee arthroplasty surgery improve the quality of your life?”, which was graded as: great, moderate, little (n = 277), none (n = 98), or worse.Aims
Methods
We wished to quantify the influence of constraint and various principal indications upon functional outcome following aseptic first time revision knee arthroplasty. In this single centre, prospective study we have looked into the outcome of 175 total revision knee replacement performed between 2003 and 2008 at a minimum follow-up of 1 year. Data was refined to allow for examination exclusively of those cases where the level of constraint was increased from cruciate retaining or cruciate sacrificing knee replacement to either non linked constrained implant (condylar constrained) or linked constrained (rotating hinge) prosthesis.Introduction
