Abstract

Patient expectation is the strongest predictor of satisfaction following total knee replacement. Dissatisfaction with surgery is reported in approximately 1 in 5 patients undergoing knee replacement. Unrealistic patient expectations and uninformed perceptions of potential benefits, risks and limitations of surgery lead to dissatisfaction in many cases. This study will examine the “risk-benefit” preferences in patients and surgeons considering total knee replacement as a treatment option for end-stage osteoarthritis.
