ABSTRACT Despite substantial advances in primary TKA, numerous studies using historic TKA implants suggest only 82% to 89% of primary TKA patients are satisfied. We reexamined this issue to determine if contemporary TKA implants might be associated with improved patient satisfaction. We performed a cross-sectional study of patient satisfaction after 1703 primary TKAs performed in the province of Ontario. Our data confirmed that approximately one in five (19%) primary TKA patients were not satisfied with the outcome. Satisfaction with pain relief varied from 72-86% and with function from 70-84% for specific activities of daily living. The strongest predictors of patient dissatisfaction after primary TKA were expectations not met (10.7x greater risk), a low 1-year WOMAC (2.5x greater risk), preoperative pain at rest (2.4x greater risk) and a postoperative complication requiring hospital readmission (1.9x greater risk). LEVEL OF EVIDENCE: Level II, prognostic study. See Guidelines for Authors for a complete description of levels of evidence.

    ABSTRACT: To evaluate the relationship between patient expectations of total joint arthroplasty (TJA) and health related quality of life plus satisfaction 6 months after surgery. Methods. This prospective cohort study included patients undergoing primary total hip (THA) and knee arthroplasty (TKA). Patients were evaluated with self-report questionnaires prior to surgery and 6 months post-surgery. Medical Outcomes Study Short Form 36 (SF-36), the Western Ontario McMaster Universities Osteoarthritis Index (WOMAC), and a satisfaction scale were used to evaluate outcomes at final followup. Multivariate regression models were used to evaluate the impact of expectations on outcomes. There were 102 patients with THA and 89 with TKA. Mean age was 66 years. All patients achieved significant improvements in their WOMAC and SF-36 scores following surgery. Patient expectations regarding surgery were not associated with their age, gender, index joint of surgery, marital status, or race. Expectations were not correlated with pre-operative functional health status. Expectation of complete pain relief after surgery was an independent predictor of better physical function and improvement in level of pain at 6 months post-surgery. Expectation of low risk of complications from TJA was an independent predictor of greater satisfaction. Patient expectations were important independent predictors of improved functional outcomes and satisfaction following TJA. Greater understanding of the relationship between expectations and outcomes may improve the process of care and outcomes of TJA.

  • Article: Validation study of WOMAC: a health status instrument for measuring clinically important patient relevant outcomes to antirheumatic drug therapy in patients with osteoarthritis of the hip or knee.

    ABSTRACT: Within the context of a double blind randomized controlled parallel trial of 2 nonsteroidal antiinflammatory drugs, we validated WOMAC, a new multidimensional, self-administered health status instrument for patients with osteoarthritis of the hip or knee. The pain, stiffness and physical function subscales fulfil conventional criteria for face, content and construct validity, reliability, responsiveness and relative efficiency. WOMAC is a disease-specific purpose built high performance instrument for evaluative research in osteoarthritis clinical trials.

    Article: Measuring the accuracy of diagnostic systems.

    [show abstract] [hide abstract]
    ABSTRACT: Diagnostic systems of several kinds are used to distinguish between two classes of events, essentially "signals" and "noise". For them, analysis in terms of the "relative operating characteristic" of signal detection theory provides a precise and valid measure of diagnostic accuracy. It is the only measure available that is uninfluenced by decision biases and prior probabilities, and it places the performances of diverse systems on a common, easily interpreted scale. Representative values of this measure are reported here for systems in medical imaging, materials testing, weather forecasting, information retrieval, polygraph lie detection, and aptitude testing. Though the measure itself is sound, the values obtained from tests of diagnostic systems often require qualification because the test data on which they are based are of unsure quality. A common set of problems in testing is faced in all fields. How well these problems are handled, or can be handled in a given field, determines the degree of confidence that can be placed in a measured value of accuracy. Some fields fare much better than others.
