End-stage osteoarthritis is commonly treated with joint replacement. Despite high clinical success rates, up to 28% of patients are dissatisfied with the outcome.This best-evidence synthesis aimed to review studies with different forms of study design and methodology that examined the relationship between (fulfilment of) outcome expectations of hip and knee patients and satisfaction with outcome.A literature search was performed in PubMed, Web of Science, PsycInfo, Cochrane, and Google Scholar to identify studies conducted up to November 2017. The methodological quality of studies was assessed using the Newcastle-Ottawa Scale.In this best-evidence synthesis systematic review, the following main results could be seen. In only half of all studies were preoperative expectations associated with level of satisfaction, while in almost all studies (93%), fulfilment of expectations was related to satisfaction. The effect of met expectations did not differ between hip and knee patients or study design.Fulfilment of expectations seems to be consistently associated with patient satisfaction with outcome. Emphasis in future research must be placed on the operationalization and measurement of expectations and satisfaction to determine the (strength of the) influence of these different forms of assessment on the (existence of the) relationship.
