Brief CommunicationThe Relationship Between Expectations and Satisfaction in Patients Undergoing Primary Total Knee Arthroplasty
Section snippets
Methods
English-language studies were identified by searching CINAHL, Cochrane library, EMBASE, PubMed, and PsycINFO electronic databases using the following inclusion criteria: primary TKA, diagnosis of knee osteoarthritis (OA), presurgery outcome measures, a measure of patient expectations, a measure of patient satisfaction, and multivariate analysis of the relationship between expectations and satisfaction reported separately for TKA recipients. Additional articles were identified by searching for
Results
Five studies met the inclusion criteria. One study analyzed the relationship between preoperative patient expectations and satisfaction [3]; one study evaluated the relationship between differences in preoperative and postoperative expectations and satisfaction [4]; the third study tested for the separate relationships of preoperative and postoperative expectations with satisfaction [5]; and the other 2 analyzed the relationship between postoperative expectations and satisfaction 6, 7. In each
Discussion
Our hypothesis was that no significant relationship would exist between preoperative expectations and patient satisfaction after primary TKA, when other possible confounders are controlled for in the analysis. Neither of the 2 studies that analyzed the relationship between preoperative patient expectations and postoperative patient satisfaction found a significant association. Mannion et al [4] was the only study that measured a change in expectations but found no relationship between their
