Abstract
AbstractThe purpose of this study was to determine which factors contribute to patient satisfaction and expectations after total knee arthroplasty (TKA). A total of 109 patients (130 knees) with knee osteoarthritis who underwent primary TKA with navigation were studied. Intraoperative mediolateral laxity was measured. The factors including mediolateral laxity that affected patient satisfaction and expectations were evaluated using the 2011 Knee Society Score. Patient satisfaction after TKA correlated positively with symptoms and functional activities, and negatively with old age in univariate analysis. Multivariate analysis showed that symptoms and functional activities remained statistically significant; however, old age showed no difference. Patient expectations after TKA correlated positively with symptoms and functional activities, and negatively with mediolateral laxity at 60 degrees in univariate analysis. Multivariate analysis showed that symptoms, functional activities, and mediolateral laxity at 60 degrees remained statistically significant. In conclusion, midflexion instability was associated with worse expectations.
