Patients' reasons for undergoing total hip arthroplasty can change over time.

The purpose of this study was to determine if a patient's reasons for undergoing a primary total hip arthroplasty (THA) changed at 1 year follow-up and, if the reasons did change, how does this change influence patient satisfaction with the procedure. Patients undergoing THA (101 patients) were evaluated with the McMaster Toronto Arthritis Patient Preference Disability (MACTAR) questionnaire and questions related to their expectations regarding the procedure. With the exception of pain and walking, most patients did not select the same preoperative and postoperative reasons for undergoing the procedure. In fact, 60% chose 2 new postoperative items. Patients whose expectations were not met were less likely to choose the same reasons for undergoing THA. Surgeons need to clarify patients' reasons for wanting a THA and attempt to identify new factors at follow-up that may influence patient satisfaction with the procedure.
