No decline in high patient satisfaction after total hip arthroplasty at long-term follow-up

Patient satisfaction is gaining popularity as an important outcome parameter in today’s healthcare system and in particular in evaluating the outcome of joint arthroplasty. Total hip arthroplasty (THA) is a very successful procedure with reports on high patient satisfaction at short-term follow-up. Commonly used clinical outcome parameters remain good at long-term follow-up; however, whether this also accounts for patient satisfaction remains unclear. This study presents a prospective follow-up of patient satisfaction after THA, and a possible correlation with common outcome parameters was established.
This study entails a concise follow-up of an earlier study on patient satisfaction 2.5 years after THA. Patient satisfaction was repeatedly measured with a visual analogue scale (VAS) after a mean follow-up of 13.5 (12.6–14.2) years in a prospective cohort of 147 patients (153 THAs). In addition, VAS pain and common clinical outcome parameters (WOMAC, OHS and SF-36) were also reassessed and were compared with short-term results after a mean follow-up of 2.5 (1.3–3.0) years.
At a follow-up of 13.5 (12.6–14.2) years, the median VAS for satisfaction was 95 (26–100) compared to a median VAS satisfaction of 98 (0–100) at earlier follow-up (p = 0.781). Overall, the clinical outcome parameters also remained good at long-term follow-up without significant changes. However, a rather low correlation with VAS satisfaction was encountered. Pain during activity showed the highest correlation (− 0.686) with VAS satisfaction.
Patient satisfaction after THA remains high after prolonged follow-up. Apparently patients do not get used to the successful results of their THA. A rather low correlation with common clinical outcome parameters suggests that patient satisfaction is a separate entity. Since patient satisfaction correlated best with pain during activity, this is probably the most important aspect in patient satisfaction. Measurement of patient satisfaction has additional value and may even replace some of the more commonly used questionnaires.
