Patient-reported outcome of hip resurfacing arthroplasty and standard total hip replacement after short-term follow-up

Introduction: The purpose of this study was to investigate patient-reported outcome in terms of satisfaction in two study groups that had undergone hip resurfacing arthroplasty (HRA) or total hip replacement (THR). The procedure consists of placing a hollow, mushroom-shaped metal cap over the femoral head while a matching metal cup is placed in the acetabulum (pelvis socket).

Material and methods: The two study groups included a total of 84 patients with an average age of 57 years who had idiopathic hip osteoarthritis or secondary arthritis based on mild dysplasia with arthritis. A descriptive cross-sectional design was used. A patient-reported questionnaire was used to evaluate patient outcome three years after hip surgery.

Results: The study showed that both groups (HRA and THR) reported high levels of overall satisfaction, with 97% and 93% being very satisfied or satisfied. Men were more satisfied with their ability to walk longer distances than women (p < 0.05) and the THR group claimed to be treating their artificial hip with more caution than the HRA group (p < 0.05).

Conclusion: The choice of prosthesis (HRA or THR) does not appear to affect the overall satisfaction or patient- perceived functional outcome three years after surgery in patients who on average were 57 years old and who had idiopathic hip osteoarthritis or secondary arthritis based on mild dysplasia.
