Abstract

Background

A number of reconstructive procedures are available for the management of hip
osteoarthritis. Hip resurfacing arthroplasty is now an accepted procedure, with
implant survivorship comparable to THA at up to 10 years  follow-up in certain
series. Most reports focus on implant survivorship, surgeon-derived results, or
complications. Fewer data pertain to patient-reported results, including
validated measures of quality of life (QoL) and satisfaction and baseline
measures from which to determine magnitude of improvement. Validated
patient-reported results are essential to guide patients and surgeons in the
current era of informed and shared decision making.

Questions/purposes

We determined whether patients reported improvement in disease-specific,
joint-specific, and generic QoL after hip resurfacing arthroplasty; whether
patients were satisfied with the results of the procedure; and latest activity
level and return to sport.

Methods

We retrospectively reviewed 127 patients (100 men, 27 women) who underwent
143 hip resurfacing procedures between 2002 and 2006. Mean patient age was 52
years. Patients completed the WOMAC, Oxford Hip Score, and SF-12 at baseline and
again at minimum 2-year followup (mean, 2.5 years; range, 2–6 years). At latest
follow-up, patients completed a validated satisfaction questionnaire and UCLA
activity score.

Results

All QoL scores improved (normalized to a 0–100 scale, where 100 = best health
state). WOMAC improved from 46 to 95, Oxford Hip Score from 42 to 95, SF-12
(physical) from 34 to 54, and SF-12 (mental) from 46 to 56. Patient satisfaction
score was 96. UCLA activity score was 8.

Conclusions

The majority of patients reported improvement in QoL, were very satisfied
with their outcome, and returned to a high level of activity after hip
resurfacing arthroplasty.

Level of Evidence

Level IV, therapeutic study. See the Instructions for Authors for a complete
