Abstract
Introduction
The aim is to study the outcome of a consecutive single surgeon's series using the ReCap Hip resurfacing arthroplasty (HRA) system.
Methods
This is an ongoing prospective study. HRA was performed in active males under 65 years with good bone quality and in pre-menopausal females with adequate bone density proven by a DEXA scan. Radiographs were analysed for acetabular inclination, notching, neck thinning and change in implant position. Pre-op and follow-up Oxford hip and UCLA scores were recorded.
Results
72 HRA's were performed in 66 patients with a mean age of 54.7 years. The mean follow-up was 5.96±1.33 years. The mean theta angle was 38.21±4.270 and stem-shaft angle was 139.98±6.650. Femoral neck thinning was observed in two cases. There was a significant improvement in Oxford Hip score and UCLA score (p<0.001). All patients returned to their normal level of activity. We did not observe any significantly abnormal Cobalt or Chromium levels at follow-up. One hip developed avascular necrosis at three years, and was revised to a ceramic-on-ceramic bearing. The survivorship was 98.61% at 5years.
Conclusion
The ReCap hip resurfacing system demonstrated good medium-term results in a cohort of active patients, whom we will continue to monitor in the longer term.
