Abstract

BackgroundThe purpose of our study was to prospectively report the clinical results of 280 consecutive hips 240 patients who received a ReCap Hip Resurfacing System implant Biomet Inc., Warsaw, USA in a single district general hospital. Literature reports a large variation in clinical results between different resurfacing designs and published results using this particular design are scarce.

MethodsMean follow up was 3.3 years 1.0 to 6.3 and four patients were lost to follow-up. All patients were diagnosed with end-stage hip osteoarthritis, their mean age was 54 years and 76.4% of all patients were male.

ResultsThere were 16 revisions and four patients reported a Harris Hip Score <70 points at their latest follow up. There were no pending revisions. Kaplan-Meier implant survival probability, with revision for any reason as endpoint, was 93.5% at six years follow-up 95%-CI: 88.8-95.3. There were no revisions for Adverse Reactions to Metal Debris ARMD and no indications of ARMD in symptomatic non-revised patients, although diagnostics were limited to ultrasound scans.

ConclusionsThis independent series confirms that hip resurfacing is a demanding procedure, and that implant survival of the ReCap hip resurfacing system is on a critical level in our series. In non-revised patients, reported outcomes are generally excellent.
