“…1,10,11,18–20 Gross et al 21 attributed <1% of their revisions to ARMD which is similar to our series. Baad-Hansen et al 20 found no rotation or migration of the components in their series based on radioisometric analysis at 2 years. Van der Weegan et al 1 had good to excellent results in 94% of cases in their follow-up of 3 years.…”

Introduction: We present the 10-year results of the ReCap Magnum HRA system in a consecutive single surgeon's series from a non-designer centre. Patients and methods: Hip resurfacing arthroplasty (HRA) was performed in active males under 65 years and in premenopausal females with adequate bone density proven by a DEXA scan. Clinical follow-up; annual Oxford hip scoring, UCLA scoring and whole blood metal ion level measurement. Kaplan-Meier method was used to determine survivorship with revision as the end point. Radiographs were analysed for; acetabular inclination, notching, neck thinning and change in implant position. 72 HRAs were performed in 66 patients with a mean age of 45.7 years. The mean follow-up was 10.63 ± 0.54 years (range 10-11.75 years). Results: The survivorship of the cohort at minimum 10 years was 97.22% (95% confidence interval 94.14-99.01). There was a significant improvement in the Oxford Hip Score from 15.77 ± 4.33 to 45.67 ± 4.43 (p < 0.001) and the UCLA score from 3.14 ± 0.74 to 7.07 ± 1.16 (p < 0.001). Mean whole blood cobalt and chromium levels were 28.83 ± 8.42 nmol/l and 39.93 ± 9.64 nmol/l respectively. There were 2 revisions, due to avascular necrosis and implant failure. In our series the implant has performed well with <1% failure per year. We did not note any difference between the genders, since all the females in our series had been screened for osteopenia using a DEXA scan. All our patients returned to an active lifestyle which was maintained at final follow-up. Conclusion: Strict selection criteria and a well-designed implant result in good long-term functional and radiological results with hip resurfacing.

“…Baad-Hansen et al conducted a radiostereometric analysis (n = 23). There was no statistically significant translation or rotation of the femoral component observed after two years FU [8]. The absence of any revisions in these series might be due to the small number of patients and the short FU.…”

“…Gagala reported there were no significant complications after a maximum follow up (FU) of 20 months, using this implant design (n = 23) [7]. Baad-Hansen reported no significant translation or rotation using this implant design (n = 25), after two year FU using radiostereometry (RSA) [8]. A larger number of ReCap procedures (n = 137) with a three year FU are described in the Australian National Joint Replacement Registry.…”

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.Trial registrationClinicalTrials.gov Identifier: NCT00603395

“…To our knowledge, there are no other studies which have investigated the prevalence of pseudotumours with this particular HRA design using imaging modalities other than plain radiographs. The studies by Baad-Hansen and Gagala were limited to 23 and 25 HRA patients respectively with a maximum follow-up of 24 months (23, 24), Gross and Liu recently published a case series of 740 consecutive procedures with the ReCap HRA design with a follow-up of seven years maximum (25). The reported Kaplan-Meier survivorship with any revision as an end point was 96.4% at 7 years, with only two revisions (0.3%) for adverse wear.…”

High Incidence of Pseudotumours after Hip Resurfacing Even in Low Risk Patients; Results from an Intensified MRI Screening Protocol

et al. 2012

We intensified our screening protocol for the presence of pseudotumours in a consecutive series of patients with a hip resurfacing arthroplasty (HRA), to establish whether we should be alert to the presence of 'silent' pseudotumours. Patients categorised with high risk (11 hips) and low risk (10 hips) for pseudotumour development and a control group (23 hips) were screened with metal artefact reduction sequence (MARS) magnetic resonance imaging (MRI). The Anderson classification to grade any metal-on-metal (MoM) disease present on MARS-MRI images was used. In 15 out of 44 MRI scans pseudotumours were observed (34.1%), of which six were graded with mild (13.6%), eight with moderate (18.2%) and one with severe MoM disease (2.3%). Twelve pseudotumours were present in asymptomatic patients (27.3%). Metal ion levels were normal in 80% of the MARS-MRI screened patients. As a consequence of our intensified screening protocol, one patient was revised for pseudotumour formation and another patient was scheduled for revision. Silent pseudotumours were observed in all three groups. Before our intensified screening protocol was initiated, no pseudotumours were encountered in our cohort of 289 HRAs. We concluded that clinical outcomes and plain radiographs for screening MoM patients underestimates the presence of pseudotumours in MoM patients. The true clinical relevance of these pseudotumours is still unclear.
