Aims. The Birmingham Hip Resurfacing (BHR) was introduced in 1997 to address the needs of young active patients using a historically proven large-diameter metal-on-metal (MoM) bearing. A single designer surgeon’s consecutive series of 130 patients (144 hips) was previously reported at five and ten years, reporting three and ten failures, respectively. The aim of this study was to extend the follow-up of this original cohort at 25 years. Methods. The study extends the reporting on the first consecutive 144

A series of 100 consecutive osteoarthritic patients was randomised to undergo total knee replacement using a Miller-Galante II prosthesis, with or without a cemented polyethylene patellar component. Knee function was evaluated using the American Knee Society score, Western Ontario and McMaster University Osteoarthritis index, specific patellofemoral-related questions and radiographic evaluation until the fourth post-operative year, then via questionnaire until ten years post-operatively. A ten-point difference in the American Knee Society score between the two groups was considered a significant change in knee performance, with α and β levels of 0.05. The mean age of the patients in the

Recent events have highlighted the importance
of implant design for survival and wear-related complications following
metal-on-metal hip resurfacing arthroplasty. The mid-term survival
of the most widely used implant, the Birmingham Hip Resurfacing
(BHR), has been described by its designers. The aim of this study
was to report the ten-year survival and patient-reported functional
outcome of the BHR from an independent centre. In this cohort of 554 patients (646 BHRs) with a mean age of
51.9 years (16.5 to 81.5) followed for a mean of eight years (1
to 12), the survival and patient-reported functional outcome depended
on gender and the size of the implant. In female hips (n = 267)
the ten-year survival was 74% (95% confidence interval (CI) 83 to
91), the ten-year revision rate for pseudotumour was 7%, the mean
Oxford hip score (OHS) was 43 (. sd. 8) and the mean UCLA
activity score was 6.4 (. sd. 2). In male hips (n = 379) the
ten-year survival was 95% (95% CI 92.0 to 97.4), the ten-year revision rate
for pseudotumour was 1.7%, the mean OHS was 45 (. sd. 6) and
the mean UCLA score was 7.6 (. sd. 2). In the most demanding
subgroup, comprising male patients aged <
50 years treated for
primary osteoarthritis, the survival was 99% (95% CI 97 to 100). This study supports the ongoing use of
Resurfacing arthroplasty of the hip is being performed more frequently in the United Kingdom. The majority of these patients are younger than 55 years of age, and in this group the key benefits include conservation of femoral bone stock and the potential reduction in the rate of dislocation afforded by the larger
Metal-on-metal hip resurfacing enjoyed a period of increased global clinical application beginning in the early to mid-2000's. This tapered off quickly, to the point that it is now a niche surgery. One naturally asks the question, why?. The answers are quite simple: 1) There are no clinical benefits when compared with total hip replacements (THA). While many authors have tried valiantly to demonstrate a benefit clinically to performing a
