288:, in which the ball part of the hip joint suffers a loss of blood supply and becomes non-viable, the results of hip resurfacing are not good (less than 90% success 10 years after their operation). Osteonecrosis can occur from a variety of reasons including fracture of the femoral neck, or patients who received high dose steroids due to any medical condition or those suffering from alcohol abuse. In such patients the quality of bone in the femoral head (the ball part of the hip) is compromised and progressively crunches leading to a failure of resurfacing. For such patients with poor quality femoral head bone stock, who are unsuitable for a regular hip resurfacing, McMinn developed a conservative and more versatile metal-on-metal arthroplasty, the Birmingham Mid Head Resection (BMHR) device. The BMHR is demonstrating good medium term results in such high risk patients.
259:, England. Over the next few years its success spurred surgeons all over the United Kingdom, Europe, Australia and many parts of Asia to start performing the procedure. On 9 May 2006, the FDA approved the BHR for medical use in the United States. Following thirteen years of usage McMinn reports 96% success with his BHRs in all patients and all diagnoses. These resurfacings are particularly successful in young patients who are the worst group for THRs. His success rate of the BHR in this age group is 98% at 13 years. Several other series and national registers also show similar results of around 95% currently with the BHR. The 2009 Australian National Joint Replacement Registry reported a 95% success rate for the BHR.

nearly 20% of patients who undergo a knee replacement are dissatisfied with their outcome. In an attempt to improve the functional outcome following knee replacements McMinn developed a high performance knee which closely mimics the movement, stability and function of the natural knee to a greater extent. The world-class laboratory where the BKR was bench-tested reported that of all the artificial knees tested thus far, the BKR generated the least volume of wear. Early outcomes with the
Birmingham Knee Replacement (BKR) are very promising. Of course only time will tell if the long-term satisfaction of patients with BKRs match those with hip resurfacings.

these bearings wear at a much lower rate, provided they are manufactured according to specifications, and are implanted well. These allow the patients to return to higher levels of activity after the operation without the fear of early wear. Furthermore, because the devices have the same diameter as the patients' own, they are less prone to dislocation.
305:
Current evidence shows that although knee replacements survive almost as long as hip replacements, the outcome of available designs of knee replacements are not as good as hip replacements. While only 1–5% of patients with a THR or a hip resurfacing are unhappy with their outcomes in the early years,

McMinn first began performing hip resurfacing procedures in 1991 using the McMinn
Resurfacing, manufactured by Corin. The rationale behind the procedure was that it would be a bone-conserving alternative to THR for patients with higher activity demands i.e. young patients with severe hip arthritis

The Corin technique of resurfacing employs thin (3–4 mm) metal surfaces to line the patients' own hip. In contrast to a THR, the femoral head and neck are retained in this procedure. These large diameter resurfacings match the patient's own anatomy. Because they do not contain polyethylene,
