DM: To monitor this unproven concept as closely as we could,we took the precaution to embed RSA marker beads in the implants, and to seek consent from a small group of recipients to be part of our post implantation vigilance by undergoing RSA analysis as part of the follow up. RT: The 14th National Joint Registry report(NJR) notes a significant reduction in the use of Hip Resurfacings (less than 1per cent) and subsequently the increase in the use of traditional hip replacements in the younger active patient groups.

In the patients who are under the age of 50 years with a diagnosis ofPrimary Osteoarthritis, women have a 99 per cent implant survivorship at 20years, just ahead of men with a 98.5 per cent implant survivorship at 20 years. OPN: Why do you believe these noticeable differences in women occur? Radiological assessment at that time showed11 (3.5 per cent) femoral and 13 (4.1 per cent) acetabular radiolucencies which we believe may be because of stress shielding at the acetabular component to host bone interface. The future of hip joint implants “Technology is always advancing,” says Dr. Hansen. OPN: The hip resurfacing surgeon community is relatively small and close-knit, is there any combined resurfacing registry data that can support the continued use of the hip resurfacing procedure? Of interest is the cases of revision of failed metal-on-metal resurfacings and the use in patients with proven nickel sensitivity. At that time its attention was directed towards the development and distribution of the Birmingham KneeReplacement (BKR) which I am now proud to say holds an ODEP 7A rating and outstanding survivorship and PROMS scores. RT: This is a difficult question to answer definitively. –A study comparing data from the American Joint Replacement Registry with national registry data from other countries found that cementless stem fixation with the use of ceramic and 36-mm heads was the current US preference, while non-US registries indicated that cemented implants and metal and 32-mm heads were used most commonly.2, Opioid Use DM: Uncemented total hip replacement cups use a porous coated metal shell and a highly crosslinked polyethylene liner. The McMinn team presented, ‘High incidence of nickel sensitisation at 10 years: A review of metal-on-metal arthroplasty.’ Pre-revision testing of metal-on-metal resurfacings for metal allergies revealed 75 per cent of these patients tested positive to nickel. OPN: Thank you, we look forward to following your progress. Results for 111 patients who were evaluated using the new spinal function assessment were compared with a matched group of 111 patients who were not evaluated using the system. RT: Being aware of the guidance provided by the MHRA on the use of custom-made orthopaedic implants, coupled with the high production costs of such components, led us to the conclusion that the only viable route for us would be one of developing our own commercial route to progress a highly crosslinked polyethylene hip resurfacing system, in much the same way we achieved with the BHR during the MMT era. Our results were fascinating. Patients with hip arthritis have difficulty walking, climbing stairs and performing routine daily activities.
