OPN: Is polyethylene hip resurfacing something we will be seeing on the UK market in the near future? Ronan Treacy: Given the frequency of these custom-based referrals, we found ourselves disappointing several patients and interested surgeons with our inability to supply the custom implants more freely. We are being very circumspect with our introduction of this new technology. Derek McMinn: We have just over three years of experience with the custom metal-on-crosslinked polyethylene resurfacing. Clinical and radiographic results are excellent and there have been no revisions.
