Sir,
We read this article with interest.
Before patients consent to hip resurfacing it is important to explain to them that as yet we do not know the long-term outcome of the prosthesis.1 Patients often assume that revision of a failed hip
resurfacing is a straightforward procedure and that the outcome will be the same as that of a conventional primary total hip replacement.
The authors state that “when assessing a new prosthesis, examination of those which have failed is often more instructive than discussing survivors”. Therefore the results of the revision procedures in the three failures achieve paramount significance. Although the authors discuss the mechanism of failure including
infection in two and subcapital fracture in another patient, they do not discuss the outcome.
We would be interested to know the fate of the three patients who underwent revision procedures and
whether their follow-up, albeit short, was comparable with that of a
conventional primary hip replacement?
