Adding to the debate about bearing surfaces, a team from St Michael’s Hospital in Toronto studied 102 hip replacements in 91 patients randomised to receive either a cobalt-chrome on ultra-high molecular weight polyethylene (UHMWPE), cobalt chrome on highly cross-linked polyethylene (HXLPE), or a ceramic-on-ceramic bearing. All patients received a Smith and Nephew Synergy uncemented stem and a Reflection uncemented acetabular component. Bearings were 28mm cobalt-chrome heads with UHMWPE, HXLPE or ceramic-on-ceramic. 87 patients were available for five year review.
