Abstract

The purpose of our study was to compare the clinical, functional and radiological results of two types of tibial components for the same total knee prosthesis (posterior stabilized HLS), all-polyethylene (group A) and metal-backed (group B), in order to answer the following question: does use of an all-polyethylene piece affect mid-term outcome of total knee arthroplasty (TKA)? This was a retrospective comparative analysis of a single-center non-randomized consecutive series of 169 patients with an all-polyethylene posterior stabilized cemented gliding TKA. This series was matched with another retrospective series of 169 posterior stabilized cemented TKA with a metal-backed tibial piece. Matching factors were age, gender, etiology, and follow-up. The two series were extracted from our database which included all patients who underwent surgery for a TKA in the same institution (Lyon Civil Hospices) performed by one of the authors (PN) or under his responsibility between 1987 and 1996...
