Oxidized zirconium (OxZr) has been introduced as an alternative bearing for femoral components in Total Knee Arthroplasty (TKA). It has a ceramic-like zirconium oxide outer layer with a low coefficient of friction. Early studies have found OxZr TKA to have a low incidence of early failure in young high demand patients. Currently no study has reported on the outcome of these implants beyond ten years. The purpose of our study was to present an in-depth 15-year survival analysis of cemented Profix II OxZr TKA.Abstract
Background
Objectives
To review the outcomes of patients undergoing manipulation under anaesthetic (MUA) after primary total knee arthroplasty (TKA) and predict those that may require such a procedure. We prospectively analysed all patients who required MUA post TKA performed by 2 surgeons using the same prosthesis from 2003 to 2008 and compared them to a control group of primary TKA matched for age, gender and surgeon. All patients in both groups had pre- and post-operative measurements of range of movement. In addition risk factors were identified including warfarin and statin use, diabetes and body mass index.Purpose
