Assessing medium term outcome of medial Uni compartmental replacement and whether there is a difference in outcome between mobile and fixed bearing variants of the same prosthesis. Knee outcome was assessed in 150 patients (81 male, 69 females, mean age 67.0±10.4yrs) undergoing medial UKR knee (Uniglide, Corin Medical, UK) using either fixed or mobile bearing prosthesis between 2002-2007. All operations were performed by members of the Bristol knee group. All patients were scored using the American Knee Score (AKS), Oxford Knee Score (OKS), and WOMAC pre-operatively and at 2-year follow up. The mobile group (n=93) comprised 43 males and 50 females, aged 62.8±8.9yrs. The fixed bearing group (n=57) comprised 38 males and 19 females, aged 74±8.8yrs.Purpose of the study
