Demographic and radiographic parameters were measured, including pre-operative and post-operative anatomical femorotibial angle (aFTA), posterior tibial slope (PTS), and anatomical medial proximal tibial angle (aMPTA). Multivariate logistic regression analysis was applied to figure out risk factors.<h4>Results</h4>The mean follow-up time was 14.0 years. There were 32 failures categorized into implant loosening (n = 11), osteoarthritis progression (n = 7), insert wear (nBMC musculoskeletal disordersSurvivorship of the fixed-bearing medial unicompartmental knee arthroplasty: mean 14-year follow-up in a single medical center.PMC11010285CORPG3H0701Chang YHLin YCHung KTShih HNLee SHChen CCHsieh PHChang CHHu CCfalseSurvivorship of the fixed-bearing medial unicompartmental knee arthroplasty: mean 14-year follow-up in a single medical center.<h4>Background</h4>This study aimed to report the long-term survival of fixed-bearing medial unicompartmental knee arthroplasty (UKA) with a mean of 14-year follow-up, and to determine possible risk factors of failure.<h4>Methods</h4>We retrospectively evaluated 337 fixed-bearing medial UKAs implanted between 2003 and 2014.
