Alnachoukati O, et al. - This study sought to offer the first long-term, large patient sample size, Oxford phase III multi-site survivorship study in the United States, investigating patient-reported outcomes of pain and function and in-depth analysis of causes for revision, along with addressing recent advancements that can help aid the UKA process and further improve partial knee survivorship. The findings of this first large-scale, ten-year, multi-site follow-up of the Oxford mobile-bearing medial UKA undertaken in the United States, revealed good survivorship and excellent patient outcomes.
