No report has specifically addressed the question of the influence of gender on outcome following unicompartmental knee arthroplasty (UKA). To clarify this issue, we studied two groups of 40 patients of each gender, matched by pre-operative clinical and radiological presentation, and with post-operative follow up of at least 2 years. The mean age at operation was 71 years and the mean follow-up was 5.9 years. In both groups, IKS score improved significantly, but without difference based on gender. No difference was found between groups in terms of range of motion, alignment, or radiologic progression of arthritis. These results suggest that when utilizing specific patient selection criteria, gender does not influence outcome following UKA.
