Abstract

AbstractPurposeThe impact of gender on the outcomes of unicompartmental knee arthroplasty (UKA) remains a topic of active discussion with limited exploration thus far. The study aims to elucidate the gender effect on clinical outcomes, complications, pre‐ and postoperative radiological outcomes following the implantation of a medial UKA at mid‐term follow‐up in a large section of patients.MethodsThis was a single‐centre, retrospective cohort study encompassing patients undergoing medial UKA between 2011 and 2019. The International Knee Society (IKS) Knee and Function score, patient satisfaction, complications, revisions, pre‐ and postoperative radiological outcomes (coronal plane alignment, femoral and tibial component positioning, posterior tibial slope) were evaluated. Survival rate at the time of the last follow‐up was also recorded.ResultsOf the 366 knees that met the inclusion criteria, 10 were lost to follow‐up, accounting for a 2.7% loss. Mean follow‐up was 5.2 ± 2 years [2.1–11.3]. Out of the total population, 205 patients were females (57.6%, 205/356) and 151 were males (42.4%, 151/356). Men exhibited superior pre‐ and postoperative IKS function scores (p = 0.017). However, no significant differences were observed between women and men regarding improvements of IKS Knee and Function scores, radiographic outcomes and implant survivorship.ConclusionAt a mean follow‐up of 5 years, this study revealed no significant impact of gender on clinical outcomes and complications in patients undergoing medial UKA. Furthermore, no significant differences were evident in radiographic outcomes, implant positioning and knee phenotype.Level of EvidenceLevel III.
