Crawford DA, et al. - High activity patients were compared to low activity patients regarding implant survivorship and outcomes after unicondylar knee arthroplasty (UKA). Highly active patients had no increased risk of revision after UKA with the Oxford mobile bearing knee at 5-year minimum follow-up. Four hundred eighty-seven patients (576 knees) who underwent UKA with the Oxford mobile bearing knee (Zimmer Biomet, Warsaw, IN) with 5-year minimum follow-up were divided into two groups: Low activity (LA) (UCLA ≤6) and high activity (HA) (UCLA ≥ 7). They observed significantly higher improvements in knee society scores and pain post-operatively in HA group with no increased risk of revision after UKA at 5-year minimum follow-up.
