Neufeld ME, et al. - This study, including minimum 10-year follow-up, provides information regarding the survivorship and functional outcomes of mobile (MB) vs fixed-bearing (FB) unicompartmental knee arthroplasty (UKA). In terms of survival and functional outcomes, the MB and FB designs afforded similar results. In addition, data showed that one-third of revisions needed either stems or augments, all were the MB design.
