Abstract:
Unicompartmental knee arthroplasty (UKA) has seen a revival of popularity in the last thirty years in the United States. The benefits of a medial UKA over the previous 'gold standard' for knee osteoarthritis, the total knee arthroplasty, include increased postoperative range of motion (ROM), maintenance of natural knee mechanics, faster recovery, similar pain relief and decreased morbidity. Mobile-bearing UKA (MB-UKA) implants have been developed to improve polyethylene wear while maintaining normal knee kinematics. In this review, we will cover indications and contraindications for aN MB-UKA, patient selection, and technical tips and tricks.
