High return to sport rate in patients undergoing image-based robotic arm assisted unicompartmental knee arthroplasty.

Patients undergoing RA-UKA showed a 93.1% RTS rate after surgery. Differences were detected in terms of postoperative UCLA and FJS-12 scores between patients who performed and who did not practice sport activities after surgery. High levels of postoperative UCLA scores were associated with higher KOOS-JR and patients' satisfaction.
