Robotic-assisted unicompartmental knee arthroplasty is associated with earlier discharge from physiotherapy and reduced length-of-stay compared to conventional navigated techniques

Computer-assisted surgery (CAS) has been used to improve intraoperative accuracy to restore patient’s anatomy and joint kinematics. It is not yet known whether robotic systems provide significant benefits over established navigation techniques. Thirty-one patients underwent robotic-assisted UKA (RA-UKA) over a 14-month period. Length of operation, transfusion requirements, time to discharge, range-of-motion and analgesia requirements were compared to a similar cohort of 31 patients who had received UKA using computer-assisted surgery (CAS-UKA). All patients in the RA-UKA and CAS-UKA groups underwent surgery without conversion to conventional techniques. Both cohorts were similar apart from mean BMI (RA-UKA-group 28.5 vs 32.2; p
