Introduction

Medial unicompartmental knee arthroplasty (UKA) has become an established alternative to total knee arthroplasty (TKA) for isolated medial compartment osteoarthritis, offering faster recovery and better functional outcomes. However, results during the early phase of institutional adoption may vary depending on surgeon experience and procedural standardization. This study aimed to evaluate early clinical outcomes, complication rates, revision profiles, and the learning curve associated with the initial institutional adoption of medial mobile-bearing UKA in a high-volume, multi-surgeon center.

Methods

This prospective case series included 154 consecutive medial UKAs performed by five surgeons on 152 patients. Pre- and postoperative KOOS and NPRS were recorded up to a 24-month follow-up, with a 100% follow-up rate. The primary endpoint was improvement in pain and function as measured by NPRS and KOOS. Inclusion/exclusion criteria, surgical technique, and rehab protocol were standardized.

Results

Mean NPRS improved significantly from 7.6 ± 1.4 preoperatively to 1.8 ± 1.9 at 24 months (p < 0.001). Total KOOS increased from 31.0 ± 12.5 to 88.0 ± 13.4 (p < 0.001), with all subscales exceeding the minimal clinically important difference. The two-year revision-free survival rate was 94.8% (95% CI 90.5–97.0%). A total of 9 complications (5.8%) occurred, mostly early technical events related to the initial learning curve, including three bearing dislocations.

Conclusion

Medial UKA showed excellent early outcomes with a low revision rate and a complication profile consistent with the expected early technical learning phase. These findings support the safe and effective institutional introduction of medial UKA, emphasizing the importance of structured training and standardized protocols for successful early adoption.
