Improved Posterior Slope of the Tibial Component in Unicompartmental Knee Arthroplasty Using an Offset Adjustment Method

= 0.009). Fewer outliers with PTS changes of 2 degrees or more were observed in the offset adjustment group. Using an offset adjustment jig in UKA significantly improves the reproducibility of patient-specific PTS, reducing deviations and potential biomechanical issues. This method is practical, cost-effective, and compatible with various implant models, offering a reliable solution for achieving precise PTS alignment without extending surgical time.
