Fig. 2 — The graph shows improvement in the Knee Society score (KSS) with time in both groups. In Group 1, pairwise comparisons revealed statistically significant improvement between each time point from preoperative (preop) period to 6 months after surgery (p<0.001). In Group 2, pairwise comparisons revealed statistically significant improvement between each time point from preop period to 1 year after surgery (p<0.001). The KSS decreased slightly between the 3- to 5-year follow-up in Group 2 although no statistical significance was found.
