Fig. 6. Modified Mankin's scores of the sham surgery group (SHAM group), the bilateral ovariectomy group (OVX group), the anterior cruciate ligament transection with medial meniscectomy group (ACLT with MM group), and the bilateral ovariectomy plus anterior cruciate ligament transection with medial meniscectomy group (OVX plus ACLT with MM group). This figure shows significant differences among all groups (**p<0.001). OVX plus ACLT with MM group showed significantly higher modified Mankin's score than the OVX group (*p=0.008) and the SHAM group (*p=0.008). The Kruskal-Wallis test followed by post-hoc Mann-Whitney U test with Bonferroni correction.
