The distribution of resection extent differed significantly between groups (p < 0.001, χ 2 test), with a clear trend toward more radical resections in Group 2 (Cochran–Armitage trend test, p < 0.001).

The preoperative functional status was comparable between groups, and the minor difference in the proportion of KOOS I–II patients (0.4% vs 10.1%) did not reach statistical significance (p = 0.08, Fisher's exact test).
