The ODI score in the THA→LF group (12.94 ± 3.36) was slightly higher than that in the LF→THA group (11.07 ± 4.93), but the difference only approached significance ( P = 0.075) (Fig. 2 ).
The ODI score in the THA→LF group (12.94 ± 3.36) was slightly higher than that in the LF→THA group (11.07 ± 4.93), but the difference only approached significance ( P = 0.075) (Fig. 2 ).
Additionally, at the last follow-up, the SS in the THA→LF group was significantly higher than that in the LF→THA group ( P = 0.008), while the differences between the two groups for the PT and PI-LL, though not reaching statistical significance, still showed a trend toward difference (PT: P = 0.097; PI-LL: P = 0.085).
Before conducting IPTW, the PI was consistently higher in the THA→LF group compared to the LF→THA group; however, these differences between the two groups did not reach statistical significance (Supplementary Fig. 1 A).
