Table 2 Comparison of Harris Hip Score (HHS) between subtrochanteric osteotomy (SO) and low femoral neck osteotomy (LRNO) groups over time.
| Time point | SO (n=36) | LRNO (n=37) | P value |
|---|---|---|---|
| Preoperative | 39.14±3.34 | 38.86±3.97 | 0.750 |
| 1 month | 50.64±2.59 | 57.89±4.02 | 0.000 |
| 3 months | 65.39±2.27 | 74.16±3.46 | 0.000 |
| 6 months | 84.14±3.19 | 83.78±3.48 | 0.651 |
| 12 months | 87.81±3.24 | 87.95±3.37 | 0.857 |
| Data presented as mean±SD. Higher HHS scores indicate better function (range 0–100). Statistical analysis: independent test was used for group comparisons. | |||
