Femoral width (millimeters)^a

Changes in femoral width (P Value)**
IM po-op vs Pre-op^a	10.5 ± 0.5 (p < 0.001)
FU vs Pre-op^a	7.8 ± 5.6 (p < 0.001)
IM po-op vs FU^a	2.5 ± 4.8 (p = 0.002)

Pre-op Preoperative, IM po-op Immediate postoperative, FU Ten years of follow-up
^aSkewed distribution data are presented as medians with interquartile ranges
**The changes in femoral width were calculated by subtracting the latter from the former. The data were normally distributed and are presented as the mean ± standard deviation. P values were analyzed with t tests
