The outcomes in the MLPR, FTA, and COP among the preoperative, postoperative, and control groups

Parameters	Preoperative	Postoperative	Control	P-value
Forefoot MLPR	1.48 ± 0.19	1.58 ± 2.0	1.53 ± 0.15	0.146
Rearfoot MLPR	0.83 ± 0.19	1.03 ± 0.16*	1.01 ± 0.21*	0.017
FTA (°)	10.3 ± 4.1	9.2 ± 5.1	9.6 ± 4.7	0.461
AP-COP	137.8 ± 10.4	150.4 ± 11.7	146.5 ± 12.1	0.315
LS-COP	6.3 ± 5.4	-1.2 ± 6.8*	0.2 ± 6.1*	0.031

Data are presented as the mean value ± standard deviation; MLPR, medial-lateral pressure ratio; FTA, foot progression angle; AP-COP, anteroposterior center of pressure; LS-COP, the lateral symmetry of COP (a positive value or negative representing transferring laterally or medially); *compared with preoperative values, P < 0.05
