	Traditional group	*P value*	Laser group	*P value*
Anatomic angle	Preoperatively	24 months	Preoperatively	24 months
MPTA (°)	81.03 ± 2.36	91.14 ± 3.05 0.00	81.25 ± 1.61	90.89 ± 2.98 0.00
FTA (°)	181.17 ± 3.15	172.63 ± 2.57 0.00	180.31 ± 2.72	172.67 ± 2.76 0.00
PSA (°)	8.46 ± 0.62	10.07 ± 0.67 0.00	8.47 ± 0.39	10.58 ± 0.78 0.00

The medial proximal tibial angle (MPTA), femoral tibial angle (FTA), and posterior slope angle (PSA) were significantly corrected after 24 months in both groups (P = 0.00)
