Signal/noise quotient values of the tibial ends of the grafts

Postoperative time	Platelet‐rich plasma group	Normal saline group	P‐value *
3 months	7.33 ± 4.28	9.81 ± 2.84	0.04
6 months	9.13 ± 5.79	12.26 ± 4.26	0.04
12 months	8.11 ± 4.31	10.41 ± 7.50	0.02
P‐value †	0.03	0.01

^* P < 0.05 indicates a statistically significant difference in signal/noise quotient values between the platelet‐rich plasma group and normal saline groups.

^† P < 0.05 indicates a statistically significant difference in signal/noise quotient values at 6 months after surgery compared with the corresponding at 3 and 12 months after surgery.
