Comparative study of the clinical efficacy of all-inside and traditional techniques in anterior cruciate ligament reconstruction

Table 1 Comparison of knee International Knee Documentation Committee scores between the two groups

IKDC score	AIST group	TBT group	χ2 value	P value
Grade A	30	24	1.657	0.233
Grade B	11	13
Grade C	1	1

AIST: All-inside quadrupled semitendinosus; IKDC: International Knee Documentation Committee; TBT: Traditional hamstring tendon.

Table 2 Comparison of knee Lysholm scores between the two groups (mean ± SD)

Group	Patient	Preoperative	6 wk postoperatively	12 wk postoperatively
AIST group	42	63.3 ± 5.6	75.3 ± 6.5	86.7 ± 5.8
Group	38	64.6 ± 4.8	74.6 ± 7.1	85.5 ± 6.6
t value		0.765	0.799	0.631
P value		0.365	0.434	0.523

Comparison of the preoperative and 6-wk postoperative scores (t =4.889, P = 0.005); Comparison of the preoperative and 12-wk postoperative scores (t = 11.568, P = 0.005). In the control group, the preoperative and 6-wk postoperative scores were compared [t = 3.121, P = 0.004 (corrected t-test)]. In the control group, the preoperative and 12-wk postoperative scores were compared (t = 9.281, P = 0.005). AIST: All-inside quadrupled semitendinosus.
