Table 2 Comparison of IKDC score of knee joint between two groups (points)

Group	Case (n)	Pre-operation	3 months after surgery	6 months after surgery	12 months after surgery
Group M	35	48.29 ± 3.89	80.51 ± 3.62*	87.29 ± 2.71*	93.06 ± 2.52*
Group N	35	49.54 ± 2.87	73.66 ± 3.57*#	81.94 ± 3.40*#	92.37 ± 2.55*
t value	–	−1.537	7.980	7.280	1.133
^#P value	–	0.254	0.000	0.000	0.261

Data was expressed as mean ± SD. * P<0.05 vs. Pre-operation, intragroup comparison; #P<0.05 vs. Group M, intergroup comparison. Group M, patients received remnant-preserved anterior cruciate ligament reconstruction (ACLR) based on modified Crain classification; group N, patients given ACLR with complete clearance of the remnants.
