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
