Abstract：Objective To investigate the short-term effectiveness of arthroscopic anterior cruciate ligament ( ACL ) single-bundle reconstruction using hamstring tendon allograft with remnant preservation. Methods The clinical data were retrospectively analyzed from 76 patients treated by arthroscopic anterior cruciate ligament reconstruction using hamstring tendon allograft with remnant preservation from January 2013 to December 2015. There were 53 males and 23 females with an average age of 30.4 years ( range: 18 - 51 years ), including 50 cases of left knees, 26 cases of right knees. Fifth-one cases were diagnosed preoperatively while 25 cases during the operation. The disease duration lasted from 2 days to 4.5 years ( mean, 1.3 months ). Rolimeter test, Lysholm scores and international knee documentation ( IKDC ) grading were used for the evaluation before the operation and in the follow up. Results All the 76 patients were followed up for 12 - 34 months ( mean, 19 months ). All incisions healed by the first intention. No fever, infection or rejection reaction occurred. Postoperative synovial fluid appeared in 4 cases, and disappeared after its removal in 2 weeks and conservative treatment. Anterior drawer test was positive in 2 cases. Lachman test was negative in all cases. Lysholm scores were increased from ( 43.4 ± 4.3 ) pre-operation to ( 86.4 ± 6.4 ) post-operation. Seventy-two patients got normal IKDC scores ( 94.74％ ). Larson scores were increased from ( 45.3 ± 5.5 ) pre-operation to ( 85.4 ± 4.8 ) post-operation. Pivot shift test of all patients was negative. Joint range of motion was normal. Conclusions Arthroscopic anterior cruciate ligament reconstruction with remnant preservation is beneficial for the stability of the knee and further recovery, and the short-term effectiveness is satisfied.
