ObjectiveTo explore the clinical efficacy of arthroscopic internal tension-relieving technique for reconstruction of anterior cruciate ligament of knee joint. MethodsEighty-four patients with anterior cruciate ligament fracture were selected and randomly divided into tension-relieving group or control group, with 42 cases in each group. The anterior cruciate ligament was reconstructed by arthroscopic internal tension-relieving technique in the tension-relieving group, and by arthroscopic anatomic single bundle in the control group. The changes of range of motion in knee joint, Hospital for Special Surgery (HSS) knee score, and 12-item Short Form Health Survey (SF-12) were recorded and compared before and after treatment. ResultsAfter treatment, the range of motion in knee joint, HSS score, and SF-12 scores increased in both groups, and were higher in the tension-relieving group than in the control group (all P＜0.05). ConclusionReconstruction of anterior cruciate ligament through arthroscopic internal tension-relieving technique can significantly increase the range of motion in knee joint, improve knee joint function, and enhance significantly the life quality of patients. It is worthy of clinical application and promotion.
