Abstract：Objective: To observe the curative effect of anterior cruciate ligament reconstruction combined with anterior lateral ligament reconstruction on ACL injury with high-grade pivot-shift. Methods: A total of 78 patients with ACL injury admitted to the hospital from October 2015 to January 2018 were enrolled in the study. They were divided into control group and combined group by hierarchical random number table method, 39 cases in each group. The control group was given ACL reconstruction. The combined group was given ACL reconstruction combined with ALL reconstruction.The stability grading, knee range of motion, recovery of muscle strength, change of Lysholm scoring and surgical safety were compared between the two groups. Results: There were no significant differences in stability grading, limited angle of knee flexion, limited angle of knee extension, atrophy index or Lysholm score between the two groups before the surgery (P>0.05). The negative rate in the stability grading of the combined group was significantly higher than that of the control group after the surgery (P<0.05). The limited angle of knee flexion, limited angle of knee extension and atrophy index were significantly decreased in both groups after the surgery, and the above indexes in the combined group was significantly lower than those in the control group (P<0.05). The Lysholm scores of the combined group at 1 month, 3 months and 5 months after surgery were significantly higher than those of control group (P<0.05). There was no significant difference in the total incidence of complications after the surgery between the two groups (P>0.05). Conclusion: ACL reconstruction combined with ALL reconstruction is effective in the treatment of patients with high axially displaced ACL injury. It plays an active role in improving joint stability, knee joint mobility and muscle strength recovery, and has a certain degree of safety.
