Brief Summary

Background: Arthroscopic anterior cruciate ligament(ACL) reconstruction is so far the gold standard for the treatment of ACL ruptures, but this technique still suffers from problems of tendon-bone healing, bone tunnel enlargement, bone resorption, a low rate of return to motion,etc. In recent years, due to the innovation of medical materials and surgical techniques, anterior cruciate ligament repair technology has returned to the field of vision of clinical doctors. This technique has the advantages of preserving the natural ligaments and their proprioceptive sensation, avoiding the bone injury of the tunnel and the complications of the donor site. However, there is still a lack of high-quality clinical randomized controlled trails to provide evidence of the effect of arthroscopic ACL repair. Hypothesis: Arthroscopic ACL repair is comparable to ACL reconstruction in patients with ACL tears (Sherman grades I and II). Study Design: This study was a prospective, multicenter, randomized, double-blinded, parallel-controlled, non-inferiority trial design. A total of 330 patients with ACL tears were randomly divided into 2 groups, and were randomly assigned to the experimental group (arthroscopic anterior cruciate ligament repair) and the control group (arthroscopic anterior cruciate ligament reconstruction) according to 1:1. Follow-up knee function and other scores were performed at 3 months, 6 months, 1 year, and 2 years after surgery, and the total study time is expected to be 3 years.

Outcome Measures

Primary Outcomes (1)

  • IKDC score

    The IKDC is a patient-completed tool, which contains sections on knee symptoms (7 items), function (2 items), and sports activities (2 items). Scores range from 0 points (lowest level of function or highest level of symptoms) to 100 points (highest level of function and lowest level of symptoms). Efficiency of 1 year after operation=Sum of Items/Maximum Possible Score \*100

    1 year

Secondary Outcomes (3)

  • IKDC score

    3 months

  • IKDC score

    6 months

  • IKDC score

Interventions

ACL RepairPROCEDURE

Patients are undergoing arthroscopic anterior cruciate ligament repair. The native ACL is repaired using very strong sutures. This device is used to repair the native ACL and restore knee stability.

ACL Repair

Patients are undergoing arthroscopic anterior cruciate ligament reconstruction. The torn ligament is removed and replaced with a band of tissue that usually connects muscle to bone. The graft tendon is taken from another part of your knee or from a deceased donor.
