Detailed Description
This is a prospective randomized, controlled, single-center clinical trial study on ACL reconstruction surgery technique. In this study, 60 patients with ACL rupture were recruited according to the enrollment criteria. The recruited patients were randomly divided into groups. The ratio of the control group is 1:1. In this study, 30 patients with ACL rupture in the experimental group will be treated with all-inside reconstruction technique, and 30 patients with ACL rupture in the control group will be treated with complete tibial tunnel technique. All operations will be performed with 4-strand autologous semitendinosus tendon. All fixations will be performed using an adjustable cortical suspensory system. After reconstruction, all subjects will participate in the collection of clinical function scores including Marx Activity score, IKDC score, and clinical evaluation including physical examination, joint laxity, CT and MRI imaging analysis.
