About

This study intends to perform an all-inside and complete tibial tunnel ACL reconstruction technique in 80 patients, and compare the clinical and radiological outcomes of the two surgical procedures through follow-up.

Full description

This is a prospective randomized, controlled, single-center clinical trial study on ACL reconstruction surgery technique. In this study, 80 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, 40 patients with ACL rupture in the experimental group will be treated with all-inside reconstruction technique, and 40 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.

Enrollment: 71 patients

Sex: All

Ages: 18 to 45 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

Exclusion criteria

• Patients who have not signed informed consent;
• Patients undergoing any additional concomitant ligament repair or reconstruction at the same surgery

71 participants in 2 patient groups

All-inside technique

Experimental group

Description:

Both of the femoral and tibial tunnel will be drilled in a retrograde manner using flip-cutter and femoral and tibial sockets will be created. Graft will be passed from the portal. Adjustable suspensory cortical fixation both on tibial and femoral side will be used.

Treatment:

Procedure: Anterior Cruciate Ligament Reconstruction

Complete tibial tunnel technique

Active Comparator group

Description:

Femoral tunnel will be drilled in an inside-outside manner using standard technique. Then the tibial tunnel will be drilled completely. Graft will be passed from the tibial tunnel. Adjustable suspensory cortical fixation both on the tibial and femoral side will be used.

Treatment:

Procedure: Anterior Cruciate Ligament Reconstruction
