About this study

Official title: A Randomized, Controlled, Multi-center Clinical Trial of the Round-tunnel and Flat-tunnel Technique of Anterior Cruciate Ligament (ACL) Reconstruction

This study intends to perform round-tunnel and flat-tunnel ACL reconstruction technique in 144 patients, and compare the clinical outcomes of the two surgical procedures through follow-up.

Read the detailed description

This is a prospective randomized, controlled, multi-center clinical trial study on ACL reconstruction surgery technique. It is jointly undertaken by the Peking University Third Hospital, Nanjing Drum Tower Hospital, Zhengzhou Orthopaedic Hospital, and Shenzhen Second People's Hospital. Peking University Third Hospital is the team leader unit. In this study, 144 patients with ACL rupture were recruited according to the enrollment criteria. Among them, 54 patients with ACL rupture were recruited and carried out by the Peking University Third Hospital. The recruited patients were randomly divided into groups. The ratio of the control group is 1:1. Each of the other three hospitals recruited 30 patients and randomly grouped them according to the same enrollment criteria. The ratio of the experimental group to the control group was also 1:1. In this study, 72 patients with ACL rupture in the experimental group will be treated with flat-tunnel reconstruction technique, and 72 patients with ACL rupture in the control group will be treated with round-tunnel technique. All operations will be performed with autologous hamstring tendons. After reconstruction, all subjects will participate in the collection of clinical function scores including Tegner score, Lysholm score, IKDC score, and clinical evaluation including physical examination, joint laxity, CT and MRI imaging analysis to verify ACL Advantages of flat-tunnel technique.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • round tunnel techniqueProcedure or surgery

    Both the femoral tunnel and tibial tunnel were drilled by 8-mm cannulated drill

  • flat tunnel techniqueProcedure or surgery

    Both the femoral tunnel and tibial tunnel were dimension of 5×11-mm rounded-rectangular, which was created by initially drilling a round tunnel with a 5-mm cannulated drill and reshaped by use of a bone rasp and custom-made dilator.

Questions about this trial

What is this clinical trial studying?

A study testing round tunnel technique and flat tunnel technique in people with Anterior Cruciate Ligament Rupture, run by Peking University Third Hospital.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 8 Jul 2021. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

KT-2000 (time frame: 6 months, 12 months, 24 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Jul 2021.
