Comparison of anterior cruciate ligament perfusion after reconstruction with hamstring autograft in two methods of preservation or isolation of tibial junction based on dynamic contrast enhanced MRI findings of a randomized clinical trial study

Anterior cruciate ligament blood supply after reconstruction with hamstring autograft in two methods of maintaining or isolating tibial junction based on findings dynamic contrast enhanced MRI Is compared

a clinical trial with a control group, with parallel groups, double-blind, approved, on 40 patients. Excel software Rand function was used for scanning.

The present study will be performed in the form of a randomized clinical trial on patients diagnosed with isolated anterior cruciate ligament injury who is a candidate for surgery referred to Shafa Yahyaian Hospital. After the approval of this plan in the ethics committee of the medical school of Iran University of Medical Sciences, and registration in the clinical trial system of the country, written informed consent will be obtained from patients who are eligible to participate in the study.

Inclusion criteria: Patients aged 18-40 years who have suffered ACL isolation following trauma. Exclusion criteria: Knee or leg fractures Simultaneous ligament injury Meniscus damage that needs to be repaired and affects postoperative reflux Trauma to the knee or leg - Clear deformity in the knee or leg History of previous knee or leg surgery

Control group: Patients with ACL tear who undergo ACL reconstruction with complete separation of the hamstring tendons from the distal and proximal. The case group, while the distal attachment of the tendon is preserved, is detached from the proximal and harvested out and reconstructed while maintaining the distal attachment.

Randomization method in the present study: Simple randomization is such that the form is divided among the control and intervention groups once. Randomization unit: will be personal. Visualization layers: Using randomization layers (stratified randomization) Using random options is placed in different groups and image blocks are used for balance in groups The samples are classified according to the center of the class and then in each class with the help of software to generate a random sequence Visualization tool: Random number table How to construct a random sequence is selected one by one Explanation of Concealment of Concealment Allocation: The surgical material and the person performing the analysis are not aware of the type of intervention.

At the time of obtaining informed consent, patients are explained in an understandable language that they will undergo method 1 or 2 in one of these two hospitals. Random patients are operated on in one of two ways. There is no difference between the two methods in terms of preoperative and postoperative programs. There is no difference between the two methods in terms of pre- and postoperative interventions and complications. There is no difference between patients in terms of the appearance of extremity after surgery. There is no difference in preoperative and postoperative rehabilitation between the two groups. The surgeon is aware of the type of surgery, but visit the patient in the same way in both groups.

All variables and all potential data can be shared after identifying individuals

Access period starts 6 months after the results are published

It will be available to researchers working in academic institutions, and people in industry can apply for it.

The data can be reviewed and used to improve clinical conditions and maintain patient health and perform meta-analyzes.
