Clinical trial, parallel groups, double-blind, randomized, on 100 patients. In order to randomize, the block randomization method will be used.

Patients requiring simultaneous reconstruction of the anterior cruciate ligament and anterior lateral ligament of the knee who refer to Firoozgar Hospital in Tehran will be included in the study. Patients will be randomly divided into 2 groups based on blocks of 10. Patients, responsible for data collection, analysis and outcome assessment will be blinded.

Inclusion criteria: patients requiring simultaneous reconstruction of the anterior cruciate ligament and anterior lateral ligament of the knee, The age range from 18 to 45 years. Exclusion criteria: Coagulation disorders, Neurological disorders.

Intervention group 1: The reconstruction method of the anterior lateral ligament of the knee will be the modified Limer method. A flap 8 cm long and 1 cm wide is separated from the proximal part and then the free head of the ITB flap will be fixed with a screw without passing under the LCL, after passing through the canal, in about 40 degrees of knee flexion. Intervention group 2: After performing ACL repair surgery, they will undergo ACL reconstruction using the classic Limer method. The free head of the ITB flap will be fixed with a screw by passing under the LCL, with the knee flexed at approximately 40 degrees.

Anterior Cruciate Ligament Rupture

Patients will be randomly divided into 2 groups. The randomization tool will randomize the table of numbers. Block randomization method will be used for randomization. Block randomization is for the purpose of making sure that exactly equal number of participants enter the study groups. The advantages of block randomization are that the balance of the number of participants in each group is guaranteed. For this purpose, 10 blocks will be formed and in each block 5 people from intervention group and 5 people will be placed in the control group. A total of 10 blocks will be considered to reach the sample size. Blocks contain numbers, numbers represent study groups. Their order will be determined by the statistician from the beginning. In order to hide the random allocation, opaque envelopes sealed with a random sequence will be used. In this method, each of the generated random sequences will be recorded on a card and the cards will be placed in the envelopes in order. became. In order to maintain a random sequence, the outer surface of the envelopes is numbered in the same order. Finally, the lid of the letter envelopes is glued and placed in a box. At the time of registration of participants, based on the order of entry of qualified participants into the study, one of the envelopes will be opened in order and the assigned group of that participant will be revealed.

Patients will be aware that they will be randomly assigned to one of the two study groups, but will not know which method will be provided in that group. Patients will be assigned to one of two groups using a random number table. The person in charge of data collection, the analyst and the outcome evaluator will collect and analyze the information based on groups 1 and 2 and will not know the type of treatment in the groups and will be kept blind.
