IRCT20110809007274N17 IRCT 2022-02-10 Rasht University of Medical Sciences full weight bearing immediately after surgery and Partial weight bearing in the first month in anterior cruciate ligament rupture Evaluation of full weight bearing results immediately after surgery compared with Partial weight bearing in the first month after surgery in patients with anterior cruciate ligament rupture: A randomized clinical trial 2022-01-25 anticipated 84 Complete https://irct.ir/trial/61303 interventional Randomization: Randomized, Blinding: Double blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: In this study estimated sample size is 84 patients and randomization will be applied using random block design (block size: 4, via online Random allocation software). So, 21 quadruple blocks will be obtained and 42 patients will be in group A and 42 patients in group B. List of patients is kept in orthopedic research center in a sealed envelope and will be read daily after the study begins, Blinding description: In current Double-Blind randomized clinical trial, patients are unaware about when and how to weight bearing. Also, evaluating researcher will be different from the person doing the study intervention. Two orthopedic assistants will be used for this purpose. 3 Anterior Cruciate Ligament (ACL) rupture. Intervention 1: Intervention group: Full weight bearing immediately after surgery. Intervention 2: Control group: Partial weight bearing in the first month after surgery in patients with anterior cruciate ligament rupture. Undecided - It is not yet known if there will be a plan to make this available Justification or reason for indecision in sharing IPD is Due to the uncertainty of providing the necessary conditions (such as patient cooperation)
