Abstract

Rupture of the anterior cruciate ligament (ACL) disturbs the stability of the knee, and increases the risk of subsequent meniscal damage and the risk of developing degenerative joint disease. Surgical ACL reconstruction (ACLR) is one of the most common orthopedic surgeries. This study aimed to investigate the effective factors on the rehabilitation rate in ACLR with hamstring autograft based on the Tegner activity scale (TAS) and Lysholm knee scoring scale (LKS) one year after the operation. In this descriptive-analytical study, 140 patients who underwent ACLR surgery with hamstring autograft were evaluated. Patients were evaluated based on TAS and LKS scores before and after the surgery and their responses were recorded. Then, the rehabilitation rate was calculated based on these two scales, and the association between the rehabilitation rate and pre-operative and post-operative parameters was investigated. Based on the findings, LKS scores after surgery were significantly associated with age, gender, education, injury mechanism, loss of full flexion ROM, analgesic consumption after surgery, surgical site infection, and BMI. Also, the LKS score was higher in people whose Tegner activity scale score was 8 before the injury. There was no significant association with smoking before surgery, hematoma at the graft site after surgery, knee meniscal lesions, and hemarthrosis formation during the first six hours of ACL injury. Determining the effective factors before and after surgery on the rehabilitation rate of patients undergoing ACLR who were treated with hamstring autograft may be useful in evaluating the rehabilitation rate of patients‎.
