Intra-Articular lesions in Anterior Cruciate ligament Deficient Knees Undergoing Arthroscopic Reconstruction Surgery

Introduction: Anterior ligament cruciate ligament (ACL) injury of the knee is one of the most common injuries to the lower limbs in athletes. The purpose of this study is to investigate knee joint lesions and its related factors in patients with anterior cruciate ligament tear. Methods: This cross-sectional descriptive study was performed on patients with anterior cruciate ligament rupture referring to Imam Sari Hospital from 21/3/2015 until 21/1/2018. Patients’ information such as age, sex, history of injury, surgical history, history of cruciate ligament surgery, height and weight, body mass index(BMI), type of injury, type of exercise and type of cartilage lesions were entered into a study form. Findings: Finally, 100 patients were enrolled in the study, 94% of them were male and the mean age of patients was 30 years. 42% of patients were 20-30 years of age and 25% were 30-40 years old. 72% had meniscal tear in which 64% of patients had rupture of the medial meniscus, and 25% of the lateral meniscus and 11% both menisci..18% of patients suffered from cartilage damage following ACL injury. 64% of injuries were due to sports specially football and 14% were during the work. In this study age and BMI were significantly correlated with the number of injuries. Conclusion: The results of this study showed that the most common activity causing ACL tear is sport specially football and a significant number of injuries occur during work. Athletes have a high probability of recurrent knee injury. Meniscal injury is frequent and more common in chronic cases.surprisingly chondral damages were not common and all were mild.. Also, older age and greater body mass indexes are more associated with recurrent episodes a good predictor of the frequency of ACL injury.
