Objectives: Anterior cruciate ligament (ACL) tear is a common sports injury affecting the knee joint in the Middle East and worldwide. Providing an adequate graft is required to prevent revision surgery. This study aims to determine if the body mass index (BMI) can be used as a predictor of the hamstring autograft size. Methods: Data of 48 consecutive patients, who underwent ACL reconstruction using quadruple hamstring autograft technique in the same institute by the same surgeon, were retrospectively reviewed. Skeletally immature patients and those who underwent revision ACL surgeries were excluded. Patients' anthropometric measurements were collected. Quantitative data from the patients' charts were included in the descriptive statistics. Results: The mean age of our cohort was 30.3 ± 6.3 years, with a mean height of 1.7 ± 7.8 m and a mean weight of 81.3 ± 14.6 kg. Mean BMI was 27.8 ± 5, and mean graft size was 7.8 ± 0.5 mm. Results showed that the correlation between the BMI and the autograft size was statistically insignificant. Other variables have no association with the autograft size in the linear regression model. Conclusion: Our study showed no correlation between anthropometric measurements and the autograft size; therefore, these measurements were not able to determine the diameter of the autograft. Further studies looking into thigh diameter and ethnicity and radiological studies with a larger sample size are recommended.
