Introduction: The anterior cruciate ligament (ACL) is an important stabilizing ligament of the knee that is frequently injured in athletes and trauma victims. We aimed to evaluate the correlation between anthropometric measurements of the patients and their graft dimensions. Methodology: This observational study was conducted on 50 patients with ACL injury treated by arthroscopic quadrupled hamstring graft reconstruction at AJ Institute of Medical Sciences and Research Centre, Mangalore between May 2017 and April 2018. Patient related data like age, gender, side involved, symptoms reported, anthropometric measurements, graft length and diameter was replace was with ‘were’ noted. Correlation of graft length and diameter with age and anthropometric measurements was assessed. Results: Mean graft length of all patients was 11.39±1.31 cms, and was significantly higher in male as compared to female patients (11.82 ±0.76 vs 9.13±1.36, p value <0.001). Average graft diameter was 7.24±0.75 cms and was also significantly larger among male patients as compared to female (7.40±0.69 vs 6.38±0.35, p value <0.001). Graft length was found to have a significant inverse correlation with age of the patient (r = -0.39, p value <0.01), significant direct correlation with height (r = 0.71, p value <0.001) and weight (r = 0.29, p value <0.05) of the patients. Diameter of graft used was found to have a significant positive correlation with height of the patients (r = 0.50, p value <0.001). Conclusions: Anthropometric measurements can be used for preoperative planning and to help counsel patients on appropriate graft choices prior to surgery.
