Abstract

Hamstring auto graft size is a critical factor in anterior cruciate ligament (ACL) reconstruction outcomes, yet preoperative prediction remains challenging. To evaluate correlations between hamstring auto graft size and patient anthropometric measurements, including height, weight, femur length and body mass index (BMI). This cross‐sectional study included 75 patients undergoing ACL reconstruction. Preoperative anthropometric measurements were recorded and intraoperative graft diameter was measured. Correlations were analyzed using Pearson correlation coefficients and multiple regression analysis. Mean graft diameter was 8.2±0.7 mm. Strong correlations were found between graft diameter and femur length (r=0.701, p<0.001) and height (r=0.642, p<0.001). Weight showed moderate correlation (r=0.483, p<0.001), while BMI showed weak correlation (r=0.312, p=0.006). Multiple regression analysis explained 64.2% of graft diameter variance. Significant gender differences were observed in mean graft diameter (males: 8.4±0.6 mm, females: 7.8±0.5 mm, p<0.001). Femur length and height are the strongest predictors of hamstring auto graft size. The predictive model developed could improve preoperative planning in ACL reconstruction.
