[Research on the application of anthropometric parameters in predicting the diameter of autologous quadriceps tendon grafts].

Height is an effective predictive factor for the diameter of autologous hamstring tendon grafts. Factors such as gender, age, surgical side, body weight, and BMI are not influential to the diameter of the hamstring tendon grafts. Under the condition of the same height, there is no significant difference in the influence of these factors on the graft diameter. Preoperative physical activity level and the duration of injury do not significantly affect the diameter of the hamstring tendon grafts obtained during surgery. It is recommended to use the formula 'Graft Diamete<i>r</i>=2.636 + 0.029 × Height (cm)' for preoperative prediction.
