Predicting four-stranded hamstring graft size using anthropometrics in the Vietnamese population

Background: This research aims to establish a relationship between anthropometric measurements and the dimensions of four-stranded hamstring autografts within the Vietnamese population. Methods: We conducted a cross-sectional study on patients diagnosed with anterior or posterior cruciate ligament ruptures and underwent arthroscopic reconstruction using four-stranded hamstring autografts from September 2020 to September 2022. The investigation examined whether there was a correlation between the gender, height, weight, body mass index, femoral length, or thigh circumference of patients and the dimensions of the grafts. Results: 50 patients (36 males, 14 females, an average age of 32.96 ± 1.46) were included in this study. Weight correlated most significantly with graft diameter, followed by height and BMI. A significantly strong correlation existed between height and graft length, and height was essential in predicting that length. Graft diameter, which strongly correlates with the combination of sex, weight, and height (F = 20.7, R2 = 0.55, p < 0.001) can be predicted by height, weight, or BMI through subsequent linear regression analysis with ­significant values. Conclusions: The dimensions of four-stranded hamstring autografts exhibit noteworthy correlations with anthropometric variables. These statistical relationships offer valuable insights for orthopedic specialists, enabling them to predict graft sizes, enhance planning, and reduce the likelihood of complications during reconstruction.
