Anthropometric parameters measurement to predict 4-strand hamstring autograft size in single bundle anterior cruciate ligament reconstruction of South Sulawesi population

Abstract

ABSTRACT Introduction: Among many available autograft options for anterior cruciate ligament (ACL) reconstruction, hamstring tendon (HT) is the most popular graft. The ability to identify whether patient is at risk of inadequate HT autograft size prior to surgery is very important. Among some methods that have been done, anthropometric parameters are considered as an easy and cost effective method in predicting the size of HT autograft. In order to predict the length of semitendinosus tendon (ST), gracilis tendon (GT) and quadrupled HT graft diameter, a prospective study was conducted to determine the anthropometric parameters. Method: Anthropometric parameters, including age, gender, height, weight, body mass index (BMI), true leg length (TLL), thigh circumference and thigh length of 60 patients with primary ACL reconstruction was measured before surgery. Using univariate analysis, independent-sample t -test, Pearson correlation test, and simple logistic regression to evaluate the correlation of these anthropometric variables on the size of the graft obtained. Result: Average values for GT length (23.17 ± 3.01 cm), ST length (24.93 ± 2.85 cm), and 4-strand HT autograft diameter (7.36 ± 0.66 mm). 83.33% total patients had graft diameter of 7 mm and more. Height and TLL correlate to GT length and quadruple HT autograft diameter, while thigh circumference correlates to ST length. Conclusion: Height and TLL can be predicting factor of GT length and quadruple HT autograft, while thigh circumference to ST length. Patients who are less than 155 cm in height and less than 76 cm in TLL are at risk of having 4-strand HT autograft diameter less than 7 mm. Highlights:
