Predicting the peroneus longus tendon autograft size in ACL reconstruction by using anthropometric parameters: A study in South Sulawesi population

INTRODUCTION: Some literature use peroneus longus tendon (PLT) as the alternative to anterior cruciate ligament (ACL) reconstruction to overcome inadequate autograft size potential risk by using hamstring tendon (HT) autograft. Among the available methods to predict PLT measurements, anthropometric parameters are one of the most accessible and feasible methods. The objective of this prospective study was to predict the PLT autograft sizes in single bundle ACL reconstruction by using preoperative anthropometric measurement. METHOD: Anthropometric parameters, including age, gender, height, weight, body mass index (BMI), true leg length (TLL), shank circumference and shank length of 20 patients with primary ACL reconstruction was measured before surgery. Univariate analysis, independent-sample t-test, Pearson correlation test, and logistic regression to evaluate the influence of these anthropometric variables on the diameter and length of the PLT autograft obtained. RESULT: Pearson correlation test has shown that body weight and height correlates to PLT length and diameter also autograft's length and diameter significantly (p < 0.05). The linear regression analysis showed that height, weight, TLL and shank length were signifcantly related to autograft diameter. While height and TLL were significantly related to autograft length. CONCLUSION: Height, weight, TLL and shank length can use to predict PLT autograft diameter. While height and TLL can use to predict PLT autograft length.
