Summary: The ability to accurately predict the length and the diameter of the hamstring tendons [semitendinosus (ST) and gracilis (G)] used in ACL reconstruction continues to be an important factor in decision making and in choosing the best surgical technique and proper graft.

Abstract:

Background

Preoperative estimation of the length and diameter of the semitendinosus tendon (ST) and gracilis (G) can assist and enable surgeons have the opportunity to choose alternative graft. OBJETIVE: The aim of this study was to investigate whether there is correlation between anthropometric measurements such as height, weight, body mass index, age and sex of the patient with the thickness and the length of ST and G tendons. MATERIALS AND METHODS: Between June 2012 and August 2013, data from 64 patients who underwent the surgical procedure of reconstruction of the anterior cruciate ligament, using as the graft tendons of ST and G muscles. The variables collected were age, sex, weight, height and body mass index (BMI), length and diameter of the tendons of muscles ST and G. RESULTS: There was a positive correlation between the height and overall diameter of the graft quad (r = 0.254; p= 0.043), total length of the tendon ST (r= 0.450; p<0.01), diameter double ST (r= 0.270; p= 0.031), ST triple (r= 0.347; p= 0.005), tendon length L (r= 0.249; p= 0.047) and the diameter of the double-G (r= 0.258; p= 0.039). However, age (r= -0.015; p= 0.908), weight (r= 0.165; p= 0.193) and body mass index (r= 0.012; p= 0.926) showed no correlation. CONCLUSION: Our results show that height had a positive correlation with the total length of the flexor tendons and the diameter of the graft flexor (ST and G), while age, weight and BMI did not correlate with the diameter and length of the graft.
