Perform the preoperative measurement of the hamstring tendons using ultrasound imaging, validating and correlating the measured value with that found during surgical reconstruction of the ligament. A cross-sectional study was carried out with 24 patients who underwent ultrasonographic measurement of the semitendinosus and gracilis muscle tendons and were subsequently submitted to surgical reconstruction of the ACL, with ipsilateral semitendinosus and gracilis tendon grafting. The patients’ ages ranged from 16 to 43 years, with a mean of 24.8 years (SD=8.4 years), 79.2% were men, and the distribution by side was 41.7% right knees and 58.3% left knees. A non-significant correlation coefficient was found between the area calculated by ultrasound (2×semitendinosus area+2×gracilis area) and the intraoperative measurement (r=0.16; p=0.443). No evidence of a difference between intraoperative measurements
