Objective  To investigate the relationship between the vertical distance from semitendinosus insertion to tibial plateau (S-T) and the physical characteristics of patients, in order to provide reference for incision design to expose the semitendinosus insertion. Methods  The patients with ligament injury who underwent primary anterior cruciate ligament reconstruction between January 2022 and December 2022 were selected as the research subjects. The patients’ baseline data were collected, including age, gender, height, and body mass. During reconstruction operation, the S-T was measured. Considering the S-T as the dependent variable and baseline data as the independent variable, multiple linear regression analysis was used to establish a regression equation to determine the possible influencing factors of semitendinosus insertion location. Results  According to the selection standard, a total of 214 patients were enrolled, including 156 males and 58 females, aged (27±9) years (14-49 years), with a height of (174.7±6.8) cm (range, 160-196 cm) and a body mass of (73.43±12.35) kg (range, 53-105 kg). The S-T was (56.36±3.61) mm (range, 47-67 mm). The multiple linear regression analysis results showed that the height was positively correlated with S-T (β=0.407, SE=0.055, t=7.543, P<0.001); the regression equation was S-T=−14.701+0.407×height, R2=0.690. Conclusion There was a linear relationship between the height and semitendinosus insertion. The location of semitendinosus insertion estimated by the formula (S-T=−14.701+0.407×height) is reasonable, which provides a theoretical basis for rapid, accurate, and safe location of semitendinosus insertion and design of surgical incision in clinic.
