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.
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.
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 (=0.407, =0.055, =7.543, <0.001); the regression equation was S-T=-14.701+0.407×height, =0.690.
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.
探讨半腱肌止点至胫骨平台的垂直距离（S-T）与患者身体特征之间的关系，为显露半腱肌止点的切口设计提供参考。
选取2022年1月至2022年12月期间接受初次前交叉韧带重建的韧带损伤患者作为研究对象。收集患者的基线数据，包括年龄、性别、身高和体重。在重建手术过程中，测量S-T。以S-T为因变量，基线数据为自变量，采用多元线性回归分析建立回归方程，以确定半腱肌止点位置的可能影响因素。
根据入选标准，共纳入214例患者，其中男性156例，女性58例，年龄（27±9）岁（14 - 49岁），身高（174.7±6.8）cm（范围160 - 196 cm），体重（73.43±12.35）kg（范围53 - 105 kg）。S-T为（56.36±3.61）mm（范围47 - 67 mm）。多元线性回归分析结果显示，身高与S-T呈正相关（=0.407，=0.055，=7.543，<0.001）；回归方程为S-T = -14.701 + 0.
