Abstract：
OBJECTIVE: This study aimed to determine the correlation between the intraoperative diameter of double-stranded peroneus longus tendon (2PLT) and length of the PLT autograft and preoperative ultrasound (US) measurements, as well as radiographic and anthropometric measurements. The hypothesis was that US can accurately predict the diameter of 2PLT autografts during operation.
METHODS: Twenty-six patients underwent ligament reconstruction with 2PLT autografts were included. Preoperative US was used to calculate the in situ PLT cross-sectional area (CSA) at seven levels (0, 1, 2, 3, 4, 5, 10 cm proximal to the harvest start point). Femoral width, notch width, notch height, maximum patellar length, and patellar tendon length were determined on preoperative radiographs. Intraoperative measurements of PLT were made, including all fiber lengths of PLT and diameters of 2PLT using sizing tubes calibrated to 0.5 mm.
RESULTS: CSA at 1 cm proximal to the harvest site had the highest correlation with the diameter of 2PLT (r = 0.84, P < 0.001). Calf length had the highest correlation with PLT length (r = 0.65, P < 0.001). The diameter of the 2PLT autografts could be predicted by the following formula: 4.6 + 0.2 × [sonographic CSA of PLT at 1 cm level]; the length of PLT could be predicted by the following formula: 5.6 + 0.5 × Calf length.
CONCLUSIONS: The diameter of 2PLT and length of PLT autografts can be accurately predicted by preoperative US and calf length measurements, respectively. Accurate preoperative prediction of the diameter and length of autologous grafts can provide the most suitable and individualized graft for patients.

摘要：
目的：本研究旨在确定双链腓骨长肌腱（2PLT）的术中直径与自体PLT的长度和术前超声（US）测量值之间的相关性，以及射线照相和人体测量。假设US可以准确预测手术期间2PLT自体移植物的直径。
方法：纳入26例自体2PLT韧带重建患者。术前US用于计算七个水平（收获起点近0、1、2、3、4、5、10cm）的原位PLT横截面积（CSA）。股骨宽度,缺口宽度,缺口高度,最大髌骨长度,术前X线片确定髌腱长度。术中测量PLT,包括所有纤维长度的PLT和直径的2PLT使用上浆管校准到0.5毫米。
结果：采收部位近1cm处的CSA与2PLT直径的相关性最高（r=0.84，P<0.001）。小腿长度与PLT长度的相关性最高(r=0.65,P<0.001)。2PLT自体移植物的直径可以通过以下公式预测：4.60.2×[1cm水平的PLT超声CSA]；PLT的长度可以通过以下公式预测：5.60.5×小牛长度。
结论：通过术前US和小腿长度测量可以准确预测2PLT的直径和PLT自体移植物的长度，分别。术前准确预测自体移植物的直径和长度可以为患者提供最合适和个性化的移植物。
