本研究的目的是比较两种不同的方法连接肌腱之间的受体和供体肌腱的屈肌腱移植的相似和不同的大小。取犬趾深屈肌腱（FDP）和腓骨长肌腱（PL），分为4组。我们比较的修复技术是阶梯切割（SC）缝线和Pulvertaft编织（PW）。FDP肌腱的直径明显大于PL肌腱（p < 0.05）。使用FDP或PL肌腱作为移植物的SC修复的体积显著小于PW修复（p < 0.05）。FDP肌腱的断裂极限载荷和修复刚度显著高于PL肌腱（p < 0.05）。SC缝线可用作PW的替代品，具有相似的强度和较小的体积，用于使用相似直径的移植肌腱进行修复。在进行屈肌腱移植时，外科医生应了解移植肌腱尺寸和修复方法对强度和体积的影响。
The purpose of this study was to compare two different methods of joining tendons of similar and dissimilar sizes between recipient and donor tendons for flexor tendon grafts. Flexor digitorum profundus (FDP) and peroneus longus (PL) canine tendons were harvested and divided into four groups. The repair technique we compared was a step-cut (SC) suture and a Pulvertaft weave (PW). FDP tendons were significantly larger in diameter than PL tendons (p < 0.05). The volume of the SC repairs using either FDP or PL tendon as a graft was significantly smaller than PW repairs (p < 0.05). The ultimate load to failure and repair stiffness in FDP graft tendons significantly increased compared with the PL graft tendons (p < 0.05). The SC suture can be used as an alternative to the PW, with similar strength and less bulk for repairs using graft tendons of similar diameter. Surgeons should be aware of the effect of graft tendon size and repair method on strength and bulk when performing flexor tendon grafts.
