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.
本研究的目的是比较两种不同的方法，用于在屈肌腱移植中连接受区和供区大小相似及不同的肌腱。采集犬的指深屈肌（FDP）和腓骨长肌（PL）肌腱，并将其分为四组。我们比较的修复技术是阶梯状切割（SC）缝合和普尔弗塔夫编织（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修复的体积明显小于PW修复（p < 0.05）。与PL移植肌腱相比，FDP移植肌腱的极限破坏载荷和修复刚度显著增加（p < 0.05）。对于直径相似的移植肌腱修复，SC缝合可作为PW的替代方法，具有相似的强度且体积更小。在进行屈肌腱移植时，外科医生应注意移植肌腱大小和修复方法对强度和体积的影响。
