To evaluate the resistance and regeneration of the patellar ligament after harvesting a graft for reconstruction of the anterior cruciate ligament, using the traditional technique of a single longitudinal skin incision or a technique of two transverse mini-incisions, in sheep.
Ten sheep were used. In the right knee, we removed the graft using the traditional method, and in the left knee, using the two-incision method. The animals were observed for six months. The specimens (patellar ligament, tibia and patella) were adapted to the mechanical test machine for ligament resistance tests.
No difference was found between the two proposed techniques in relation to the regeneration and resistance of the patellar ligament. However, we observed that shortening of the patellar ligament occurred in both groups, and that suturing of the superficial fascia of the patellar ligament did not influence the regeneration of the patellar ligament, according to the histology.
The technique using two incisions in the skin presents the same patterns of regeneration and resistance of the remaining patellar ligament as shown by the traditional technique of a single, longitudinal incision.
在绵羊身上，采用传统的单一纵向皮肤切口技术或两个横向微小切口技术获取移植物用于重建前交叉韧带后，评估髌韧带的阻力和再生情况。
使用10只绵羊。在右膝，采用传统方法获取移植物，在左膝，采用双切口方法。对动物观察6个月。将标本（髌韧带、胫骨和髌骨）适配到机械试验机上进行韧带阻力测试。
在髌韧带的再生和阻力方面，两种提议的技术之间未发现差异。然而，我们观察到两组均出现了髌韧带缩短的情况，并且根据组织学结果，髌韧带浅筋膜的缝合并未影响髌韧带的再生。
与传统的单一纵向切口技术相比，皮肤双切口技术在剩余髌韧带的再生和阻力方面呈现出相同的模式。
