To compare the ability of the Tightrope® (TR) cranial cruciate ligament (CCL) technique, percutaneous lateral fabella suture (pLFS) technique, and normal CCL to control cranial tibial translation (CTT).
In vitro biomechanical study.
Cadaveric canine pelvic limbs (n = 18 pairs).
Six small animal surgical residents (1 pair each) and a Diplomate of the American College of Veterinary Surgeons (10 pairs) performed TR and pLFS techniques on paired limbs. Two intact limb pairs served as controls. Limbs were assessed by palpation, radiographs, and dissection before mechanical testing of resistance to CTT. Forces resisted during displacement were compared between groups with a mixed ANOVA and post hoc tests.
With 5 mm of displacement, the pLFS resisted 72 ± 45 N and the TR resisted 66 ± 48 N of load. The intact CCL resisted 400 ± 35 N. The intact CCL resisted displacement significantly more than either surgical technique.
TR and pLFS had similar ability to resist CTT but neither restored the biomechanical properties of an intact CCL.
比较Tightrope®（TR）颅交叉韧带（CCL）技术、经皮外侧腓肠豆缝合（pLFS）技术和正常CCL控制胫骨向前移位（CTT）的能力。
体外生物力学研究。
犬类尸体骨盆四肢（n = 18对）。
六名小动物外科住院医师（每人一对）和一名美国兽医外科医师学会的专科医师（10对）对成对四肢进行TR和pLFS技术操作。两对完整四肢作为对照。在对抵抗CTT的能力进行机械测试之前，通过触诊、X光片和解剖对四肢进行评估。使用混合方差分析和事后检验比较各组在移位过程中抵抗的力。
移位5毫米时，pLFS抵抗72±45牛的负荷，TR抵抗66±48牛的负荷。完整的CCL抵抗400±35牛的负荷。完整的CCL比任何一种手术技术都更能显著抵抗移位。
TR和pLFS抵抗CTT的能力相似，但均未恢复完整CCL的生物力学特性。
