title: Ability of the Tightrope® and percutaneous lateral fabellar suture techniques to control cranial tibial translation.
abstract: OBJECTIVE
  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).
  
  
  METHODS
  In vitro biomechanical study.
  
  
  METHODS
  Cadaveric canine pelvic limbs (n = 18 pairs).
  
  
  METHODS
  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.
  
  
  RESULTS
  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.
  
  
  CONCLUSIONS
  TR and pLFS had similar ability to resist CTT but neither restored the biomechanical properties of an intact CCL.
