Resumo: Rupture or insufficiency of the cranial cruciate ligament can lead to instability and the development of degenerative joint diseases of the knee. The diagnosis is based on physical examinations, with the execution of drawer movement and tibial compression. Surgical therapy is divided into intracapsular, extracapsular and osteotomy reconstruction techniques. However, no surgical technique is capable of stopping the onset or progression of degenerative joint disease. In this thesis, we sought to validate the modified TightRope technique with number 1 polyester surgical rope and the modified over the top technique with number 1 polyglactin surgical rope for stabilizing the knee of dogs with cranial cruciate ligament rupture. Presented below are two studies that compared tibial compression, drawer movement and caudal displacement of the femur on x-ray at four different times (intact ligament, ruptured, repaired with tibial fabelo suture and repaired with the technique proposed by each article). The first study evaluated the extracapsular TightRope fiber tape technique modified with number 1 polyester surgical rope and study 2 the intracapsular method with number 1 polyglactin surgical rope in the modified over-the-top technique. Eight pelvic limbs (four cadavers) were used for the study. To manufacture the implants, a measurement of two threads per kilogram of body mass was assumed. It was possible to state that both the stabilization with the modified TightRope fiber tape technique with surgical rope and the modified over-the-top technique were successful in stabilizing the knee, as there were no statistical differences in drawer movements and tibial compression when purchased with the already established technique of fabelotibial suture and with the ligament still intact. The techniques proved to be effective in stabilizing the knee of dogs ex vivo, which encourages study and application in patients with long-term follow-up.
