【 摘 要 】

The purpose of this study was to describe and assess the feasibility of a newintra-articular approach in the treatment of cranial cruciate ligament deficiency in dogsusing an artificial ligament and a new bone-anchor system. Twelve canine cadaversweighting 26 to 45 kg were used in this ex-vivo study. Special tibial andfemoral screws, two helicoils, and a high resistance artificial fiber compose the implant.Surgery was performed using the cranio-lateral approach to the stifle joint. Helicoil andtibial screw, connected to the fiber, were inserted in the center of the tibial insertionarea of the cranial cruciate ligament. The fiber was passed over-the-top,tensioned, and fixed to the femoral screw, previously inserted with the helicoil in thedistal part of the femur. Surgery was completed in all the cases. Occasional problemsfound during the insertion of the helicoils and screws were resolved with simpleprocedures. Post-operative clinical assessment showed negative cranial drawer test,negative cranial tibial thrust, and normal range of motion. Radiographic evaluation showedan appropriate positioning of both tibial and femoral implants in all the cases. Theresults of the first surgical appraisal of this new technique are encouraging, althoughfurther studies are necessary to demonstrate the in vivo efficacy of thisprocedure.
