Tears to the cranial cruciate ligament account for 90% of all canine hind-limb stifle injuries. The most common surgical repair method, lateral suture stabilization, has a 25% failure rate. The purpose of this project was to create an aiming guide to reproducibly locate anatometric points on the canine stifle. Cyclic cadaver testing and tibial translation testing was completed on 9 cadaver stifles. The results of these tests suggested that femoral point f2, and the tibial point t8 are the most anatometric points due to limited strain on the suture during the stifle range of motion and high forces required for tibial translation. A drill guide was created to aid surgeons in locating the points and ensuring a reproducible surgery. Veterinary surgeons validated the device’s function.
