A five-month-old male Bernese Mountain dog weighing 27.4 kg was presented for evaluation of an acute non-weightbearing left pelvic limb lameness. Radiographs and CT revealed an avulsion fracture of the femoral attachment of the caudal cruciate ligament (CaCL). A left stifle arthroscopy was performed. Reduction and internal fixation were realised under arthroscopic guidance using a Kirschner wire (1.8 mm) and a single cortical screw (2.0 mm). Ten weeks postoperatively, the implants were removed via arthroscopy. A mild persistent intermittent weightbearing lameness was noted. Normal healing and resolution of lameness followed and the dog was clinically healthy 6 months postoperatively. As in human medicine, surgical treatment of a CaCL avulsion injury in dogs can be performed under arthroscopic guidance. Even though surgical treatment is not always required, it seemed indicated in this case and arthroscopic treatment was successful.
