&NA; This article reports a major complication of tibial tuberosity advancement with cranial fixation for the treatment of cranial cruciate ligament rupture in a Boxer. Twelve days postoperatively the dog underwent revision surgery for fracture of the tibia and tibial tuberosity. The tibial tuberosity fracture was secured to the tibial diaphysis using the 2 K‐wires and a medial 3.5 dynamic compression plate was used to stabilize the tibial diaphysis fracture. The fracture was reduced and the plate applied using minimally invasive plate osteosynthesis to preserve the blood supply to the bone. Two weeks after revision surgery, the dog was using the operated limb without apparent lameness at a walk and trot. No complications were observed after revision surgery. Tibial tuberosity fracture and tibial diaphysis fracture as complications after tibial tuberosity advancement with cranial fixation healed with satisfactory clinical outcomes but revision surgery was required.
