Trochlear groove replacement in a dog following traumatic loss of the femoral trochlear

ABSTRACT A 2‐year‐old, 19 kg female spayed Pharaoh Hound was presented after a road traffic accident, suffering extensive wounds to both pelvic limbs, including a shearing injury to the left stifle with complete loss of the femoral trochlear groove. Initial management included surgical debridement and lavage of the stifle, with primary closure of the joint and empirical administration of broad‐spectrum antibiotics. The remaining wounds were closed primarily or debrided and healed by second‐intention healing. The trochlear groove was replaced once two successive negative joint fluid cultures were obtained at 4‐week intervals. A size 7 Kyon patella groove replacement prosthesis was successfully secured to a partially osteotomised bone bed, bolstered by an impacted autologous bone graft, filling the femoral bone defect. The dog recovered uneventfully and returned to regular activity, with no reported postoperative complications during the 395‐day follow‐up.
