Sorry Steve, I see I replied to the wrong message here...
My cat stepped on a rat trap in a neighbor’s yard. The middle 1/3 of his tibia was displaced. Vet drilled through knee cartilage to place rod, and again to remove later. I treated cat with the Assissi Loop product. He has full range of motion and runs around like a kitten. Vet finds no defect in the knee (X-ray).
