Poor puppy Tom was playing when this painful injury happened. The x-ray shows the knee – and on the very left hand side, the knee cap. If you look closely, you can see a dark crack which shouldn’t be there, showing the knee cap has been fractured. As Tom is only 15 weeks old and his bones are still growing, the knee cap should repair itself and we’re carefully monitoring his recovery. Hamish found this case particularly interesting as it’s his first patella fracture in 17 years of practice!
