Abstract:
A case of bilateral simultaneous stress fracture of the patella is presented in a 64 year old Marathon runner sustained when he slipped off a curb whilst out walking. This was confirmed on Xray and treated by tension band wiring using the AO technique. He had an excellent result returning to normal function in both knees. This case is unusual since the fractures were not due to osteoporosis, as would be expected in this age group.
