there's still the argument about him not getting cramp or injuries to the lower part of his legs which able bodied athletes have to endure and ask if that is fair.
There's also the amount of energy that is expended just to stay upright on prosthetics. Never mind the forces exerted on the amputated limb where it fits to the prosthetic and how that load bearing is distributed across the stump. I imagine the blades give him an advantage, but when you take into account all that he's at a disadvantage with by not having a physically attached limb and all the musculature and skeletal requirements for the most efficient use....
Now if he had a prosthetic which was bonded/moulded into where the bone was cut giving him back his skeleton and hydraulics and motors to replace the functions of muscles, tendons and joints. That would be a different story.
