I have lots of dry gangrene on right foot, lost 4 toes , but it doesn't go past the mid-foot. Why would they amputate to knee? Why not just that part?
I have dry gangrene on right foot covering 4 toes and it extends only until mid aspect of foot. But my doctor recommends amputation to knee, can you tell me why can't they amputate only the affected part of foot with gangrene?
