Help Me Get a Prosthetic Leg

HI, I am Smit, a cancer survivor. i was diagnosed with osteosarcoma in 2010 and underwent a TKR ( total knee replacement ) in august 2010. There were complications that arose during the initial surgery, Footdrop ( no movement nor sensation in the ankle ) as well as other problems. I had to undergo 3 major surgeries to save my leg. In 2015, due to an implant related infection , i had to undergo two more major operations. This year, the implant near my ankle was displaced and the Dr had to perform a below knee amputation.  After having gone through so many surgeries, i would be forever grateful if you help me get a good prosthetic foot. Thanks.
