This is what they did for me first of all the material of Prosthetic its very hard it give my skin the exzegma, and it wasnt that material of prosthetic they told me to do for me, second nothing is good on the design of my prosthetic, thirdly the knee they give me its not for walking its for running I cant even use it. I went to the 2 differents physical therapy but they cant help me to walk in the knee.
