I was scheduled for knee surgery three times, but it never happened, dut to heart problems and loss of a knee physician. We were advised by a Togus doctor to get a knee brace due to excessive time at the V.A. One V.A. doctor in Caribou advised us to go to Northern Prosthetics in Presque Isle. We have been very pleased with their performance. The staff has been great. Try them, you will be pleased!
