I underwent bilateral knee replacement. I had been unable to walk much prior to surgery because of OA and pain. My leg muscles became weak. Since surgery my walking has improved significantly. I have no pain. I have been working on strengthening my leg muscles. However, my proprioception and position sense in my legs are diminished. Nerve conduction studies showed some mild non-specific sensory neuropathy, non-alcoholic and non-diabetic. Subsequence, consequence, or coincidence? Not clear.
