2years after tkr, have burning, stiffness after standing in one place for a few minutes, pressure behind knee, actually pressure discomfort in back of leg from thigh to calf. The stiffness after standing for just a short time is what really bothers me. Went through usual therapy and achieved excellent flexibility. Sorry, don t know exact number. Still ride my recumbent bike, walk every day. Within 10 minutes of walking, knee starts to burn. Also am not really steady on my feet anymore because of the difference of leg length. I have neuropathy, but not severe, and wonder if that might cause some of the burning.
Hello, Your symptoms could be related to a pinched nerve. For this reason, I would recommend performing a nerve conduction study to investigate for this possible disorder.  It is also important performing a lumbar column X-Ray study to exclude chronic degeneration of the spine which could lead to irradiating nerve pain in this region.  You should discuss with your doctor on the above tests.  Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
