I had a total knee replacement done 5 months ago and just recently I've started having a burning feeling on the outside of my knee almost like a pulled muscle feeling.my knee is still tight and I've done 17 weeks of pt.i can't bend my knee 120,I can't climb across my bed and also still need to hold on to something when I sit on the potty.i go back to my Dr in December I'm sure he will have to do a mua malapation how ever you spell it.hes been doing x-rays every time I go and says everything looks good but he needs to do a scan to show tendons,muscles because the tightness is under my knee cap.
