Hi Kelly! I know the feeling of one step forward and two steps back, but hang in there. You will make progress. Until I passed the 6 month milestone, I thought I would never get over this. Now, I just have swelling - that makes the knee tight and is uncomfortable. How is your gait? I turn my foot out ever so slightly and that makes my knee have a twinge and it clicks more. If I really pay attention to my walking, and turn that foot inward (actually straight ahead) it feels better. Try to get up and walk every hour. My quad still hurts going the stairs and at times going down, feels like I am ripping the muscles in two. I am still needing to strengthen the quads. Good luck!
