Thank you for your comments...I am a little over a year out and my leg hurts so much. The knee is stable, great ROM and I can straighten it and it feel best straight. However, I have hip and lower back pain and pain not on the side of the knee. Maybe more like stiffness and extreme soreness. I've been in PT twice and both times a month or so after being dismissed I"m back to where I was before. I do walk lots, exercise, ride a recumbent bike and do stretching. It seems t more I do the more sore I am, but I'm just as or if I do nothing. Seems like I just can't strengthen the muscles. Ortho is finished with me as everything seems to in place and good with the joint replacement. I won't give up either and I'm 62. Very active as well.
