I visited an Orthopedic Dr. and was told that I had slight to moderate arthritis on the inside of my right knee. I have been experiencing difficulty walking due to pain on the right side of my leg, equal to where my knee is.I was told that my IT Band was injured and maybe a tendon. No MRI, x-rays only. I was given 3 options, continue my PT, add a cortisone shot to the treatment and if that wasn t successful, then a total knee replacement. The total knee replacement sounds drastic, I ve not had any knee problems, this was a sudden onset that I have no idea why. Any suggestions on treatment.
