I have tried water therapy and up to this point has not really helped much if at all. My ROM is excellent. The tight band that I feel starts on the inside of my knee and wraps over my kneecap and goes under my knee. It feels like a wide band or tourniquet. I also have some effusion (fluid) on the lateral side of my knee which the Dr.says will go away as well in time. Praying he is right!
