It must be frustrating to know the scar tissue is there, but beyond reach of traditional therapies. It looks like you have been trying for a long time to deal with the scar tissue - have you consulted with an arthrofibrosis specialist? My Mom also got some relief from acupuncture - it didn't completely get rid of the scar tissue, but seemed to "soften" it.

@sharonbrenna Thanks, Sharon. I wanted to explain a bit about fascia. Think of it as a cob web type net that is 3 dimensional. If I pull on one side of it, that pull extends deep into it and even affects the other side of it. Now imagine that inside this 3 dimensional net are your bones and organs. Your organs are held together by connective tissue and guess what.. fascia. The fascia extends through and around organs. When my PT is stretching fascia with shearing pressure on the surface of my chest, I feel the tingle and pull from that deep into my chest and internally even around my heart and lungs if that is where it was tight. It is like following a map around the body. My PT can feel with her hands where it is tight when she is trying to move it. If there were no problems and everything just moved as it should, she would not feel any tension, but when she does find it, she finds the pathway that connects it to other things. The fascia also conducts electricity and helps in removal of waste products. When it gets stuck, those waste products are stuck too held in the tissue. The picture you see in the video below is fascia.

Does this seems like crazy stuff? It is what happens at a more intimate layer in the body. If you try MFR therapy (myofascial release), would you share your experience of what you think about it?

Here is a video that shows living fascia that starts at about the 11 minute mark so you can actually see how it moves.
