@ernmar, I would like to begin by welcoming you to Connect and to this frequent issue of (TKR) post-surgery pain and
the discomfort that has not responded to PT and just briefly to steroid injections.

May I suggest that you take a look at the whole subject of fascia, the layer of tissue that surrounds all of your muscles, bones and other organs to protect them. Sometimes when the fascia sticks to itself, it becomes restrictive and quite painful. So then you may want to explore Chronic Myofascial Pain Syndrome or MPS. The physical treatment is called Myofascial Release Therapy or MFR.

For me, I followed instructions and thought I had the perfect situation. It wasn't. I went back to my surgeon who jumped up and said come with me. After images, he just looked at me and said, "I'm sorry Chris, it's the fascia."

He was correct and the MFR journey began for two reasons. I had to be able to feel my feet in order to drive, and I wanted to be able to walk without pain if at all possible. Both of those situations have resolved themselves. Yet, it does seem that I do have flares of fascia restriction......and MFR every week keeps the lid on them.

Here is a link to "Strolling under the Skin" that introduces the structure and purpose of the fascia.
The second link is to the website.

@ernmar, have you expressed your concerns about lack of effectiveness so far to your surgeon? What does your PT tell you? Did you ask to see the images and have them analyzed for you so you had even a basic understanding of the body parts and their current status?

Just let me know how I can help without leading you astray. Heaven forbid! We all are committed to seeing you through this situation. Remember that we cannot recommend or proscribe for you. We can share what we have experienced and facilitate introductions to others with greater expertise. And that is a two-way street, we need to hear from you.

Be safe and protected from inner and outer harm.
Chris
