Good evening @krenn. It is great to be able to welcome you to Connect. Our purpose here is to help each other by sharing. And to support that mission, I will now cut to the chase about scar tissue post-TKR. I have had two of those surgeries. After the first one, I developed excessive scar tissue and all my great exercise and strengthening efforts went right out the window.

Imagine how thrilled I was to be introduced to MFR, Myofascial Release Therapy. It took about six weeks to get the restrictive fascia and scar tissue released and then it was over.

And then came TKR #2 and I was ready. My PT, worked closely with my MFR therapist from day one after the surgery. The result.........this time I did not have scar tissue build up. It didn't have a chance with those two ladies being on top of it.

Are you familiar with MFR? Here are two links to get you started. One explains what fascia does and how it can become restrictive. The second one is written by a fellow mentor @jenniferhunter. She and I are both huge supporters of MFR and this is an introduction.

Recommend you look into myofascial release therapy and shock wave therapy, the latter a small jackhammer like tool that sends sound waves in to break down scar tissue. It doesn’t hurt like the MFR but don’t mind the MFR as long as it’s working.
