Good evening @bresher,
Here is the description from Mayo Clinic for the Iliotibial band syndrome.
"This occurs when the tough band of tissue that extends from the outside of your hip to the outside of your knee (iliotibial band) becomes so tight that it rubs against the outer portion of your thighbone. Distance runners and cyclists are especially susceptible to iliotibial band syndrome."

Actually, I just had an episode of IT band a few weeks ago. My MFR (myofascial release therapist) discovered it when I complained about some discomfort in that area. Using the MFR technique to release the restricted area of fascia interference was her solution and it worked. It took about 30 minutes and I was able to get up and walk out the door without discomfort.

I also think that doing Yoga stretches is helpful to prevent it from happening again. My favorite is "legs up the wall". I make sure everything is working properly by doing some "sit and stands" hopefully without collapsing. Everyone seems to have different muscle tones in that area based upon their commitment to exercising and their past history of athletic endeavors.

How long ago did you have your TKR? Are you working with PT or other advisors during your recovery?

May you be free of suffering and the causes of suffering.
Chris
