I am currently 4 weeks post op and have been dealing with IT Band issues since before my surgery. Let me fill you in on my situation and you can decide if there are any parallels to yours.
I had to have my hip replaced due to avascular necrosis. As my hip became more and more unstable, my body altered my gait to enable me to walk. I ended up with such an incredibly tight piriformis and IT band that I was stretching them twice a day just to be able to walk around the house. Of course, when I came out of surgery, I still had an injured IT band and piriformis to deal with. My physical therapist has given me new stretches to work on this (I can’t do the do the old stretches due to my movement restrictions), and I do them 3X/day. It’s still a work in progress, but it has helped a lot.
Also, my knee is still sore and bruised. My PT thinks that they had a clamp on my knee and that is where the bruising came from. And of course, being on blood thinners doesn’t help the healing process.
I’m not a medical professional, so take what you like and leave the rest.
