@bah1959 In your description, I don't see anything that talks about physical therapists looking at your pelvis alignment. I know from my experience, when my pelvis moves out of alignment, it effectively makes one leg "longer" and puts a lot of stress on one half of my lower back. It's exhausting to try to walk like this. It also causes sciatic pain and pain that can mimic a lumbar spine problem. This can happen when hip flexors are too tight too because that pulls the pelvis out of alignment. I've struggled with that because I could not bear weight for 3 months after I broke my ankle in May. I sat for 3 months before even trying to walk again and it pulled just trying to stand properly with good posture. It was tight enough that when I tried to walk, I was short strided because my leg wouldn't extend backward. Pelvis alignment also affects knee alignment. I know that when I feel pain on the inside of my knees, that my pelvis is off. My therapist can tell just by looking at me and how I am standing where something is misaligned. If knee misalignment is off, it puts more wear and tear on part of the joint which can lead to damage that could in time create a need for a joint replacement. That's why getting the body moving properly and in correct alignment is so important.

If you are feeling pain trying to bear weight, that pain can be generated anywhere along the path of that nerve from the spine to the leg and there are multiple places where muscles can entrap these nerves.

The other issue is that each surgery you have will create scar tissue and fascial scar tissue that restricts movement. The remedy for that is a physical therapist who does myofascial release, and this can help get a pelvis leveled in the correct position. Developing muscle strength will hold it there. With each of your specialists just looking at their piece of your puzzle, no one is looking at how things might interact on a bigger scale which is where an MFR therapist can help.

Here is a link that explains how pelvis dysfunction can create these issues. You may want to look at that before more procedures. If it helps, you may not need another procedure.
