Thank you for your response. It is not metal-on-metal. Surgeon said temp stitches dissolve prior to the muscles being fully healed so he uses permanent stitches. He did not say why those fell apart. He has only ever seen that once before. He cut a slit in the IT band to loosen it.
I wondered if I should contact him again or someone else. He said the x-ray looked fine but don't know why he didn't do an MRI or CT. How do I know if he specializes in revisions or complex cases as you mentioned?

I'm so frustrated. Everyone says how wonderful their hip replacement was. I am healthy, active (or was), of normal-to-under weight and 70 yr. old. No physical or health issues of any kind. I struggle to accept the fact that I can no longer walk more than a few minutes. With the use of a cane to take some of the weight off my leg, I can walk an additional minute or two, so it does help a little. I walk very slowly with small steps (even though I have long legs).
