@njpahl Welcome to Mayo Clinic Connect, a place to give and get support.

It sounds like you have been put through the ringer.

Below I have linked another discussion you might find of interest where members @5rightkneesurgeries @joanna626 @autp17 @clvclv @mal492 @judybearden1 @jenniferhunter have previously discussed IT band syndrome after knee replacement. You may wish to scroll through the previous posts.

May I ask what surgical manipulation would look like and what kind of recovery would be expected?
