Femoral anterior glide syndrome, anyone have this?

Hi, all.  I have been posting about my running issues that I have had over my 4 years of running.  The more research I do and the more specialists I see the closer I get to figuring out my problems.  Originally I thought I had pirformis issues and ITBS possibly conrtributing to repeated hip flexor strains.  Just figured out with my current PT the front of the hip pain I get is actually impingement within the hip joint not hip flexor strain.  My last PT diagnosed the anterior glide syndrome over a year ago but his treatment didn't help.  There is more info available on the internet now than there was a year ago about this syndrome.  I really think this is my problem and is worsened by doing hip flexor stretches.  My current PT didn't know what this was so I printed off some info for her.  Will see what she thinks next time I see her.  Anyway, I am starting the exercises at home that I found for this.  They involve improving glute strength/ activation. 

Anyone else have this and been able to correct it?  This syndrome causes the femoral head to move too far forward in the hip joint causing pinching and pain.
