Sorry I missed your comment and yes I have posted that I had very good success with prolotherapy and with PRP. It is all about ligaments that are overstretched and do not do their stability job. I still have hypermobile joints ... the SI Joint was my original joint issues that took 6 doctors to find the prolotherapy answer. When the illiopsoas ligament responded and tightened up again the SI Joint stop causing my leg to sublux! I still must pull the knee to the chest on occasion to reset the SI Joint as it still moves a bit too far sometimes.
I had PRP to remove scar tissue from my groin scar from the hip operation by the doctor who ignored the info I gave him and did not sew up the incision the special way connective tissue disorder requires. PRP did the job will without more surgery.
