Prolotherapy uses a dextrose (sugar water) solution, which is injected into the ligament or tendon where it attaches to the bone. Theoretically, this causes a localized inflammation in these weak areas which then increases the blood supply and flow of nutrients and stimulates the tissue to repair itself. The treatment is used for many different types of musculoskeletal pain, including arthritis, back pain, neck pain, fibromyalgia, sports injuries, unresolved whiplash injuries, carpal tunnel syndrome, chronic tendonitis, partially torn tendons, ligaments and cartilage, degenerated or herniated discs, TMJ and sciatica.
Another possible injection therapy is the use of Platelet Rich Plasma (PRP) In PRP therapy, blood fromthe patient is cenrtifuged and concentrated platelets are then injected into the injury site. The PRP has been shown to contain high concentrations of various enzymes and growth factors known to stimulate soft tissue healing and tissue ingrowth. This technology has been around since the 70's, but has become much more popular recently.
Finally, arthroscopic repair of the gluteus medius is now being done by more and more orthopedic surgeons. You are correct in your analogy to the repair of the rotator cuff tendons. One caveat, this is new technology. Be sure your surgeon, if you go this route, is experienced in hip arthroscopy in general, and gluteus repairs specifically.
Thank you so much for your comments. I had not heard of PRP previously. I couldn't agree with you more in not having arthroscopic repair done by someone not specifically experienced in this type of surgery, and especially with repair of the gluteus tendon. I know of a doctor at HSS who has done work in this area, and I hope to be able to speak with him about taking me on as a patient. As you state, to just find someone to go in w/o the experience is not the way to go. I will look into PRP, but I've wasted so many years without resolution I feel the time has come to bite the bullet and try to resolve the problem once and for all. Again, thanks for your response and encouragement.
