"You might want to investigate laser therapy"
Another emerging therapy for ligament/tendon injuries is Platelet Rich Plasma Therapy. It is used for soft tissue which is poorly suppplied with blood vessels and thus slow to heal. The procedure is as follows: 1) Draw ~30 ml of the patient's blood; 2) Centrifuge it to concentrate the platelet rich plasma component to ~ 900% of normal concentration; 3) Inject the plasma into the injury site guided by ultrasound; 4) Patient stays inactive for 2 weeks and then slowly returns to normal activity as their condition permits. The hypothesis is that, in the presence of injured tissue, the platelets release growth factors that speed healing. Delivering a concentrated dose of them by injection makes up for the lack of blood supply in tendons and ligaments. The procedure is still in the early stages of acceptance and is not covered by most insurance. However, if you can afford $800 it may be worth considering if standard treatments have failed. That was my situation in 2010. After 9 months of trying everything short of surgery to cure quadriceps tendinitis, which had become chronic(tendinosis), I underwent the procedure. The shot is not exactly fun, but neither is it unbearable. Over the course of the next 5 months, I slowly mended and returned to training in the mountains, and was able to go in over Shepherd Pass in the southern Sierra for a 6 day trip in September, 2010. At the time of the trip, my tendon was at about 80% of normal capability, and has continued to improve since, to the point where it now almost back to 100%. I tend to believe it was due to the PRP therapy, although final proof of the therapy's effectiveness is not yet established. A number of rigorous studies are in progress that should resolve the issue in the next year or two. Meantime, if all else fails, what do you have to lose? Besides $800. ;-)
