Osteoarthritis of the knee is a condition that affects runners and many professional runners has suffered the ordeal. However, it is not hard to get rid of it as you can do so by exercising. Lunges are one exercise that can help you get rid of the ordeal. However, you should first consult a doctor.
It is true that Osteoarthritis is caused and/or exacerbated by excessive exercise, but these days we have an answer!!!!!! By taking collagen-regenerating supplements, it is possible to get back to a sensible level of running again. Talk to your Pharmacist about Glucosamine/Chondroitin capsules as these will slowly and reliably build up the protective cartilage over your joint surfaces. It is slow because your cartilage and sinews have very poor blood supply, but I am now free from Osteoarthritis and I take my supplements every day without fail.... I am told Deer Velvet is very good for ending arthritic joints as well, but only if you are not competing in professional sports.
