According to an article published of the journal, Arthritis and Rheumatism, only 44% of knee replacements were indicated! This means that 56% weren't clearly indicated. You have to ask yourself why this is so. Is it because orthopedists do too many operations because they want the business? Is it because MDs are poorly trained and don't know about integrative approaches such as chiropractic, acupuncture, bodywork, infrared light therapy, magnetic therapies, DMSO, nutritional supplements, etc.?
