Osteoarthritis: A full evaluation is a must! conservative treatments would include acetaminophen, anti-inflammatories, sometimes pain killers, usually for breakthrough pain and most importantly physical therapy and life style modifications - proper footwear, finding a comfortable bed, assistive devices, knee brace. Supplements such as chondroitin/glucosamine are not effective in advanced disease.
