'The Centers for Disease Control and Prevention (CDC) state that nearly one in two people will develop symptomatic knee osteoarthritis by the age of 85 years. While total knee replacement surgery is an option, implants are expected to last only 15 years or so, prompting many sufferers to wait as long as possible before swapping out their own knees for new ones made of metal and plastic.
During the painful years, though exercise and glucosamine supplements may help to some extent, most people turn to over the counter pain relievers for daily relief. These often include Tylenol (acetaminophen) or nonsteroidal anti-inflammatory drugs (NSAIDs) like aspirin and ibuprofen.
These medications come with side effects, however. Already the makers of Tylenol face a number of lawsuits across the nation because of acetaminophen overdose, which is linked with severe liver damage. NSAIDs also come with potential side effects over the long-term, including edema, gastrointestinal upset, and ulcers.
