Osteoarthritis (OA) is the most common form of arthritis that occurs when the protective cartilage which cushions the joints wears down. As the cartilage wears away, bones rub against one another, resulting in discomfort and stiffness. OA can also cause damage to the ligaments, menisci, and muscles. It’s estimated that millions of people worldwide experience the condition.
There are two types of OA: primary and secondary. Primary OA is linked to aging and is attributed to the natural “wear and tear” the body experiences over time. Secondary OA, on the other hand, can develop earlier in life and may appear 10 or more years after an injury or other specific cause.
Joint pain in the hands, neck, hips, and knees are some of the most common symptoms, but other joints can be affected as well. The pain and stiffness associated with the condition can make daily activities challenging. OA is progressive, and as such, joint cartilage becomes diseased, damaged, and ultimately, completely worn away over time. Without the coverage between joints, adjoining bones rub together and can cause severe pain, swelling, and stiffness.
