Osteoarthritis is perhaps the fastest growing form of arthritis in the United States. According to the Arthritis Foundation, one third of all adult Americans have x-ray evidence of osteoarthritis. Last year over 7 million visits to the doctor were osteoarthritis related which is second to cardiovascular disease in America. As we age this number is going to increase unless we take steps to stop arthritis. Over the years researchers have developed medications to help relieve pain but none have actually addressed the underlying cause of joint destruction. In this article we will take a look at the characteristics of osteoarthritis and the current treatments available. Also, we will look at natural alternatives that can help improve quality of life.

Osteoarthritis is a disorder that involves certain bones and joints in the body. A joint is where two bones are connected and made up of cartilage which is surrounded by muscles and tendons. Some joints have a limited range of motion such as a rib in the rib cage and others have a much wider range of movement like hips, knees, elbows, wrists, and thumbs. The wider ranges of motion joints are called synovial joints. (1) Synovial joints have a unique structure. The bones that are connected to synovial joints are cover in a tough fibrous tissue call cartilage. This tough cartilage tissue between the bones is called the joint capsule. The joint capsule has an inner cavity which is lined with an inner membrane called the synovial membrane. With in this membrane there is fluid called synovial fluid which is a thick, slippery fluid that fills the small places in between and around the two bones connecting. The fluid is filled with a substance that lubricates the joints and eases movement. (1,2)

This joint cartilage serves two purposes. First, it allows for a smooth surface to bear heavy weight and ease joint movement when in motion. Secondly, the joint cartilage absorbs shock and distributes the forces and mechanical stresses out to the bones connected to the joint.

Joint function is under continual mechanical stress while in motion and the joints ability to resist the stress reflects its health. If the mechanical stress becomes to much for the joint, some physical changes occur in the joint cartilage covering the bones. (1,2)

Cartilage is tough and some what elastic in nature comprised of water, collagen and complex proteins called proteoglycans. (3) When osteoarthritis has been diagnosed in a patient, the cartilage has started to weaken and become frayed. Over time the cartilage breaks down exposing the two bones of the joint. When two bones rub together all sorts of damage can happen. Bits of bone and cartilage break off and float around in the joint space. When the joint is bent, one usually experiences a gritty grinding feeling which is painful. Over time tiny bone spurs can grow into the cartilage and surrounding tissue causing a great deal of pain and decrease range of motion in the joint. As the arthritis progresses, the pain and discomfort will increase creating sleepless nights and miserable days.

Even though the exact cause of osteoarthritis is not known, researchers do know that it is not age related. Researchers have observed the disease having the same destructive changes in younger patients diagnosed which haven’t been observed in older individuals who don’t have the disease. (2,4,5) Researchers have observed that certain conditions do seem to trigger the disease or make it worse.

Families who have frequent occurrences of osteoarthritis tend to lean on the idea that it could be a genetic factor. Osteoarthritis of the hands is often seen as genetic. (2) People who are extremely active or have physically demanding jobs have a higher occurrence of developing osteoarthritis. Also, individuals who have certain bone disorders are prone to osteoarthritis as well. Individuals who are over weight are at risk. Because of the excess pounds, these individuals usually develop osteoarthritis in the knees and feet. Over weight individuals usually have denser bones which do not absorb as much shock as thinner bones might causing more damage to joint cartilage.

Currently there is no sure way to prevent osteoarthritis, but slowing the progression may help with some lifestyle changes. The arthritis foundation suggests individuals who are prone to osteoarthritis should maintain a healthy weight and loose weight if needed. They also suggest that these individuals should exercise on a regular basis as a preventative measure. (4) Consumption of Calcium and other vitamins such as vitamin A, C, D, and E can help as well.
