What is Osteorithritis?
Osteoarthritis, a consequence of aging, is a chronic disease of the joints leading to spurring
of bone, pain and decreased mobility and function. Osteoarthritis is also called degenerative
joint disease.
Osteoarthritis is related to a breakdown of cartilage in joints; it commonly occurs in the hips,
knees and spine. Its main symptoms are pain and morning stiffness, which usually worsens
with exercise.
What is cartilage?
Cartilage is a firm, rubbery layer on the ends of bones in healthy joins. It reduces friction in
the joints and absorb "shock".
Cartilage contains a lot of water. When pressure is applied (e.g. standing or walking), some
water from cartilage enters the joint and coats coats the cartilage. When the pressure is
removed (e.g. sitting), the water reabsorbed and the cartilage regains its normal shape. In
osteoarthritis, the cartilage may wear away in some areas causing bones rubbing against
each other in a joint.
To function as a shock absorber, cartilage is made up of four substances" collagen,
proteoglycans, water and chondrocytes. Collagen is a macromolecule to provide a framework
to house other components inside the cartilage. Proteoglycans contains protein and sugar.
Proteoglycans are hydrophilic and they trap water in cartilage. Chondrocytes are the cells
producing new collagen and proteglycans in cartilage. These cells also release enzymes to
break down old collagen and protesoglycans.
Precautions for people with osteoarthritis?
People with osteoarthritis are always advised to start a gentle program of exercise to improve
joint function and avoid any vigorous activities such as soccer and basketball. It may
also be helpful if they take glucosamine alone, or a combined with chondroitin daily for pain
and to protect joints. If needed, patients are always suggested to have weight loss.
Medicines for Osteoarthritis
The common prescribed medicines used for osteoarthritis are diclofenac (Voltaren) etodolac
(Lodine), ibuprofen (Motrin, Advil), indomethacin (Indocin), valdecoxib (Bextra) and celecoxib
(Celebrex). OTC Products include acetaminopen (Tylenol), aspirin (Bayer, Ecotrin, Bufferin),
ibuprofen (Motrin, Advil) and naproxen (Aleve).
Herbs and Supplements for Osteoarthritis
The most commonly used supplements include boswellia [1], cat's claw [2], cayenne [3,4],
chondroitin sulfate [5], ginger [6], glucosamine sulfate [7], SAMe [8, 9] and niacinamide
(vitamin B3) [10-12]. Supplements that may be helpful include cartilage [13, 14],
methylsulfonylmethane [15], cetyl myristoleate [16], collagen [17], devil's claw [18], stinging
nettle [19] and guggul [20],
