Osteoarthritis and the various joints involved
Of the several varieties of arthritis, the most common, the most frequently disabling, and often the most painful is osteo- (meaning bone) arthritis, mostly affecting the weight bearing joints (hips and knees) plus the hands, feet and spine. Normally, joints have remarkably little friction and move easily due the lubricated cartilage covering the boney surfaces.
With degeneration of the joint, the cartilage becomes rough and worn out, causing the joint halves to rub against each other, creating inflammation with pain and the formation of bone spurs. The fluid lubricant may become thin and the joint lining swollen to inflamed. Osteoarthritis is also known as degenerative joint disease and affects up to 30 million Americans with both genders in their advanced ages and frequently excelerated by labor professions and traumatic accidents.
