abstract: Osteoarthritis is the most prevalent joint disease in the United States. In 1998, the estimated prevalence in this country was 43 million ((1)). Between 1988 and 1994, 18.1% of US men and 23.5% of US women reported that they had experienced significant knee pain ((1)). The prevalence of self-reported arthritis in the United States is projected to increase from 15% of the population in 1990, to 18% (59 million people) in 2000, an increase of 20% ((2)).
