In individuals older than 55 years, the prevalence of osteoarthritis is higher among women than among men. [59] Women are especially susceptible to osteoarthritis in the DIP joints of the fingers. Women also have osteoarthritis of the knee joints more frequently than men do, with a female-to-male incidence ratio of 1.7:1. Women are also more prone to erosive osteoarthritis, with a female-to-male ratio of about 12:1.
