The reported prevalence of osteoarthritis varies according to the method used to evaluate it. In most epidemiological studies it is commonly assessed by radiography. Marked osteoarthritic damage must be present, however, to detect characteristic changes with plain radiographs, and they are therefore not sensitive diagnostic tests. About 6% of adults age 3 30 have frequent knee pain and radiographic osteoarthritis.
The available data about the incidence and prevalence of osteoarthritis are different. For example, OA mostly assessed by radiography which there should be a marked damage to be detectable in radiography.


Osteoarthritis is caused by aberrant local mechanical factors acting within the context of systemic susceptibility. Systemic factors that increase the vulnerability of the joint to osteoarthritis include increasing age, female sex, and possibly nutritional deficiencies. While epidemiological studies have shown a major genetic component to risk that is probably polygenic, the genes responsible have not yet been identified.3 In people at risk, local mechanical factors such as misalignment, muscle weakness, or alterations in the structural integrity of the joint environment (such as meniscal damage) facilitate the progression of the disease. Loading can also be affected by obesity and joint injury, both of which can increase the likelihood of developing osteoarthritis or experiencing its progression.
Near 6% of adults with the age of 30 years suffer from repeated knee pain and in their radiographic evaluation reveal osteoarthritis. As previously mentioned in [[Osteoarthritis risk factors|risk factors]] for [[Osteoarthritis|OA]] are: age, female sex, and nutritional deficiencies, occupational involvements, trauma, genetic, and race.

Overview

Epidemiology and Demographics

The available data about the incidence and prevalence of osteoarthritis are different. For example, OA mostly assessed by radiography which there should be a marked damage to be detectable in radiography.

Near 6% of adults with the age of 30 years suffer from repeated knee pain and in their radiographic evaluation reveal osteoarthritis. As previously mentioned in risk factors for OA are: age, female sex, and nutritional deficiencies, occupational involvements, trauma, genetic, and race.
