In primary osteoarthritis, the common sites of involvement include the hands, hips, knees and feet 13, 17 ( Figure 1). 1 Biomechanical factors associated with osteoarthritis include obesity, muscle weakness and neurologic dysfunction. 13 – 16 The precise etiology of osteoarthritis is unknown, but biochemical and biomechanical factors are likely to be important in the etiology and pathogenesis. 1 Primary osteoarthritis is the most common form and is usually seen in weight-bearing joints that have undergone abnormal stresses (e.g., from obesity or overuse). The diagnosis of osteoarthritis is based primarily on the history and physical examination, but radiographic findings, including asymmetric joint space narrowing, subchondral sclerosis, osteophyte formation, subluxation and distribution patterns of osteoarthritic changes, can be helpful when the diagnosis is in question.Īlthough osteoarthritis is especially common in older adults, its pathology of asymmetric joint cartilage loss, subchondral sclerosis (increased bone density), marginal osteophytes and subchondral cysts is the same in younger and older adults. Roentgenograms of involved joints may be useful in confirming the diagnosis of osteoarthritis, assessing the severity of the disease, reassuring the patient and excluding other pathologic conditions. More severe symptoms tend to occur in the radiographically more advanced stage of the disease however, considerable discrepancy may exist between symptoms and the radiographic stage. Although the incidence of osteoarthritis increases with age, the condition is not a normal part of the aging process. population ages, the prevalence of osteoarthritis is expected to rise. Osteoarthritis is one of the most prevalent and disabling chronic conditions affecting older adults and a significant public health problem among adults of working age.
