[Osteoarthritis].
BACKGROUND
Osteoarthritis is among the most common causes of functional disability and severe pain, and the prevalence of arthritic symptoms among adults is more than 50%. The article discusses epidemiology, pathology and treatment options.


METHODS
The review is based on a non-systematic search in PubMed and the authors' experience with treating this patient group.


RESULTS
Osteoarthritis is a degenerative disease which leads to loss of joint functioning. Symptoms usually present in the hip, hands and knees. Women are affected more often than men and the prevalence increases with increasing age. Some families have an increased prevalence of osteoarthritis, but the genetic etiology is not clear. Mechanic conditions such as overweight and heavy physical work explain some of the pathogenesis, but non-mechanical factors are probably involved as well. Loss of weight is likely to have a preventive effect, and surgical correction of mechanic conditions such as hip dysplasia and varus deformity can prevent development of osteoarthritis. Treatment of symptomatic osteoarthritis includes educating the patient and continues with stretching, physical exercise, weight reduction, technical aids (supporting braces, walking sticks) and analgesics. Subsequent options are treatment with paracetamol, NSAIDs and possibly opiates and finally insertion of an artificial joint. Many patients with disabling osteoarthritis function much better and have markedly less pain with an artificial joint.


CONCLUSIONS
Current treatment options alleviate but do not cure arthritic symptoms; preventive actions should be instigated when possible. Treatment of osteoarthritis involves many medical specialties and treatment modalities.
