views updated

osteoarthritis (osteoarthrosis) (osti-oh-arth-ry-tis) n. a degenerative disease of joints resulting from wear of the articular cartilage, which may lead to secondary changes in the underlying bone. The joints are painful and stiff, with restricted movement. The condition may be primary or may result from abnormal load to the joint or damage to the cartilage from inflammation or trauma. Treatment consists of analgesics, reducing the load to the joint (e.g. by weight loss), or surgery (osteotomy, arthrodesis, or arthroplasty).
