Destructive arthropathy in generalized osteoarthritis with articular chondrocalcinosis

A destructive arthropathy is much more common when generalized osteoarthritis (GOA) and articular chondrocalcinosis (ACC) coexist than in GOA alone. Fifty-two patients with GOA and ACC were compared to a matched control group with GOA alone. A marked increase in the frequency of a destructive arthropathy was found in the group with both GOA and ACC. Nonweight-bearing joints were often involved in the group with GOA and ACC, whereas they were seldom involved in the group with GOA alone.
