Chondrocalcinosis is a rheumatologic condition that is characterized by accumulation of calcium pyrophosphate dihydrate crystals or CPPD crystals in connective tissues or the joint cartilages.lthough the exact cause of the disorder is not known, evidence suggests that it might have a hereditary association. Chondrocalcinosis often runs in families and so a genetic link can be suspected. Calcium pyrophosphate crystals accumulate in the joint, firstly in the cartilage and then in the synovial fluid.
