[pseudo- + gout]
Chronic recurrent arthritis that may be clinically similar to gout. The crystals found in synovial fluid are composed of calcium pyrophosphate dihydrate (CPPD), instead of urate (urate crystals accumulate in the synovial fluid in gout). CPPD crystals deposit in fibrocartilage, e.g., the meniscus of the knee, the triangular fibrocartilage of the wrist, and these deposits can be identified on radiographs as chondrocalcinosis. The most commonly involved joint is the knee. Multiple joints are involved in two thirds of patients. This condition is treated by aspiration of the joint, nonsteroidal anti-inflammatory agents, and intra-articular injection of glucocorticoids.
