We report here, a case of calcium pyrophosphate dihydrate deposition disease, presenting as progressive bilateral knee pain that simulated osteoarthritis. A 52 year old male patient presented with gradually progressing bilateral knee pain of 2 year’s duration. Plain X-ray films showed osteoarthritic changes and osteochondral loose bodies. The nodular crystal deposits with the characteristic features of CPPD crystals in the synovium at histology, aided in arriving at the correct diagnosis.
