Calcium pyrophosphate dihydrate deposition disease (pseudogout) after total knee arthroplasty.

The authors report a case of calcium pyrophosphate dihydrate deposition disease (pseudogout) presenting in the early period after primary total knee arthroplasty. The patient's symptoms resolved with conservative management including colchicine and indomethacin. The presentation of pseudogout resembles septic arthritis and should be included in the differential diagnosis to prevent unnecessary surgery in these patients.
