Calcium pyrophosphate dihydrate deposition disease (CPPD) is a build up of calcium crystals in the joints. These crystals cause inflammation in the joints, which causes arthritis like conditions known as:
Over time the inflammation can cause damage to the tissue inside the joint and lead to pain and chronic disability. CPPD can be managed with medical care.

It is not known what causes these calcium pyrophosates to form, but genetics appears to play a role.
Increasing age is the most common factor that may increase your chance of getting CPPD. Other factors include:
In most cases, CPPD does not lead to symptoms. Symptoms may come and go in acute attacks called flare-ups.
Pseudoosteoarthritis symptoms are the most common type, especially in the knee. Symptoms may be on both sides of the body, but are generally worse on one side. Pseudoosteoarthritis may cause:
Pseudogout symptoms occur more frequently in the knee, but can occur in other joints as well. There may be periods of time when there are no symptoms. Attacks of pseudogout may be spontaneous, or may be brought on by surgery, or illness. Pseudogout may cause:
Pseudorheumatoid arthritis symptoms occur least frequently and affect both sides of the body. Pseudorheumatoid arthritis may cause:
Your doctor will ask about your symptoms and medical history. A physical exam will be done. Tests can be used to diagnose CPPD, or to rule out other conditions.
Tests may include:
There is no cure for CPPD and nothing is available to dissolve the crystal deposits that already exist.
Treatment of CPPD is focused on managing the discomfort during flare-ups. Without treatment, the pain and discomfort of CPPD will go away on its own within days to weeks.
Talk with your doctor about the best treatment plan for you. Rest, ice, and elevation may help relieve some pain. Other treatment options may include:
Medication may help to decrease inflammation, pain, and stiffness. Medications may include:
Additional procedures may be needed if home care and medications are not effective. Additional procedures may include:
