Pseudo gout is a condition clinically similar with Gout i.e. sudden and painful swelling in one or more joints.


Pseudo gout is an old terminology. Now a days this condition is popularly known as CPPD (Calcium pyrophosphate deposition arthroplasty).  Main difference between gout and pseudo gout is deposition of calcium pyrophosphate instead of uric acid. And unlike gout no specific treatment is available for CPPD.

 ‌Understanding The ailment

In those aged between 65 to 75 years, it affects 10% to 15% population. Over the age of 85, it affects 60% of population.
