Are there any other types of crystal – apart from urate – that can cause joint disease?
The only other common kind of ‘crystal arthritis’ is caused by a certain type of calcium crystal, which is deposited in the joints in a similar way to urate. It may cause acute attacks rather like gout, but this tends to affect the knee more often than the big toe. (See arc booklet ‘Pseudogout and Calcium Crystal Diseases’.
