Hi there,
This is Dr Basu, experienced Internal Medicine Specialist.
I am here to address your concerns and provide great service.

That means you likely have pseudogout problem.

Calcium hydroxyappatite crystals can deposit around the joint.

This is not usually serious but can cause pain.

The deposits can be removed arthroscopically if needed.

Best wishes,
It was my pleasure to help you today.

I have a different answer.

this situation is classic for myositis ossificans.

It happens in people who have had arthritis for years after hip or knee replacement.

It is ossification of the surrounding tissues after replacement. Bone formation.

It is more common if you had arthritis for a long time.

The above will not let me edit my post.

This condition is more common after hip replacement.

More rare after knee replacement.

However, it is certainly more common that pseudogout. Only one case of pseduogout has been reported after knee replacement.

In fact, psedogout would not arise in a prosthetic joint in general.
