X-rays are usually normal in the early phase, although it may indicate the presence of fluid in the joint. A radionuclide bone scan using Gallium may indicate inflammation in the joint lining. An MRI may confirm the presence of fluid in the joint, and inflammation of the joint lining as well. Aspiration of the joint is helpful, especially if pus is obtained. Culture could be undertaken to identify the organism involved.
Treatment consists of drainage of the joint.
