Painful TKR: A bone scan is only one element of working up a painful tkr. Expect also x-rays, blood tests, a joint aspiration, a labelled white cell study, and possibly more. When all the data is compiled, then hopefully your surgeon will be able to determine the cause of your pain and correct it. This could include revision tkr.

Osteomyelitis: A bone scan may only reveal metabolic/physiologic changes in the area and not yield a specific diagnosis, but is suggestive of infection, as is loosening of the tkr. If you are only seeing the orthopedist would strongly suggest you request a consult with an infectious diseases expert. This is potentially very serious and will require both to resolve the issue if it is infected. Go soon. Good luck.

The test is abnormal: But nonspecific. All three things look the same on a bone scan. Your doctor will most likely order a tagged white blood cell scan to narrow the diagnosis. Occaisionaly, MRI and even bone marrow scans are needed in addition to plain xrays.
