This was a relatively small study group, but it certainly presents information that patients need to be aware of when considering cortisone injections. The study results indicate there may be some people who are more prone to negative results from such injections that can include:
* Accelerated osteoarthritis progression
* Subchondral insufficiency fracture
* Complications of osteonecrosis
* Rapid joint destruction, including bone loss
This study and it's results do not mean you shouldn't consider cortisone injections as a treatment for joint pain when you would prefer to wait for a joint replacement. It just means there are some additional risks (not inevitable events) not been previously identified that need to be discussed with your doctor as you decide what options to take for treatment.
