"We are now seeing these injections can be very harmful to the joints with serious complications such as osteonecrosis, subchondral insufficiency fracture and rapid progressive osteoarthritis," coauthor Ali Guermazi said in a statement. "Intra-articular corticosteroid injection should be seriously discussed for pros and cons. Critical considerations about the complications should be part of the patient consent which is currently not the case right now."
Although the scientists do not fully understand why such issues occur, they believe intra-articular corticosteroid may be toxic to the cartilage. However, more research is needed.
