Study: Steroid Injections Do Not Relieve Knee Pain
New research published in JAMA shows that people with knee pain caused by osteoarthritis (OA) don’t benefit from corticosteroid injections. According to the recent study, steroid injections administered every three months are no more effective than placebo in relieving painful symptoms of OA of the knee.
The study involved 140 patients with knee pain, reduced mobility, and inflammation of the synovial membrane—which lines the knee joints—caused by osteoarthritis. Seventy of the study participants received a corticosteroid injection every 12 weeks for two years and 70 received a saline solution placebo.
The researchers—from Tufts Medical Center in Boston—discovered no significant difference in symptoms between the two groups and found more adverse effects related to treatment in those who received the steroid injections. They also determined that, over the course of the study, regular corticosteroid injections resulted in an even greater loss of bone cartilage volume and recommend against the use of steroid injections to treat osteoarthritis of the knee.
