RESUMO
The anti-inflammatory and immunosuppressive properties of steroids allow their use in a wide variety of rheumatological diseases, asthma, inflammatory bowel disease, cancer therapy, and severe viral infections. Though life-saving or organ-saving, long-term clinical use leads to a vast array of complications. Osteoporosis is the most common orthopedic side effect of steroid abuse, while osteonecrosis is a rare occurrence. The risk of osteonecrosis appears to be dose and duration dependent, but several patient factors also play a major role and usually affect the femoral head followed by the knee joint. The long-term effects of steroids must be explained to all patients on therapy, but this risk is missed in individuals who abuse steroids for recreational or performance-enhancing purposes. We describe a male, aged 29 years, who presented with dull aching bilateral knee pain of 2-years' duration after a long-term steroid abuse for weight and muscle mass gain. Radiological and magnetic resonance imaging studies confirmed osteonecrosis of femoral and tibial condyles and secondary degenerative arthritis of the knee joint. Prompt suspicion, early diagnosis, and intervention in osteonecrosis of knee joints, and termination of steroids may reverse the pathology and prevent progression of disease.
