Robert Moore, MD addresses a viewer’s question about correcting severe ankle deformation caused by long-term steroid use for rheumatoid arthritis. He explains that rheumatoid arthritis, unlike osteoarthritis, involves active inflammation that damages the joint. Early intervention with X-rays, MRI, and possibly arthroscopic examination can help clean up and trim damaged cartilage, slowing disease progression. For advanced cases with severe erosion, surgical options like ankle joint replacements or fusions are available.
