Subchondral bone marrow edema is also commonly seen in patients with degenerative joint disease (10 â 14). Subchondral bone marrow edema in patients with osteoarthritis of the knee joint has been associated with knee pain and the progression of articular cartilage degeneration (12, 13).
Abstract. Although subchondral geodes are a well-known radiological feature of rheumatoid arthritis (RA), large geodes are uncommon. Progressive bone damage with pathological fractures has been reported.he pathophysiology of geodes involves changes in intraarticular pressure ã2ã , cartilage destruction by the pannus, and penetration of fluid and synovial membrane into the subchondral bone 1 and 4. As we will see, other mechanisms may be involved also.
