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).
The surgery is performed by arthroscopy, after the joint is cleaned of calcified cartilage. Through use of an awl, the surgeon creates tiny fractures in the subchondral bone plate. Blood and bone marrow (which contains stem cells) seep out of the fractures, creating a blood clot that releases cartilage-building cells.
