M11: Other crystal arthropathies

M11.9: Crystal arthropathy, unspecified

Crystal arthropathy, unspecified, is a condition characterized by the accumulation of microscopic crystals in the joints. This buildup can cause pain, stiffness, and inflammation, similarly to what patients with arthritis experience. The type of crystal involved is not identified in this unspecified form of crystal arthropathy. The crystals can initiate an immune response, leading the body to attack the crystals and causing harmful inflammation and potential damage to the joints. The severity and progression of the condition can vary person to person, but it typically affects the knees, wrists, and ankles. During flare-ups, patients may experience intense pain and joint swelling. With time and without management, it may lead to chronic and potentially disabling joint damage.
