M19: Other arthrosis

M19.0: Primary arthrosis of other joints

Primary arthrosis of other joints, also known as osteoarthritis, is a degenerative joint disease that gradually worsens over time. Although it typically involves the breakdown and loss of cartilage in one or more joints, in this context, it specifically refers to joints other than those normally associated with osteoarthritis such as the knees, hips, and small joints of the hands. This can include less common locations like the shoulder, elbow, ankle or jaw. Symptoms of primary arthrosis can range from mild to severe and may include stiffness, especially first thing in the morning or after resting, and pain during or after movement of the affected joint. Other symptoms can include loss of flexibility, tenderness when light pressure is applied to the joint, and a grating sensation or noises when the joint is used. This condition is often a result of aging, but factors like joint injuries, obesity, and genetic factors can make a person more likely to develop it.
