knorpelknötchen

Knorpelknötchen, a German term, translates to cartilage nodules. These are small, benign growths composed of cartilage tissue. They can occur in various locations within the body, most commonly on the fingers, toes, elbows, and knees. Knorpelknötchen are typically slow-growing and often painless, though they can sometimes cause discomfort or restricted movement if they press on nerves or joints.

The exact cause of knorpelknötchen is not always clear, but they are often associated with conditions like osteoarthritis or other forms of degenerative joint disease. They can also arise spontaneously without any underlying pathology. Histologically, these nodules are characterized by the presence of chondrocytes, the cells that produce cartilage, embedded in a cartilaginous matrix.

Diagnosis usually involves a physical examination and may be confirmed with imaging techniques such as X-rays or MRI. Treatment is generally not required unless the nodules cause significant pain or functional impairment. In such cases, surgical removal may be considered. Knorpelknötchen are distinct from other types of growths, such as bone spurs or tumors, and their benign nature means they do not spread to other parts of the body.
