What does intrasubstance degeneration mean?

Intrasubstance degeneration refers to the pathological changes occurring within the substance of a tissue, commonly seen in cartilage, tendons, or ligaments. This condition typically involves the breakdown of the extracellular matrix and cellular components, leading to loss of structural integrity and function. It is often associated with age-related wear and tear or repetitive stress injuries. Intrasubstance degeneration can result in pain, reduced mobility, and increased risk of further injury.
