Study Notes
- Articular cartilage damage can be caused by injury, excess loading, aging, or joint instability, leading to increased metabolic activity of chondrocytes and synthesis of matrix constituents.
- The reparative response to cartilage damage does not restore it to normal but initiates a process that can lead to further cartilage loss.
- Prevalence and severity of cartilage damage increase with age, with potential risk factors including obesity, joint trauma, and heredity.
- Common symptoms of cartilage damage include localized deep aching pain in affected joints, which worsens with joint activity and improves with rest.
- The distal interphalangeal (DIP) and proximal interphalangeal (PIP) joints of the hands are often most affected by cartilage damage.
