Knee Cartilage Damage: A Comprehensive Guide
Description
Knee cartilage is a specialized tissue that lines the ends of bones in the knee joint, providing a smooth and cushioned surface for movement. It acts as a shock absorber, distributing weight evenly and protecting the underlying bone from damage.
Cartilage is composed of specialized cells called chondrocytes, which produce a protein matrix of collagen and proteoglycans. This matrix gives cartilage its unique properties of strength, flexibility, and resilience.
Associated Diseases
Damage to knee cartilage can occur due to various factors, leading to a range of conditions:
- Osteoarthritis (OA): A degenerative joint disease characterized by progressive cartilage loss, inflammation, and pain. OA is the most common form of knee cartilage damage, often associated with aging, obesity, and joint injury.
- Rheumatoid arthritis (RA): An autoimmune disease that causes inflammation and damage to joints, including the knees. RA can lead to cartilage erosion, pain, and stiffness.
- Gout: A metabolic disorder that causes uric acid crystals to accumulate in joints, including the knees. Gout attacks can lead to sudden, severe knee pain, swelling, and redness.
- Traumatic knee injuries: Accidents or sports injuries can cause acute cartilage damage, such as tears or fractures. These injuries can result in pain, swelling, and reduced joint mobility.
Did you Know ?
Approximately 1 in 10 adults worldwide suffer from knee cartilage damage. The prevalence increases with age, as OA becomes more common in older individuals.
