Before assessing your knee pain, it’s important for you to understand what may be happening at your point of pain. Here are some insights into how your knee works and how important cartilage is to being able to function pain-free.
How your knee works
Your knee is a complex joint serving as the meeting point for three major bones: the tibia (shin bone), the femur (thigh bone), and the patella (kneecap). In order for your knee to flex freely, articular cartilage must protect where hard surfaces come into contact.
Healthy cartilage is critical for protecting your knees
Cartilage is a strong, rubbery tissue found in many parts of the body, including joints. There are two types of cartilage found in the knee:
- Meniscus—acts as a cushion between the knees
- Articular cartilage—covers the ends of the bones to ensure smooth movement
When cartilage is damaged, it no longer functions well to provide a smooth, impact-resistant coverage of your bone during activities such as walking, kneeling, running, and jumping.
Cartilage does not heal on its own
Unlike other tissues, cartilage does not naturally regenerate. That’s why cartilage injuries are chronic and frequently get worse as time goes on.
77% of knee pain sufferers say they can no longer participate in at least one activity they previously enjoyed because of knee pain.
How cartilage can be damaged
Chronic or repetitive actions
Exercise, sports, or physical work can cause cartilage to weaken and wear over time.
Acute or traumatic events
Falls and accidents can cause immediate and severe cartilage damage.
