What is loss of articular cartilage in knee joint?

Articular cartilage is a smooth, white tissue that covers the ends of bones in a joint. It provides cushioning and allows bones to move smoothly against each other.

Loss of articular cartilage, also called osteoarthritis, is a common joint condition that occurs when the cartilage wears down or becomes damaged. This can cause pain, stiffness, swelling, and decreased range of motion.

Osteoarthritis is the most common type of arthritis, and it can affect any joint in the body, but it is most common in the knees, hips, spine, and hands.

Risk factors for osteoarthritis include:

* Age (over 50 years old)

* Obesity

* Family history of osteoarthritis

* Joint injury

* Certain occupations (such as kneeling or squatting for long periods of time)

Treatment for osteoarthritis includes:

* Medications to relieve pain and inflammation

* Physical therapy to improve range of motion and flexibility

* Weight loss

* Braces or assistive devices

* Surgery (in severe cases)

Preventing osteoarthritis is not always possible, but there are things you can do to reduce your risk, such as:

* Maintaining a healthy weight

* Exercising regularly

* Eating a healthy diet

* Avoiding joint injuries

* Seeing a doctor promptly if you experience any joint pain or stiffness
