Knee arthritis

Knee arthritis, also known as osteoarthritis of the knee, is a common condition that affects millions of people worldwide. It is a degenerative joint disease that can cause pain, stiffness, and inflammation in the knee joint.

Causes

Knee arthritis can be caused by a number of factors, including:

• Age: As people age, the knee joint can begin to deteriorate, leading to the development of arthritis.
• Genetics: Some people may be more susceptible to developing knee arthritis due to their genetics.
• Injury: Injuries to the knee, such as ligament tears or fractures, can increase the risk of developing arthritis.
• Overuse: Repeated stress on the knee joint, such as from high-impact activities, can lead to the development of arthritis.
• Obesity: Being overweight puts extra stress on the knee joint, which can increase the risk of developing arthritis.

Symptoms

The symptoms of knee arthritis can vary depending on the severity of the condition. Common symptoms include:

1. Pain in the knee joint, especially with movement or weight-bearing activities
2. Stiffness in the knee joint, especially after periods of inactivity
3. Swelling or inflammation in the knee joint
4. Cracking or popping sounds when moving the knee joint
5. Limited range of motion in the knee joint
