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.[1]
Causes
Knee arthritis can be caused by a number of factors, including:[2]
- 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:[3]
- Pain in the knee joint, especially with movement or weight-bearing activities
- Stiffness in the knee joint, especially after periods of inactivity
- Swelling or inflammation in the knee joint
- Cracking or popping sounds when moving the knee joint
- Limited range of motion in the knee joint
Treatment
The treatment for knee arthritis depends on the severity of the condition. Common treatments include:[4]
- Medications: Over-the-counter pain relievers, such as ibuprofen or acetaminophen, can help to reduce pain and inflammation. In more severe cases, prescription medications may be necessary.
- Physical therapy: Physical therapy can help to strengthen the muscles around the knee joint, which can reduce pain and improve mobility.
- Injections: Corticosteroid injections or hyaluronic acid injections may be used to reduce pain and inflammation in the knee joint.
- Surgery: In more severe cases, surgery may be necessary to repair or replace damaged tissues in the knee joint.
Prevention
There are several steps that can be taken to prevent the development or progression of knee arthritis, including:[5]
- Maintaining a healthy weight to reduce stress on the knee joint
- Wearing appropriate shoes for physical activity
- Avoiding activities that put excessive stress on the knee joint
- Practicing good posture to avoid placing unnecessary stress on the knee joint
- Strengthening the muscles around the knee joint through regular exercise
Conclusion
