Common Triggers and How to Avoid an Injury

The knee is one of the largest joints in the body and bears a lot of weight. That said, it’s no wonder that this joint is susceptible to pain and injury.

Whether you’re an athlete or not, there are several common causes of knee pain. Keep reading to learn a few examples of what causes this condition and how to avoid injuries.


The most common cause of knee pain is arthritis, but there are several types. Osteoarthritis, or “wear and tear” arthritis, occurs when the cartilage between the bones wears down. This can happen due to age, weight, or overuse.

Rheumatoid arthritis is an inflammation of the lining of the joint, which can lead to pain, swelling, and stiffness.

Post-traumatic arthritis can develop after an injury to the knee, such as a fracture or torn ligament.

The best way to prevent arthritis is to maintain a healthy weight, exercise regularly, and avoid injury. If you have arthritis, treatments are available to help relieve the pain and improve mobility.


Bursitis is an inflammation of the bursa, a small sac of fluid that cushions the knee joint. It is caused by overuse, injury, or infection. The symptoms include pain, swelling, and stiffness.


Tendinitis is an inflammation of the tendon, the cord of tissue that attaches muscle to bone. It’s often caused by overuse or injury. Common symptoms include pain, tenderness, and stiffness.

Patellofemoral Pain Syndrome

Patellofemoral pain syndrome (PFPS) is a condition that causes pain around the kneecap. It’s sometimes triggered by overuse, such as running or jumping. The symptoms include pain, tenderness, and popping or grinding sensations.

Iliotibial Band Syndrome

Iliotibial band syndrome (ITBS) is a condition that causes pain on the outside of the knee. It’s often caused by overuse, such as running or cycling. The symptoms include pain, tenderness, and swelling.

Preventing Knee Pain and Injuries

To prevent knee pain and injuries, warm-up before exercising and cool down afterward. Try low-impact movements that avoid repetitive motion.s ake breaks often if you’re doing an activity that puts stress on your knees. If you have bursitis, rest and ice can help reduce the pain and swelling. Physical therapy may also be recommended.
