9 Causes of Pain Behind Knee When Bending Leg

1. Popliteal bursitis: This is inflammation of the bursa, a small fluid-filled sac that cushions the tendons and bones at the back of the knee. It is often caused by overuse, such as from running or jumping, or by direct trauma to the knee.
2. Baker’s cyst: This is a fluid-filled sac that forms behind the knee. It is often caused by other conditions, such as arthritis or a torn meniscus.
3. Runner’s knee: This is inflammation of the iliotibial band, a thick band of tissue that runs along the outside of the thigh and knee. It is often caused by overuse, such as from running or cycling.
4. Tendonitis: This is inflammation of a tendon, a cord of tissue that attaches muscle to bone. Tendonitis can affect any of the tendons around the knee, but it is most common in the hamstring tendons at the back of the knee.
5. Meniscus tear: The meniscus is a piece of cartilage that acts as a cushion between the bones of the knee joint. A meniscus tear can be caused by a sudden twist or turn of the knee, or by overuse.
6. Ligament tear: The ligaments are strong bands of tissue that help to stabilize the knee joint. A ligament tear can be caused by a sudden force, such as from a sports injury or a car accident.
7. Arthritis: Arthritis is inflammation of the joints. It can affect any joint in the body, including the knee joint. The most common type of arthritis that affects the knee is osteoarthritis, which is a degenerative condition that occurs as we age.
8. Infection: Infection of the knee joint, also known as septic arthritis, can cause pain, swelling, and redness of the knee. It is a serious condition that requires immediate medical attention.
9. Tumor: A tumor in the knee joint, either benign or malignant, can also cause pain.

treatments and definitions for each type of knee bursitis:

Prepatellar bursitis

Treatment:

• Rest: Avoid activities that aggravate the bursitis, such as kneeling and squatting.
• Ice: Apply ice to the affected area for 20 minutes at a time, several times a day.
• Compression: Wrap the affected area with an elastic bandage or compression sleeve to help reduce swelling.
• Elevation: Elevate the affected leg above the level of the heart when resting.
• Over-the-counter pain relievers: Over-the-counter pain relievers, such as ibuprofen or naproxen, can help to reduce pain and inflammation.
• Corticosteroid injections: Corticosteroid injections can be used to reduce inflammation and pain. However, they should only be used sparingly, as too many injections can weaken the tendons and ligaments around the knee.
• Physical therapy: Physical therapy can help to strengthen the muscles around the knee and improve range of motion.
