What is a popliteal cyst?
Poppliteal cyst is the weight of fluid and inflamed tissue that develops behind the knee joint due to acute damage or chronic degenerative disorder. Most cysts are small and painless, but extensive damage to the inner knee components can lead to swelling, tenderness and limited range of movement. Doctors can usually reduce cysts and combat symptoms by the treatment of the basic condition. Aspiration or surgical excision may be necessary if the popliteal cyst is still returning or causing significant pain. Small bags called Bursae, which are present in most body joints, are filled with synovial fluid that pillows and protects the internal structure. If the Bursa behind the knee becomes irritated and inflamed, the synovial fluid escapes into the joint and leads to the development of the cyst. Arthritis is the main cause of the inflammation of the popliteal burs, but the inury from direct wound or poor fall can also lead to the accumulation of fluids.
Most of the popliteal cysts hardly form noticeable lumps in the knee pit, but the untreated mass can potentially grow about 2 inches (about 5 centimeters) in diameter or larger. Large cyst usually feels soft and soft and can turn red or purple. Knee pain is common, although pain is usually associated with basic arthritis or injury than the popliteal cyst itself. The swelling can make the knee bending difficult and carry the weight on the leg. It is important to plan a meeting with a doctor when the knee swelling is significant to receive an accurate diagnosis.
The physician may usually diagnose the popliteal cyst evaluation of the physical appearance of the mass and the scanning of magnetic resonance (MRI). MRI results can detect damage to bones, cartilage, ligaments or blood vessels. Depending on the size of the cyst and the severity of the symptoms, several treatment options can be considered.
Most painless cysts that do not wipe physical activity are not treated. They tend to leave alone in one to six months, andwhich would cause permanent problems. If the cyst causes discomfort, the doctor may decide to aspire it with a specialized needle to relieve tension. If arthritis is determined as the basic cause, anti -inflammatory drugs are usually prescribed to alleviate symptoms. Surgery is rarely needed for a popliteal cyst, but procedure may be required to repair damaged bonds or meniscus tissue.
