Baker’s Cyst: Symptoms, Treatment, and Prevention
A synovial cyst of the popliteal space, also known as a Baker’s cyst, is a fluid-filled sac that forms behind the knee joint. This condition occurs when synovial fluid, which normally lubricates the joint, accumulates and bulges out from the joint capsule. Baker’s cysts are typically caused by underlying knee problems, such as arthritis, meniscal tears, or inflammation.
The symptoms of a Baker’s cyst can include pain, swelling, and stiffness in the back of the knee. The cyst may feel like a soft lump or a balloon-like swelling. In some cases, the cyst may rupture, causing sudden and intense pain in the calf area.
Treatment options for a Baker’s cyst include conservative measures like rest, ice, compression, and elevation, as well as medications to reduce inflammation and pain. Physical therapy and aspiration, a procedure to drain the cyst, may also be recommended. In severe cases, surgical removal of the cyst may be necessary. It is important to address the underlying knee condition to prevent recurrence of the cyst.
