Popliteal Cyst

Also known as a Baker’s cyst, a popliteal cyst is a swelling that occurs in the space behind the knee, producing a pain or tightening in the knee joint. The swelling is brought on by a build-up of lubrication (or synovial fluid) in the popliteal bursa sac. Usually the result of arthritis or a cartilage tear in the knee joint, the pain caused by a popliteal cyst typically worsens if the patient flexes or extends the knee.

A popliteal cyst often gets better on its own and eventually disappears. However, it may continue for months or even years before it goes away. If the pain persists, there are several options to help relieve the symptoms. Anti-inflammatory medication and ice may help the swelling go down, as well as wearing support stockings to provide compression. Sometimes doctors will drain the excess fluid from the knee joint, however Baker’s cysts commonly reform over time. If a cyst is particularly large or painful it can be removed surgically, but may reform if the initial cause isn’t fixed. Stem cell therapy can be used to rapidly regenerate the tissue in the knee joint, in an effort to prevent the cyst from returning.
