Synovial ankle cyst: what is it?

A synovial ankle cyst is materialized by a small ball of a few millimeters to a few centimeters in diameter containing a liquid, rolling under your fingers when touched.

It contains a synovial fluid, a viscous liquid that acts as a lubricant in joints and tendons. Its elasticity allows good functioning as well as the good condition of the articular cartilages present in the body. Located in the knee, shoulder, wrist or foot and ankle, it is enclosed in joint capsules.

When the capsule is weakened, the synovial or synovial fluid can deform it and accumulate to form a cystic mass. There are also mucoid cysts of the ankle which are of different histological nature: the diagnosis is based on anatomopathological analysis.

Synovial ankle cyst: causes and risk factors

Do you notice a synovial cyst in your ankle? The causes of this lesion are idiopathic or post-traumatic.

In most cases, this appearance is idiopathic, that is to say its origin is unknown. Nevertheless, it can happen when the joint capsules are altered as a result of a trauma to the ankle such as a fracture or ligament rupture near a joint. Thus, the affected synovial fluid is released and creates a cystic mass observable at the foot.

In addition, some people are more likely to develop cysts such as individuals suffering from osteoarthritis, rheumatism or those subjected to repetitive orthopedic trauma such as high-performance athletes.
