Summary
A Baker’s cyst is a relatively common cyst in the popliteal fossa, which is caused by an inflammation and the associated increased production of synovial fluid. Depending on the size of the cyst, it can be asymptomatic or cause severe pain, swelling and restricted mobility. A puncture is a symptomatic treatment that removes pain and pressure from the joint, but does not treat the actual cause.
A causal therapy is indicated. There are a variety of causes for Baker’s cyst. Often NSAIDs are used.
Physiotherapy can also prevent the (re)development of a Baker’s cyst. In case of resistance to therapy or corresponding cause, an operation in which the focus of inflammation is removed can be helpful.
