What are symptoms and treatments of Baker’s cyst?

Baker’s cyst is also known as popliteal cyst. It refers to synovial cyst of popliteal fossa or the posterior bulging of the synovial capsule of the knee joint.

Baker’s cyst is formed by the sac effusion between the medial head of gastrocnemius muscle and the semimembranous muscle, and is often connected with the knee joint.

Symptoms of Baker’s cyst are as follows:

  • The patients may feel discomfort or swelling in the popliteal fossa after a walk. Some patients may have no symptoms.
  • When the cyst is large, it can hinder the flexion and extension of the knee joint.
  • It can be found that the popliteal fossa has cystic masses varying in size through examination.

Treatments of Baker’s cyst:

Treatments for children and adults in Baker’s cysts are different.

  • Baker’s cyst in children is often not connected with the joints and is rarely combined with intra-articular lesions. Therefore, it generally can heal on its own.
  • Baker’s cyst in adults is often accompanied by intra-articular lesions. Therefore, it is better to have surgery to remove the cyst and treat intra-articular lesions. Otherwise it is easy for Baker’s cyst to relapse.

In principle, the popliteal cyst should be removed. Patients who are asymptomatic do not need treatment.
