Overview Named after Dr. William Morrant Baker Most common popliteal mass, with a prevalence of 4,5% Synovial fluid collection in the Semimembranous Bursa Found between medial head of the gastrocnemius muscle and the semimembranosus tendon In adults it most commonly arises in association with arthritis or mennisical damage. Found in ~50% of RA patients In children it usually appears without associated knee pathology and can remit spontaneously Ranges in volume from 1-40 ml

Associated Conditions Arthritis Osteoarthritis, RA, Juvenile RA, Gout, Reiter syndrome, Psoriasis, SLE Internal derangement of the knee meniscal tears, anterior cruciate ligament tears, osteochondral fractures Infection (septic arthritis, tuberculosis) Chronic dialysis Hemophilia Hypothyroidism Neuropathic osteoarthropathy (Charcot joint) Sarcoidosis

Symptoms Swelling Pain Knee Effusion Thrombophlebitis Clicking, Buckling or Locking of the knee Leg edema In case of cyst rupture there will be erythema, pain and swelling
7
Diagnosis On inspection there will in most cases be a visible a mass in the popliteal fossa when the patients leg is extended. On palpation the cyst can most easily be felt when the knee is slightly flexed. Diagnosis is made by ultrasound, showing a cyst communicating with the joint space. Might also see calcifications or popliteal artery displacement. Cyst will also show up on X-Ray and MRI Aspiration can be used to determine that the cyst contains synovial fluid

Treatment For asymptomatic or mildly symptomatic cyst, rest and elevation of the leg may be sufficient Drainage and corticosteroid injection into the cyst Surgical resection is reserved for severe cases, with recurrence being a common problem Treat the underlying cause
