  • Poplitealna cista = Popliteal cysts
    Mavčič, Blaž
    The popliteal cyst (Baker's cyst, gastrocnemio-semimembranosus bursa) is the most common etiology of a soft-tissue mass in the popliteal fossa. The cyst islined with a synovial membrane and linked to ... the knee joint through a small slit-like opening at the posteromedial joint capsule in the joint space level.The popliteal cyst may serve as a protective mechanism for the knee fromthe chronic joint effusion. The frequency of popliteal cysts is statistically associated with joint effusion, inflammatory arthritis, rupturedmeniscus and the degenerative joint disease of the knee. The poplitealcyst is clinically visible as an elastic intumescence. It can diminish in size after a longer rest and increase again upon walkingžstanding.The diferential diagnosis includes deep venous thrombosis, popliteal artery aneurism, cystic degeneration of arterial adventitia, seroma,haemathoma, abscess and soft-tissue tumors. The diagnosis can be confirmed by an ultrasound, a color-doppler ultrasound or by magnetic resonance imaging. Most patients with a popliteal cyst require conservative measures to diminish the joint effusion. Reduction of the cyst size can be achieved by arthroscopic repair of the primary intraarticular cause of the chronic knee joint effusion or by direct dilatation of the communication slit between the cyst and the joint. Indications for the open surgical cyst removalare rare and can be considered in cases with associated complications. All operative techniques for popliteal cyst removal or size reduction have very high recidivant rates.
