[The value of positive arthrography in the diagnosis and pathogenesis of retrofemoral Baker's cysts (author's transl)].
Retrofemoral Baker's cysts are occasionally found in athletes; they occur as a result of a rupture in the dorsal part of the bursa semimembranosa gastrocnemia. The rupture itself may occur if there is increased pressure in joints or a considerable increase in the amount of synovial fluid. Ruptures can also occur if the joint wall is inadequately adapted and the synovial fluid fails to flow into the ventral joint spaces, as is possible due to certain movements in some sports. Active movement delays healing of the rupture of the capsule: the para-articular structures become encapsulated or, respectively, adhere to one another. Depending on the duration of the effusion and the amount of fluid, the pseudocyst may become pencil-shaped, spherical, cylindrical or rhomboid. It is, therefore, a traumatic pseudocyst, which occurs as a result of insufficient adaptation, principally in athletes of individuals whose occupation involves typical stresses on the knee joint.
