title: Knee-joint rupture with giant antefemoral cyst formation.
abstract: A case of a patient with Reiter's disease, whose ruptured knee-joint effusion extended proximally along the femur to just below the inguinal ligament, and simulated an iliofemoral thrombosis, is reported. The mechanisms of joint rupture, and the need to differentiate it from thrombophlebitis, are discussed.
