title: Ruptured bilateral synovial cysts in presumed gonococcal arthritis.
abstract: A man with gonococcal urethritis who developed septic arthritis of both knees is described. The arthritis was complicated by rupture of bilateral synovial cysts. A rise in serum gonococcal complement-fixation antibody titer was demonstrated. Complement-fixing gonococcal antibodies with a high titer were observed in this synovial fluid. The patient responded well to antibiotic treatment and there was no permanent damage to his knee joints.
