title: [Radiodiagnosis of the rupture of the meniscus of the knee. Auxiliary maneuver without contrast medium. Preliminary report (author's transl)].
abstract: Some times the diagnosis of injuries of the semilunar cartilages of the knee joint is very difficult and special studies are required like arthrography or arthroscopy needing previous training. The author states a simple manouver to obtain anteroposterior simple X-rays with valgus and varus forced position on the knee joint. Its possible to observe some times intraarticular gas in the knee joint (vacuum image) and this represents a tear of the meniscus as confirmed by surgery.
