INJURIES OF THE INTERNAL SEMILUNAR CARTILAGE: POSSIBLE PREDISPOSITION TOWARD; SYMPTOMS AND TREATMENT

The internal semilunar cartilage, like so many other medical subjects, has amassed a large amount of literature. Some is necessary repetition, but this implies no reason for a further rehash of old facts. This paper is written with apologies for the old and accepted matter which it contains; but such reiteration seems necessary for clarity and emphasis. Here we wish (1) to postulate a possible predisposition toward injuries of the cartilage in certain body types, (2) to state a seeming rationale for the treatment of such injuries and (3) to present a statistical summary to dispel prevalent beliefs as to the more common symptoms of injury to the cartilage. The meniscuses are developed from exactly the same primitive mesenchyme as are the femur and the tibia. In the 40 mm. embryo the knee joint is divided into four compartments by a solid mass of mesenchyme extending across the joint. This
