[Diagnosis of ligamentous injuries of the knee joint (author's transl)]

The importance of capsular ligaments, in addition to the collateral ligaments and crucial ligaments, for stability of knee joint is accented. By systematic clinical examination the loss of stability and thereby the injured structures are determined with particular reference to rotatory instability by complex loss of stability. By sketches and tables, the examination procedure for the three topographic fields--medial system, lateral system, and crucial ligaments--is shown.
