That the knee can attain any degree of stability in extension, and indeed is not even more vulnerable, is due to the all-important quadriceps and to the complex action which differentiates the joint from a simple hinge -namely, the screw-home movement. This is the mechanism whereby, at the completion of extension, the tibia rotates laterally by the indirect action of the quadriceps, guided in its course by the anterior cruciate ligament and the form of the articular surfaces. The screw-home movement is an important feature of the knee-joint mechanism not only because it determines the stability of the joint in extension but because disorders of its complex action are responsible for most of the common internal derangements of the knee.  2, record 1, English, - screw%20home%20motion

Biomecánica de los meniscos de la rodilla y su relevancia en la carrera de larga distancia. Cuando se pasa del movimiento de extensión al de flexión, la tibia realiza una rotación interna automática progresiva respecto al fémur y al pasar de flexión a extensión, la tibia hace una rotación externa equivalente, provocando un movimiento de atornillado de la rodilla en extensión.  1, record 1, Spanish, - movimiento%20atornillado%20de%20la%20rodilla

Generally each of these rotations [of the telescope, of the alidade, of the alidade and the lower plate] can be carried out by a slow motion screw (or tangent screw) .... If a large rotation has to be made, then a clamp can be released and the particular component can be rotated freely about its axis. The clamp has to be on before the slow motion screw drive is engaged. The slow motion screws enable accurate setting of the alidade or the telescope to be made.  4, record 2, English, - tangent%20screw

Vis micrométrique qui sert à compléter un déplacement angulaire en faisant une rotation, en sens inverse de la rotation initiale, afin de neutraliser le jeu dans la vis.  3, record 2, French, - vis%20de%20rappel

Record number: 2, Textual support number: 1 CONT

La vis de rappel [...] est un mécanisme qui sert à compléter un déplacement angulaire en faisant une rotation, en sens contraire de la rotation initiale, afin de neutraliser le jeu de la vis. Grâce au pas de la vis de rappel, on peut ainsi obtenir une meilleure maîtrise de l'instrument. Étant une vis micrométrique, elle permet de faire des mises à zéro et des pointés précis.  2, record 2, French, - vis%20de%20rappel
