1. An orthosis of the knee joint for guiding the patient’s kneecap when moving from a straightened to bent position of the knee joint and vice versa, comprising a mounting device (1) for attaching to the thigh and lower leg, at least one laterally positioned knee-flexing stabilizing element for fitting to the thigh and lower leg and held in position by a system of tension tapes, a shape-stable guide element (6), which is designed to fit laterally to the patella the base part (7), from which the medially directed extensions (8) extend proximal and distal from the patella and are fixed with tape sections (10, 12) on the orthosis in the thigh and lower leg region so that the medial traction acts on extensions (8) characterized in that the tape sections (10, 12) are made elastic, and with the base part (7) is connected laterally, allowing lateral shift of the base part (7) elastic tape (19), the elasticity of which is greater than the elasticity of the tape sections (10, 12 ), and the elasticity is medially n of the extending tape sections (10, 12), on the one hand, and of the laterally extending tape (19), on the other hand, is selected so that when the joint is bent from a straightened position, the laterally extending tape is at least completely dominantly stretched (19) ), moreover, a tensile limiter (23) is provided for the laterally extending tape (19), which acts at a given limiting angle of flexion of the knee joint, so that for more flexion of the knee joint the media are stretched in at least a predominant way1. Ортез коленного сустава для направления коленной чашечки пациента при переходе из распрямленного в согнутое положение коленного сустава и наоборот, содержащий крепежное устройство (1) для крепления на бедре и голени, по меньшей мере, один латерально расположенный воспринимающий сгибание коленного сустава стабилизирующий элемент для прилегания к бедру и голени и удерживаемый в положении с помощью системы натяжных лент, стабильный по форме направляющий э
