Embodiment Construction

[0023] figure 1 and 2 A knee orthosis for a patient's right knee is shown schematically. The orthosis has a sleeve 1 made of braided elastic material to be fitted over the knee joint and adapted to the shape of the knee joint. The sleeve forms the upper leg section 2 and the lower leg section 3 . On its front side, the sleeve 1 has an opening 4 through which the patient's patella protrudes when the orthosis is correctly worn. The sleeve 1 is composed of a plurality of material sections connected to one another by seams 5 .

[0024] Beside the opening, a shape-stable guide element 6 rests against the sleeve 1 and consists of a base part 7 lying beside the opening 4 and a continuation 8 extending therefrom in the middle. , the continuation extends above and below the opening 4 such that the guide element 6 is substantially C-shaped. A corresponding C-shaped edge 9 can be bent upwards from the base part 7 and is optionally cushioned to allow a soft rest on the patella edge. ...

Abstract

The invention relates to a knee-joint orthosis which comprises a fastening means (1),and at least one stable guide element (6) that is arranged to bear laterally on the patella by way of a lateral base part (7) from which medially directed attachments (8) extend proximally and distally of the patella and are secured to strap sections (10, 12) on the orthosis in the area of the thigh and of the lower leg in such a way that a medial tensile force is exerted on the attachments (8). By virtue of the fact that the strap sections (10, 12) are designed with an elasticity, that an elastic strap (19) is connected to the base part, and that the elasticity of which strap (19) is greater than the elasticity of the strap sections (10, 12), the elasticities of the strap sections and of the strap (19) are chosen such that, during a flexion of the joint (14) from the extended position, the laterally directed strap (19) first stretches at least quite predominantly, and a stretch limiter (23), providedfor the laterally directed strap (19), is active at a predefined flexion limit angle of the knee joint, and such that, for a greater flexion of the knee joint (14), the medially directed strap sections stretch at least predominantly.

Description

technical field [0001] The invention relates to a knee orthosis for guiding a patient's patella in the transition from a stretched position of the knee joint into a flexed position and vice versa, the knee orthosis having: for fixation on the thigh and lower leg Fixing device on the upper; at least one stabilizing element arranged on the outside to receive the flexion of the knee joint for resting on the thigh and lower leg; a shape-stable guide that can be held in position by clamping the wall device Element, the guide element is provided for laterally resting on the patella by means of a lateral base part, from which the continuation part directed medially extends at the proximal end and the distal end of the patella And the orthosis is fastened with strap sections in the region of the upper leg and lower leg in such a way that tension is exerted on the continuation. Background technique [0002] Such knee orthoses for guiding the patella (kneecap) are required when the g...
