Embodiment Construction

[0038] Figure 11 is a non-limiting example of a frame for a knee orthosis. For example, the frame has two symmetrical arms ( 1 ) and ( 2 ) articulated approximately at the height of the center of rotation of the knee ( 3 ). In fact, the two arms (1) and (2) are arranged in a known manner on either side of the calf and thigh, and are temporarily connected by any known and suitable means, such as with The fabric covering (E) for the devices of (1) and (2), such as hook and loop straps, remains in place.

[0039] According to an essential characteristic of the invention, as described below, the frame - however it is produced - has previously positioned and oriented restraints in the form of straps (4), (5), (6) and (7) so as to Around the calf and thigh, leaving the patella area unconstrained, the bands cross and overlap each other posteriorly against the skin of the kyphosis at the center of rotation of the knee. These straps serve to prevent the front and upper portion of t...

Abstract

The invention relates to an orthosis comprising an articulated structure (1) - (2) arranged in such a way as to be fixed to the thigh and to the leg, on either side of the knee. According to the invention, the orthosis comprises restraining means in the form of straps (4), (5), (6) and (7) coupled to said structure and able to surround the thigh and the leg, leaving the patellar area free, and to be crossed and placed one over the other on the rear side facing the cutaneous surface of the popliteal fossa (D), at the same height as the centre of rotation of the knee, in order to prevent the front part of the tibia from sliding forwards, each strap (4), (5), (6) and (7) being held in a rigid guide (9) on the leg and the thigh, and being held together by a non-extendible sleeve where they cross over at the popliteal fossa (D). The first strap (4), that is the shortest, is arranged on the outside, as far back as possible, and the last strap, that is the longest, is arranged on the inside, as far forward as possible, facing the cutaneous surface of the popliteal fossa.

Description

technical field [0001] The invention relates to the technical field of orthoses, in particular orthoses for the knee. [0002] The invention is particularly advantageously used in traumatic injuries of the anterior cruciate ligament. Background technique [0003] As is well known to those skilled in the art, the anterior cruciate ligament of the knee extends between the anterior portion of the tibial plateau and the inner surface of the condyles of the outer femur. The basic function of the ligament is to prevent anterior sliding of the subfemoral tibia and to control the rotational stability of the subfemoral tibia during knee flexion. [0004] An ACL tear causes instability of the knee and subsequent risk of dislocation. Treatment for a torn ACL may involve surgery or functional correction. [0005] Surgical treatment includes, for example, reconstruction of the anterior cruciate ligament using grafts from the tendon. [0006] Functional correction involves muscle comp...
