KNEE SUPPORT ORTHOSIS ADAPTED TO A PROLONGED SEATED POSITION

A knee orthosis including: a sleeve made of elastic fabric and configured to exert compressive forces on the knee, proximal and distal anchors for maintaining proximal and distal parts of the sleeve in fixed positions on the lower limb, and a panel including a viscoelastic layer of polymer gel fixed to an inner face of the sleeve, an annular part configured to surround the kneecap, and a distal tab, the viscoelastic layer having an adherence to the skin so, once stretched out longitudinally on the leg, the panel applies forces to the skin for supporting the kneecap, and the sleeve is formed from pieces of fabric including: a front piece supporting the panel, a rear piece and two lateral pieces, the rear and lateral pieces having moduli of elasticity in the axial direction which are respectively less than and greater than the modulus of elasticity of the front piece.
