A structural element having a crescent-shaped side support with a D-shaped cross-section and a hemisphere at its ends; its sloping-edge shape and the visco-elastic material of which it is made allow it, once it has been arranged laterally to the patella and subjected to adequate medial traction, to adapt to the anatomical shape of the patella. Two belts of inelastic material are structurally integrated with the support at its ends and can be orientated through an arc of 45°, allowing to apply a direct and adjustable traction to the support, thus producing medializing forces on the patella which is functional to correct the different patterns of patellar instability. In order to keep the orthesis in place whilst it is being worn and avoid the loss of alignment with the patella during use, a strip of viscous material has been applied to the upper edge of the internal wall of the invention; the material, when rested on the skin, has a non-slip effect even with intense perspiration.
