Functional elastic knee brace made of three-dimensional knitted breathable elastic fabric. It has no seams, which makes it comfortable to wear, avoiding annoying rubbing. In addition, its resistant textile material, reinforced at the extremities, offers adequate anatomical adaptation and durability. It has a viscoelastic patellar impeller with reinforcement for tibial protection and unloading of the patellar tendon. It allows adequate control of the trajectory of the patella and its relief points apply a micro-massage effect that favours the reabsorption of oedema and hematomas during knee movement. Spiral stabilisers for better mediolateral control and preventing the brace from rolling. With silicone dots inside to prevent migration during activity.
