The Bionic Fullstop Knee Brace provides the ultimate in ACL (Anterior Cruciate Ligament) protection during recovery from injury, as well as prevention of future injury. The brace protects athletes against lateral forces that can threaten an unstable or recovering joint. Fullstop dampening hinges prevent hyperextension and help improve joint mechanics in both surgical and nonsurgical knees. Through the dampening cycle of the hinge, muscle memory trains the body to keep both the braced and unbraced knees out of the at risk zone. The brace restricts damaging movements and absorbs impact energy, while offering a responsive and natural feel. The brace is perfect for anything from ACL injuries to ligament and tendon sprains to hyperextension and patella instability.
