The Defiance is unofficially known as the flagship brace of DonJoy. Its patented leverage system and lightweight, high-tech design make it the go-to brace for any sort of ligament instabilities. ACL, PCL, MCL, LCL. You name a ligament, the Defiance will handle it. While the Defiance may be lightweight, it is no slouch when it comes to durability and stability. Its carbon-composite build makes it perfect for high-impact sports like rugby, snow sports or football when protection is an absolute must. It’s also available with the LoPro FourcePoint Hinge, the only hinge clinically-proven to protect the ACL. It does all this with a low-profile design to keep it out of your way and under clothing or uniforms.
The Reaction, on the other hand, was designed for kneecap stability and anterior knee pain reduction. The brace’s elastomeric web design helps absorb pressure that would normally be felt on the patella and disperse it throughout the rest of your knee. It’s a fantastic brace if you have arthritis or tendonitis problems that could use the helping hand. The brace’s open web design and mesh backing lets your knee breathe comfortably unlike traditional elastic designs.
