The DonJoy Armor knee brace is the brace to use if you are an extremely active individual or athlete who suffers from an ACL, MCL, or PCL instability or injury. The Armor brace is the strongest and most supportive brace you can get without a prescription. In fact, many collegiate football teams require their linemen to wear this brace because it is so successful at preventing ACL injuries. If you are concerned about preventing a ligament injury, try the DonJoy Armor knee brace. It is one of the best ways to minimize your chances of suffering from these painful injuries.
This brace is ideal for athletes who play football, ski, snowboard, ride motorcross, surf, wakeboard, or participate in similar high impact sporting activities.
