Donjoy Performance Bionic Fullstop Knee Brace

The DonJoy Performance Bionic FullStop Knee Brace is engineered for athletes who demand high-performance knee protection during sports or high-impact activities. Designed for both injury prevention and recovery, this hinged knee brace delivers superior stability for ACL injuries, meniscus tears, moderate ligament sprains, hyperextension prevention, and patella support.

The Bionic FullStop's fullstop dampening hinges and four-point leverage system train your muscles to avoid "at-risk" positions, improving joint mechanics in both surgical and non-surgical knees. Anti-migration technology and adjustable straps ensure the brace stays secure during explosive movements, while compression and thermal regulation maintain comfort during long workouts or games.

Ideal for football, basketball, soccer, lacrosse, skiing, snowboarding, and other high-impact sports, the Bionic FullStop combines performance, protection, and mobility in a sleek, low-profile design.

How It Works

The Bionic FullStop uses dampening hinges that engage during extension to prevent hyperextension, a common cause of ACL tears. The four-point leverage system works with the hinges and straps to stabilize the knee and reduce lateral stress. Through repeated movement, the brace helps train muscle memory so the knee naturally avoids "at-risk" positions.

Compression and thermal regulation materials provide additional comfort and circulation support, while anti-migration technology ensures the brace stays in place during sports, agility drills, or everyday activity.
