Why Custom?
Because one size doesn’t fit all. And it definitely doesn’t fit you – because no one moves the way you do. DonJoy® custom knee braces are built to keep up with every move you make. They fit like they‘re built just for you – because they are. A specially trained bracing expert will personally measure and fit you. Using our advanced proprietary algorithms, we custom-make your brace with ultra-strong materials and quality craftsmanship to help protect you everywhere you wear it. So you can rehab, train and play with confidence.

4 Points of Leverage™
Run, jump, cut back or hold up. DonJoy’s 4-Points-of-Leverage System has you covered.
Clinically proven1 to help decrease ACL strain by at least 50%, our groundbreaking technology combines rigid anterior thigh and posterior calf cuffs with a strategic strapping sequence. This innovative design pushes the femur anteriorly and applies an active constant load to prevent anterior tibial translation and protect the ACL.

FourcePoint® Hinge
Get additional ACL protection with NO significant performance limitations.
DonJoy’s FourcePoint Hinge uses clinically tested hinge technology2 that helps train the knee to flex and increases flexion angles during cutting and jumping. Resistance engages in the last 25 degrees of extension to help keep the knee out of the at-risk position. And training effects are retained by about 50% even when you’re not wearing the brace.
