Quality Protection Since 1983



CTi has been making headlines in action sports since its introduction in 1983. The creation of a motocross rider and skier, the first CTi prototypes helped athletes regain their freedom to ride after knee ligament injuries.

Today CTi knee braces are the knee protection of choice for professionals worldwide – from athletes to physicians – who need reliable, clinically proven knee ligament support and impact protection they can trust.

Total Ligament Support

CTi Knee Braces provide clinically proven knee ligament support and protection from potential re-injury.

Lower frame and upper cruciate strap capture the tibia and stabilize the ACL.

6 points of support stabilizes the MCL and LCL.

Upper frame and lower cruciate strap stabilize the PCL.

CTi locks onto the tibia and acts as an exoskeletal support and provides brace-to-bone contact that’s crucial for maximum stabilization of the knee joint.

The result is reliable stability and support that’s still low-profile, comfortable and stays in place.

Clinically proven to
help prevent re-injury
after ACL surgery


In a study of ACL-deficient skiers, skiers braced with a CTi Knee Brace had 6.4 times less risk of subsequent knee reinjury than non-braced skiers.¹ ²
