Outfitted with anatomically correct Accutrac hinges and flexible cuffs and buckles, the rock-solid CTi carbon frame provides a rigid exoskeleton that stabilizes the knee joint. Breathable liners coated with bio-inert Ossur Sensil Silicone ensure CTi remains properly positioned on the leg, for optimal functional benefit.

Also referred to as our off-the-shelf (OTS) model, CTi comes in a range of 5 frame sizes. Each brace includes a set of condyle pads, wedge pads and extension stops that can be mixed and matched to achieve the best possible fit. For a truly custom brace, ask your healthcare provider about the CTi Custom.

The standard and Pro Sport models differ only in the amount of carbon fiber used in the frame. The more carbon fiber used, the more rigid the brace. The less carbon fiber used, the lighter the weight. Which option is best for you will depend on your individual body proportions and activity requirements.

Standard - The choice of most pro athletes and the best compromise of weight and impact resistance, CTi standard is the best option for 95% of body types and activity levels. From low impact lifestyle uses to high impact applications like motocross and wakeboarding, the standard CTi is the built for athletes and casual users alike.

Pro Sport - The most rigid option for the largest of users. Pro Sport is built with the most carbon fiber to accommodate much larger frames. Pro Sport wears heavier and more rigid than standard, and will only be applicable to users with larger body mass who require a sturdier brace to avoid migration on more cone shaped legs and higher durability under strain. Only 5% of users will require this level of rigidity, ideal for support, not for motion.

PCL Version - For users with PCL instability, the extra PCL support version of the brace has additional supports for the thigh and calf. Strap kit can also be purchased separately by vising this page here.

Warranty Information: Ossur warrants the frame and hinge components to be free of defects in materials and workmanship for 2 years. Straps, liners, return cords, hinge coating and other soft components shall be warranted free from defects in materials and workmanship for 6 months.
