The Ultra Cell knee protection system is without question the
most technologically advanced knee protection system available.
Several patented revolutionary design concepts come together in
unison to create this System.
Adjustable Retention Control, multiform cuff is just one of the many ways we have made the system truly supportive and customizable. The rigid lateral arms of the A.R.C. Cuff contain the lateral side of the thigh and calf, offering great protection against lateral blows. And in addition to giving the brace adjustability, the A.R.C. Cuff offers rigidity at the same time. How is all of this achieved? Two stainless steel tendon strips separately run the length of the cuff. As the adjustment screw is tightened, the rotary action of the screw threading through the tendon strip causes it to shorten. At the opposite end of the adjustment screw, the tendon strip is securely connected to the end of the cuff, causing the strip to "arc" in the direction of least resistance. Slightly pre-arced toward the leg when placed into the cuff body, the tendon strip directs the path of least resistance toward the leg. In other words, as you tighten the cuff, rigidity is dramatically increased as it wraps securely around your calf and thigh. In the event of a lateral blow, the the force is directed into the lower cuff. The force is then triangulated back into the brace. The force runs back across the frame to the medial hinge and then back again into the upper cuff. The force that would have been directed into the knee joint is now disbursed through the brace.
To ensure proper fit, circumference measurements should be taken directly on the skin with the leg straightened, using a soft tape measure. (If a soft tape measure is not available, a piece of string or yarn may be used to calibrate the leg's diameter, then measured against a hard tape measure.)
Locate the middle of the kneecap and measure around the leg. Measurements should be taken directly on the skin with a straight leg.
