CROSS™ is a semi-rigid knee orthosis intended to be used when knee hyperextension in the knee joint is present. CROSS™ was developed and designed to function together with an Allard AFO (Ankle-foot-orthosis). No straps or buckles that intervene with the composite orthosis. The cross on the back stabilizes knee hyperextension.

The unique design makes it easy to put on and take off using only one hand. The orthosis has an ultra-smooth low friction liner with no visible seams that prevents skin irritation. The soft inside helps the orthosis to glide easily over the foot and up over the knee. To prevent migration the orthosis has a strategically placed silicone band.

The reinforcement in the upper wide cuff keeps the orthosis open so the foot and leg slide easily into the brace. This will help users with limited function put on the orthosis with only one hand. The “donning aid” further assists users with limited balance to guide the orthosis over the foot and pull it up on the leg.

CROSS™ has adjustable ROM stops. Flexion: 45°, 60°, 75°, 90° degrees and Extension: 0°, 10°, 20°, 30°, 40° degrees.
