Armor Fourcepoint Knee Brace

The Armor Fourcepoint line centers on rigid, hinged knee support engineered for people managing ligament instability, post-injury recovery, or chronic knee weakness who need more than a simple sleeve can provide. If you're weighing whether a hinged brace is worth it over a basic wrap, the difference comes down to controlled movement: the Fourcepoint's aluminum hinges guide the knee through a natural range while limiting the side-to-side and hyperextension motion that aggravates unstable joints.

Our current offering is the Armor Fourcepoint Knee Brace (Medium, Right Knee, 18-1/2 to 21 inch circumference) — a hinged, short-calf design built with an aluminum frame, breathable neoprene, and cushioning foam. The neoprene retains warmth to ease stiffness and support circulation, while the foam padding prevents the hinge hardware from digging in during extended wear. The short-calf length keeps the brace from bunching behind the knee, which matters if you'll be seated or bending frequently through the day.

Sizing is the question buyers get wrong most often. This brace is measured by circumference around the knee, not by shoe size or general clothing size — the medium fits an 18-1/2 to 21 inch measurement. Measure at the center of the kneecap with the leg slightly bent for the most accurate fit. Note that this model is knee-specific: it's shaped for the right knee, so confirm the side before ordering. A properly fitted hinged brace should feel snug enough to stay put during a walk but never so tight that it pinches or leaves marks.

The Fourcepoint suits recovery from sprains, mild ligament strains, and everyday activity where the knee needs reinforcement without full immobilization. For related protective and support gear, explore our Body Armor and BLACK ARMOR collections.
