One brace. Engineered, not sourced.
Mrjoint makes one product: an open patella knee brace built around four independently adjustable straps and four spiral spring stabilizers. It stays where you put it, and it gives something back when you stand. Over 100,000 sold.
What a two-strap brace can’t do
A conventional brace anchors in two or three places, so the only way to make it hold tighter is to make it squeeze harder. Mrjoint anchors in four, and the support comes from the structure instead.
Four-Strap Cross-Torsion System
Four independently adjustable straps create four anchor points that pull against each other. The brace holds firmly without being cranked tight.
Four Spiral Spring Stabilizers
Two flexible metal springs on each side. They store energy as the knee bends and release it as you straighten, so standing up takes less out of you.
Silicone Grip Strips and an Open Back
Double-layer silicone strips grip the leg instead of sliding on it, and the open Comfort Gap behind the knee means nothing bunches and nothing traps heat.
