Description
The DONJOY 4Titude Advanced CI knee brace, gray, provides targeted support for your knee joint in cases of instability and after injuries. This torsion-resistant frame brace provides reliable guidance, secure support and controlled movement without unnecessary bulk. It is ideal for anyone who needs greater confidence in everyday life or during rehabilitation and values an anatomical fit and individually adjustable range-of-motion control.
The DONJOY 4Titude Advanced CI knee brace, gray, uses the proven 4-point principle to stabilize the knee where it matters: it helps reduce unwanted shear forces and guide the joint along a physiological path. The polycentric joint supports natural knee movement, while the anatomically contoured, low-profile frame made of aircraft-grade aluminum remains stable and can still be shaped to fit the contours of the leg. The medially angled thigh frame can also improve wearing comfort.
Practical for everyday use: Folding strap loops, a low-profile strap design and rubberized strap tabs make the brace easier to put on and ensure a secure fit. The shin pad with an opening can relieve pressure on the patellar tendon—an advantage when sensitive areas need to be relieved. Mobility can also be controlled precisely: With adjustable flexion and extension stops, the DONJOY 4Titude Advanced CI knee brace, gray, supports controlled movement during therapy, rehabilitation and periods when your knee needs additional guidance.
