Knee brace for varus / valgus pressure relief

M.4s OA comfort is a varus / valgus offloading brace. The product is exclusively to be used for the orthotic fitting of the knee and only on intact skin.


Product benefits

  • Improved fit: The movable thigh shell adapts to a variety of thigh shapes, especially during movement.
  • A high level of comfort: Double-layered condylar pad-covers reduce friction on the skin as the two layers of fabric slide easily against each other.
