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 features
  • Relief of the lateral or medial compartment using the 3-point principle
  • Pain relief by reducing weight-bearing on the affected side of the joint
  • Optimal stabilisation using 4-point principle
  • Safe collateral stabilisation by riged Frame
  • Extension and flexion limitation protects against damaging joint movements and relieves injured structures
Intended purpose

M.4s OA comfort is a brace with a frame designed for relieving load on and stabilising the knee joint.


All indications that require load relief of a compartment via the 3-point principle, physiological support and stabilisation in accordance with the 4-point principle and, where required, limitation of the range of motion of the knee joint, such as:

  • Severe medial or lateral compartment osteoarthritis (class III at least) in conjunction with complex ligament instability.
  • Before HTO (corrective osteotomy) for unicompartmental load relief (brace test)
  • Following cartilage surgery or cartilage regeneration
  • Following surgical intervention on the meniscus
  • Bilateral osteoarthritis of the knee
