Functional rigid brace with extension / flexion limitation

The M.4 X-lock is a functional knee orthosis. The product is exclusively to be used for the orthotic fitting of the knee and only on intact skin.

Product features
  • Reliable locking when fully extendes. As a result, axial loading is possible in the extended position
  • The compression resulting from the pressure promotes the stability of the meniscus suture
  • Due to the easy conversion during free movement, initial functional excercises are possible when the brace is not under a load
  • Muscle atrophy is prevented
  • Limitations:
  • - Extension limitation at: 0°, 10°, 20°, 30°, 45°
  • - Flexion limitation at: 0°, 10°, 20°, 30°, 45°, 60°, 75°, 90°
  • - Immobilisation at: 0°, 10°, 20°, 30°, 45°
Goal setting

Whenever possible, put on the knee brace in the extended position. To do so, set the knee brace to the extended position and lock both joints by moving the slider forward (you can see a red area in the windows on the joints).
Open all the straps. Sit on the edge of a chair and put the brace on. Position the brace so that the centre of the hinges (silver wedges) are on a level with the top edge of the kneecap. Make sure that the brace is not twisted on your leg.
First fasten the lower front strap, then the upper rear thigh strap. Position the two joints close to your joint towards the front of the leg.
Now fasten the lower rear thigh strap. Pull the joints slightly forward again. Make sure that you do not pull the joints in front of the midline of the leg.
Now fasten the upper front calf strap, then the upper back calf strap, and finally the front thigh strap.
