Détails du produit

The innovative load-dependent adjustable brake mechanism offers targeted safety for the patient. Heel strike activates the brake which in turn provides high stability in the stance phase. The amount of stance flexion provided by the 3R90 is affected by adjusting the brake.

The swing phase can be controlled by means of a mechanical extension assist which, integrated in the lower section of the joint, has a progressively acting spring combination. Two combined spring elements form the integrated mechanical extension assist of the 3R90. The interaction of the springs results in an extension assist effect dependent on the knee angle. Extension assist can be preset to one of five different levels by means of a ratchet unit.
When fitting users with mobility grade 1, the following applies: these knee joints with friction brake are contraindicated for unsure patients who are unable to systematically use the braking mechanism during the gait cycle i.e. to lock the knee joint at heel contact and unlock it when the forefoot is loaded.
