KHP3

The KHP3 is characterised by the 5-axle design. The profile of the joint is suited to moderately active users with long above-knee or knee disarticulation prostheses who require a high degree of safety.

As a provisional prosthesis the joint can be set initially for relatively inactive patients and then adjusted in line with the progress made in mobility during rehabilitation.

The joint also secures the prosthesis during small steps, such as those taken when turning around on the side of the prosthesis, when walking up and down stairs, and on uneven ground.

The stance phase stability of the joint is determined by the closing geometry. Control of the swing phase is actively supported by the high-performance pneumatic mechanism. Flexion and extension can be adjusted separately to meet the individual needs of the user.

The 5-axle construction enables the prosthesis to be assembled without shortening in order to minimise possible long-term sequela such as intervertebral disk problems, knee problems in the existing leg and in the existing skeletal structures. The configuration of the geometry also enables the user to stand safely and comfortably. In addition, cosmesis stretching during sitting is reduced.


Technical information

   offset possible up to 5 mm AP/ML
   separately adjustable flexion and extension of the pneumatic system
   5-axle construction permits assembly without shortening
   closing geometry permits very easy release at the dorsal stopper and locking, even when taking small steps, for high stance phase stability
   integrated AP shift with the joint extended for comfortable standing on the prosthetic leg
   adjustments of up to 10° in flexion/extension and abduction/adduction possible
   high-performance pneumatics constructed for effectiveness similar to hydraulics
   ideal joint for knee disarticulation patients because the head of the joint shifts posteriorly during flexion (cosmetic effect)
