GeoFlex Knee


The GeoFlex Knee is a friction-controlled polycentric knee, created for amputees who need stability but do not want a manual locking knee.

Amputees experience stability for up to 20 degrees of flexion under load, and feel secure and confident with each step. This knee accommodates a hip flexion contracture without giving up knee stability and allows for easier cosmetic finishing. A built-in Stance Flexion feature allows for a natural bending motion at the knee, creating a smoother stride. The roller bearing design allows for increased durability and longevity, while a more refined friction adjustment creates more stability and is much easier to use. The knee has a 4-hole pattern on the proximal end and a 30 mm tube connection at the distal end. The GeoFlex Knee comes with a stance flexion bumper replacement kit, dust cover, and an elastic extension assist.
