Abstract
A knee joint rehabilitation assist device and associated methods are shown. A knee joint rehabilitation assist device includes a rigid frame, a heel rest attached across one end of the frame to accommodate a heel of a user, and a knee contact attached at a distance spaced from the heel rest. Adjustability of various components and a ratcheting pressure control provide gradual controllable pressure to increase range of motion in a knee joint.
Claims21
A knee joint rehabilitation assist device, comprising:
- a rigid frame having an adjustable length;
- a lower leg fixture at a distal end of the rigid frame;
- a knee contact between the distal end and a proximal end of the rigid frame, wherein the knee contact is movable within a range between the distal end and the proximal end;
- and
- a pressure control strap located at the proximal end of the rigid frame, the pressure control strap configured to control downward pressure to an upper surface of the knee through the knee contact when in use.

A method of rehabilitating a knee joint after surgery comprising:
- placing a heel rest located at a distal end of a rigid frame under a user's heel;
- placing a knee contact against the user's knee, wherein the knee contact is located between a distal end and a proximal end of the rigid frame;
- looping a pressure control strap around the user's leg at a location above the knee, the pressure control strap located at the proximal end of the rigid frame;
- adjusting a coarse adjustment of the pressure control strap to remove slack in the pressure control strap;
- and
- ratcheting a ratcheting adjuster on the pressure control strap to apply incremented pressure and to flex the knee joint.
