Abstract
A patella exercise device for continuously exercising the patella during continuous passive movement of the knee includes a patella contact pad mounted to a (CPM) device for contacting the patella while the knee is moved in flexion and extension by the (CPM) device. The patella contact pad is adapted to contact and push the patella from a neutral anatomical position during operation of the (CPM) device. Depending on the positioning of the patella contact pad with respect to the patella, the patella is either pushed superiorly or inferiorly during flexion and extension of the knee. The patella is then compressed and tightened during the opposite movement. The patella contact pad may be driven by a spring like cam member to exert a predetermined force against the patella. The patella exercise device is useful for therapy of a knee following injury or surgery and helps prevent patella baja.
