Walking device for improving patient with knee osteoarthritis

Abstract

A device for improving walks of a patient with knee osteoarthritis includes an insole, an inside-forefoot wedge cushion joining the insole at an inner side of a forefoot, wherein the inside-forefoot wedge cushion can support the inner side of the forefoot and thus reduce knee varus torques, an outside-hindfoot wedge cushion joining the insole at an outer side of a hindfoot, wherein the outside-hindfoot wedge cushion can support the outer side of the hindfoot and thus reduce knee varus torques, and a medial-foot-arch cushion joining the insole, wherein the medial-foot-arch cushion can have a foot to be turned out and increase walking stability and fluency. Thereby, a patient with knee osteoarthritis, when being walking, can have reduced knee varus torques. The purpose of improving walks of a patient with knee osteoarthritis can be achieved.

What is claimed is: 
     
         1 . A device for improving walks of a patient with knee osteoarthritis, comprising:
 an insole;   an inside-forefoot wedge cushion joining the insole at an inner side of a forefoot, wherein the inside-forefoot wedge cushion is configured to support the inner side of the forefoot and thus reduce knee varus torques;   an outside-hindfoot wedge cushion joining the insole at an outer side of a hindfoot, wherein the outside-hindfoot wedge cushion is configured to support the outer side of the hindfoot and thus reduce knee varus torques; and   a medial-foot-arch cushion joining the insole, wherein the medial-foot-arch cushion is configured to have a foot to be turned out and increase walking stability and fluency.   
     
     
         2 . The device of  claim 1 , wherein the insole is a hard form. 
     
     
         3 . The device of  claim 1 , wherein the inside-forefoot wedge cushion has an inclining angle ranging from 5 degrees to 10 degrees based on user's needs. 
     
     
         4 . The device of  claim 1 , wherein the outside-hindfoot wedge cushion has an inclining angle ranging from 5 degrees to 10 degrees based on user's needs.
