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.

Description

BACKGROUND OF THE DISCLOSURE[0001]a) Field of the Disclosure[0002]The invention relates to a device for improving walks of a patient with knee osteoarthritis, and more particularly, to a device for improving walks of a patient with knee osteoarthritis, wherein the device can reduce knee varus torques.[0003]b) Brief Description of the Related Art[0004]Knee osteoarthritis is a common musculoskeletal disorder. A patient having a worn cartilage in patient's joint will cause abnormal proliferation of its surrounding bones and cause a joint cavity to become narrow. This would lead patient's joint when being in motion to have pain and lead the patient's independence to be reduced. According to the biomechanics, when walking, a patient with knee osteoarthritis has relative great knee varus torque. This would lead knee arthritis to be dramatically deteriorated. Therefore, knee varus deformity would happen to a severe one.[0005]According to the statics of population over the age of 50 in Taiw...

AI Technical Summary

Benefits of technology

This invention is a device designed to improve the walks of patients with knee osteoarthritis by reducing knee varus torires. It includes an insole with a wedge cushion joined at the forefoot and hindfoot, and a medial-foot-arch cushion that increases walking stability and reduces joint pain. The device is simple and low-cost, and easy to use. Its wedge shape improves the transfer of reaction force and reduces loading on the knees, slowing down the progression of knee arthritis.

Problems solved by technology

A patient having a worn cartilage in patient's joint will cause abnormal proliferation of its surrounding bones and cause a joint cavity to become narrow.

This would lead knee arthritis to be dramatically deteriorated.

Even though reducing loading of a knee joint during a heel contacting period, this design could result in excessive pronation movement of a foot during a long-standing period or forward-moving period.
