Footwear Having Functional Base Plate of Shoes for Degenerative Osteoarthritis of Knee Joint}

The present invention relates to a shoe having a functional sole for a degenerative knee joint, and more particularly, a longitudinal section of an insole or a midsole made of an insole or an integral sole of a shoe sole is either an inner side or an outer side of the sole and an outer surface of the sole. The degenerative knee joint, the other side of which is opposite to the angle of the outer surface of the sole, is smaller than the angle of the sole, that is, the inner or outer sides are not parallel to each other to correct the O-shaped or X-shaped legs. It relates to a shoe having a functional sole for.

The knee joint is a part that balances the weight of the body that a human must support with four feet and supports upright and walking without falling down. Therefore, even when we are not aware, we move little by little and adjust the weight so that it does not go out of the center of the knee joint. However, it is also the site where degenerative changes occur best as you get older because you are constantly gaining weight. The types of knee joint disease caused by such degenerative changes or external shocks are as follows.

Meniscus damage due to severe movement or overweight, trauma, meniscus cartilage in the knee, knee ligament injury caused by strong impact or excessive rotation of the knee, patella chondromalacia frequently occurs in young women, knee joint Inflammation of the bursa of the bursal ulcers, such as bursitis is a disease that occurs frequently in the knee joint.

Degenerative knee osteoarthritis may cause pain in the knee when standing up, trembling of knees when standing up, sound when bending or extending the knee joint, severe pain when one or more fists are open between the knees in a standing position If you experience symptoms such as pain after walking for two to three days, you should suspect it.

Joints move under load, especially the joints of the legs, such as the knees, where many times the weight is exerted by daily movements such as standing, walking, and climbing stairs.

Degenerative arthritis usually occurs in the fifties, but knee arthritis occurs frequently in the forties, a relatively early period. Treatment of arthritis aims at reducing pain and increasing joint flexibility, but it is difficult to cure because it is difficult to eliminate the cause of the original onset. In the case of mild symptoms, pain and symptoms can be alleviated through continuous physical therapy, medication, and weight loss, and severe arthritis can be alleviated through surgery. For example, total knee arthroplasty removes the knee joint with severe arthritis and implants a new joint. Patients with knee arthritis must continue to receive these treatments for a long time in order to be free from pain. However, due to the hassle and cost burden of treatment, many people do not receive proper treatment and live with pain.

If the human body supports both feet, the center of gravity of the human body crosses between the two feet, so that a greater load is applied to the inside than the outside of the knee joint. In addition, during foot support, the ground reaction line passes through the center of the foot and the center of the pelvis, so that the ground reaction force due to the weight is deflected from the center of the knee to the inside of the body. Therefore, a larger compressive load acts on the inside of the knee than when the feet are supported. When the load is accumulated on the medial knee joint, the muscles are gradually transformed into O-shaped legs after 40's, unless the muscle strength strengthening exercise is performed. There is a problem. The incidence of knee joint disease is about 12% of the total population, 60% of people over 60 years old, and 80% of people over 75 years old.

In particular, women have lower age and frequency of knee arthritis than men due to the birth patterns and lifestyle patterns that frequently use knee joints and the physiological changes of menstruation each month. You will bend and walk.

Degenerative knee osteoarthritis can be analyzed as a phenomenon in which the load of the degenerative knee osteoarthritis is medial anterior and transformed into O-legs after 40 years of age. From these results, it is possible to derive the result that the pain of degenerative knee arthritis can be alleviated and prevented by dispersing the biased concentrated load.

1 shows a schematic longitudinal cross-sectional view according to a conventional shoe sole. Conventional shoe soles are formed such that both the inner and outer sides of the sole are vertical or inclined at the same angle as the outer ground of the sole, as shown in FIG. Therefore, there is a problem that can not distribute the concentrated load.

In order to solve this problem, by putting a shoe on the outer surface of the conventional insole or shoe sole, putting the foot on the ground after putting the shoes on, the feet and legs themselves are inward according to the insole and sole inclination and the knee joint A method of causing a rotational force to move the inner side has been used. However, in the conventional method, since the foot slips inward due to the inclination of the shoe sole during walking, shearing force is generated, and excessive force is applied to the inner part of the foot and the knee to prevent the foot from slipping. This action has a problem that degenerative knee arthritis worsen.

In addition, conventional orthopedic formulations require custom prescription by a doctor's prescription to prevent the occurrence of side effects, and there is a problem that serious side effects occur if not adhered to.

Therefore, the present invention has been created to solve the above problems, the longitudinal section of the insole or midsole made of insoles or integral soles of the shoe sole is opposed to the angle of which one side of the inner or outer surface is formed with the outer surface of the sole Equipped with functional soles for degenerative knee joints, the other side of which is smaller than the angle of the outer surface of the sole, that is, the inner or outer bilateral sides are not parallel to each other to correct O- or X-shaped legs. The purpose is to provide a shoe.

An object of the present invention as described above is in a shoe comprising a sole and a sheath including at least one of the insole, midsole and outsole, insole or integrally formed insole or midsole of the sole, the end surface of the insole and the midsole are mutually opposite sides The functional sole for degenerative knee joints, characterized in that the angle between one side of the inner or outer side with the outer surface of the sole is less than the angle between the other side opposite to the outer surface of the sole so that it is not parallel. It can be achieved by the provided shoes.

Here, the longitudinal section of the sole or the sole insole and midsole of the sole is the angle of the inner surface with the outer surface of the sole for the wearer of the O-shaped knee than the angle of the outer surface with the outer ground of the sole. It is formed small. In addition, the angle formed by the outer surface with the outer surface of the sole is smaller than the angle formed by the inner surface with the outer surface of the sole for wearing by a person having an X-shaped knee.

Insoles and midsoles made of insoles or integrated soles may be replaced by changing the inclination angle and thickness according to the wearer's condition.

In addition, the outer shell is provided so that the insole and the midsole are not exposed to the outside.

According to the present invention, by uniformly distributing the load applied to the knee to correct the O-shaped legs and X-shaped legs during walking, the pain of degenerative knee arthritis is relieved, and there is an effect that can be prevented in advance.

Correction of the O-shaped leg or X-shaped leg establishes the correct gait and correct body structure, which has the effect of correcting the overall skeleton of the wearer's body.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

<Configuration of Shoes with Functional Soles for Degenerative Knee Joints>

Figure 2 shows a longitudinal cross-sectional view of a shoe with a functional sole for the degenerative knee joint according to the present invention. As shown in FIG. 2, the shoe 10 according to the present invention includes an outsole 200 and an outer shell 100 formed of an insole 210, a midsole 220, and an outsole 230. Here, the outer shell 100 is provided so that the insole 210 and the midsole 220 does not enter the outside, the detailed configuration of the sole 200 according to the present invention having the configuration features are as follows.

(First embodiment)

FIG. 3A shows a schematic longitudinal cross-sectional view of an outsole showing the force generated by the sole for wearing a person with an O-shaped knee, and FIG. 3B is a first view of the present invention for the wearing of a person with an O-shaped knee. The longitudinal cross-sectional view of the sole is shown in the embodiment. As shown in FIGS. 3A and 3B, the sole 200 according to the first embodiment of the present invention has an outer surface at an angle θ _in of which the inner surface forms the outer surface of the sole to correct the O-shaped legs. It is formed smaller than the angle (θ _out ) with the outer surface of the sole. At this time, the predetermined angle θ _in that the inner surface of the sole 200 forms with the outer ground may be inclined at an angle of 45 ° to 120 °.

FIG. 3C shows a schematic longitudinal cross-sectional view of an outsole showing the force generated by the sole for wearing a person with an X-shaped knee, and FIG. 3D is a first view of the present invention for the wearing of a person with an X-shaped knee. The longitudinal cross-sectional view of the sole is shown in the embodiment. On the other hand, in order to correct the X-shaped legs, the angle θ _out formed by the outer surface with the outer surface of the sole is formed smaller than the angle θ _in formed by the inner surface with the outer surface of the sole. At this time, it is preferable that the predetermined angle θ _out formed by the outer surface with the outer ground be inclined at an angle of 45 ° to 120 °. At this time, the predetermined angle (θ _in ,) When θ _out ) is less than 45 ° and exceeds 120 °, it is difficult to form a normal shoe. This angle of inclination (θ _in , θ _out ) can be changed according to the degree of bending of the wearer's leg, and the angle of inclination (θ _in ,) θ _out ) can be formed close to 90 ° to prevent deformation of the legs. One side of the midsole 220 has a predetermined angle (θ _in , θ _out ) Because it is tilted, the traditional treatment method is naturally implemented by the geometry of the midsole 220 when the sole 200 receives weight.

Insole 210 of the sole 200 for straightening the O-shaped leg 210 or the insole 210 and the midsole 220, as shown in Figure 3a, the right to move the knee to the center side of the body during walking ( Moment) is generated, the gap between the joints inside the knee is opened by the occurrence of the right force, and the load is reduced, and the O-shaped leg is gradually corrected to 11-shape.

Figure 4a shows a schematic diagram showing the abduction moment of the conventional shoe, Figure 4b shows a schematic diagram showing the abduction moment of the shoe according to the present invention. As shown in Figure 4a, the abduction moment generated by the general conventional shoes can be obtained by the following equation (1).

M ₁ = d ₁ × F

Here, M ₁ is the abduction moment, d ₁ is the vertical distance between the center of the knee and the ground reaction force vector axis (a), F is the ground reaction force generated on the ground when walking.

As shown in Figure 4b, the abduction moment generated by the shoe 10 according to the present invention can be obtained by the following equation (2).

M ₂ = d ₂ × F = (d ₁ -e ₁ ) × F

Where M ₂ is the abduction moment, d ₂ is the vertical distance between the center of the knee and the ground repulsion force vector axis (a '), d ₁ is the vertical distance between the ground repulsion force vector axis (a) and the center point of the knee, e ₁ is the vertical distance between the ground repulsion force vector axis a and the moved ground repulsion force vector axis a ', and F is the ground repulsion force generated on the ground during walking.

As shown in [Equation 1] and [Equation 2], because M2 has a shorter abduction moment than M1, the rotational force for moving the knee and lower leg outward is reduced, thereby alleviating the internal pain in the front of the knee, and O-shaped. Legs are corrected.

In addition, the insole 210 of the sole 200 or the insole 210 and the midsole 220 of the sole 200 for correcting the X-shaped legs are opposite to the O-shaped legs, as shown in FIG. The force to move out of the body occurs. This superior force opens the gap between the outer knee joints and reduces the load acting on the outside of the knees, and the X leg is gradually corrected to eleven.

5 is a longitudinal sectional view of the shoe according to the modification of the first embodiment of the present invention. As shown in FIG. 5, the insole 210 or the insole 210 and the midsole 220 made of the sole 200 may be formed to round both sides. In addition, the shell 100 may be coupled between the outsole 230 and the midsole 220.

(Second embodiment)

Figure 6 shows an exploded perspective view of the sole according to a second embodiment of the present invention, Figure 7 shows a longitudinal cross-sectional view of the sole according to a second embodiment of the present invention. The configuration of the insole 210 or the insole 210 and the midsole 220 of the sole 200 according to the second embodiment of the present invention or integrally as shown in Figure 6 and 7, the first embodiment as a whole It is composed of a similar configuration.

However, a groove 231 of a predetermined depth is formed along the outer circumferential surface of the sole 200 on one upper side of the outsole 230. The height of the groove 231 is preferably formed to be lower than the thickness of the midsole 220. In addition, the width of the groove 231 is preferably formed to a width that can be inserted into the lower one side of the midsole 220.

8 is a longitudinal sectional view of a shoe according to a modification of the second embodiment of the present invention. As shown in FIG. 8, the sole 200 having the same configuration as the second embodiment described above may be formed to round one side surface perpendicular to the ground. In addition, by forming a protrusion 232 along the outer circumferential surface of the outsole 230 on the top surface of the outsole 230 may be coupled to the shell (100).
