Description

Functional Footwear for Degenerative Osteoarthritis of Knee Joint}

The present invention relates to a functional shoe for a degenerative knee joint, and more specifically, to form a sole of the functional shoe for a degenerative knee joint by geometrically correcting the O-shaped leg or X-shaped leg while the wearer is walking without any treatment. The present invention relates to functional shoes for degenerative knee joints that can prevent and prevent pain of knee arthritis.

The knee joint is a part that balances the weight of the body that a human must support with four feet, but with 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 diseases caused by such degenerative changes or external shocks are as follows.

Meniscus damage that results in cracks in the meniscus in the knee due to extreme exercise or overweight, trauma, knee ligament injuries caused by strong impact or excessive rotation of the joints, Patellar cartilage that occurs frequently in young women, knees Inflammation of the bursal sac in the joint 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 greater compressive load acts on the inside of the knee than when the feet are supported. Due to this internal motion, the shin and thighs rotate inwardly of the knee, causing a load-bearing motion repeatedly during walking. If such mechanical phenomenon is accumulated, since the 40's do not do lower leg strength strengthening exercise gradually transformed into O-shaped legs, the ankle dorsal flexion range of the ankle is also reduced, the pace and stride length is reduced. 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.

Particularly, in women, the age and frequency of knee arthritis is lower than men because of the life patterns that frequently use childbirth and 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 is concentrated in the knee joint for a long time. From these results, it is possible to derive the result that pain relief and prevention of degenerative knee arthritis can be prevented by dispersing the biased concentrated load.

To achieve this effect, a shoe is placed on the outer surface of an existing orthopedic shoe insole or shoe sole, and the foot is put on the ground while the shoe is put on the ground. The method of causing the rotational force to move inward is 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 was created in order to solve the above problems, by geometrically forming the sole of the functional shoe for the degenerative knee joint to correct the O-shaped leg or X-shaped leg while walking without any treatment, knee arthritis The purpose of the present invention is to provide functional shoes for degenerative knee joints that can prevent and alleviate pain.

An object of the present invention as described above is a shoe made of an outer shell and a sole, the sole is degenerative, characterized in that at least a portion of the longitudinal central axis of the upper surface and the longitudinal central axis of the lower surface is deflected from each other in the longitudinal direction By functional shoes for the knee joint.

Here, the deflection width of the central axis of the upper and lower surfaces of the sole may vary along the longitudinal direction of the sole, and the deflection width of the sole is maximum in the central region of the longitudinal direction of the sole.

In addition, the deflection width is characterized in that 0 in the front and rear of the shoe.

In addition, the one end surface of the sole is biased in the upper surface and the lower surface is characterized in that formed in a parallelogram shape.

In addition, the one end surface of the sole is biased the upper surface and the lower surface is characterized in that the upper surface and the lower surface is connected by a plurality of partitions inclined at an angle of 0 ° to 90 °.

Soles having the above-described configuration is characterized in that at least one of the insole, midsole and outsole.

According to the present invention, by uniformly distributing the load applied to the knees, the O- and X-legged legs are naturally corrected during walking, thereby relieving the pain of degenerative knee arthritis, and preventing them.

As the O and X legs are corrected, there is an effect of correcting the overall skeleton of the wearer by establishing a correct gait and correct body structure.

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

Functional shoes for the degenerative knee joint according to the present invention generally consists of an outer shell (not shown) and the sole 100 covering the upper side of the sole 100 and the instep of the wearer. Here, the configuration of the sole 100 according to the present invention is characterized as follows.

<Configuration of the sole>

1a shows a plan view of the sole according to the invention which is deflected entirely along the longitudinal direction, and FIG. 1b shows a plan view of the sole according to the invention with a part deflected along the longitudinal direction. The sole 100 of the functional shoe for the degenerative knee joint according to the present invention is made so that the longitudinal central axis 111 of the upper surface 110 and the longitudinal central axis 121 of the lower surface 120 are deflected from each other. This deflected portion may be entirely deflected along the longitudinal direction of the sole 100, as shown in FIG. 1A, and only one portion may be deflected, as shown in FIG. 1B. In addition, the deflection width (L) and the thickness of the sole 100 is deformable in consideration of the bending state of the wearer's leg or preventive effect, and can be replaced in the course of treatment. Examples of such sole 100 will be described in detail below.

(First embodiment)

Figure 1b shows a plan view of the sole according to the invention, Figure 2 shows a partial longitudinal cross-sectional view of Figure 1 according to a first embodiment of the invention. 1 and 2, the deflection width L of each portion changes along the length direction of the shoe.

As shown in Figures 2a and 2e, the longitudinal section of the longitudinal front and rear portion of the sole 100 is the same as the general sole 100, the upper surface 110 and the lower surface 120 of the sole 100 is It is not biased. 2A and 2E, the portion where the upper surface 110 and the lower surface 120 of the sole 100 are not deflected is preferably about 10% to 30% of the total length of the shoe, respectively, in the front and rear portions. However, as shown in FIGS. 2B to 2D, the longitudinal central axis 111 and the lower surface 120 of the upper surface 110 of the sole 100 move toward the center region along the longitudinal direction of the sole 100. Deflection width (L) formed by the longitudinal central axis 121 of the) is gradually increased. That is, the deflection width L is zero at the front and rear portions of the sole 100 in the longitudinal direction, and the deflection width L is at the maximum in the longitudinal center region of the sole 100. In addition, the deflection width L is greater in the longitudinal center region of the sole 100 as compared with the deflection width L of the longitudinal front and rear portions of the sole 100. At this time, the deflection width (L) may vary in the longitudinal front portion, the central region and the rear portion of the sole 100 according to the walking pattern and the condition of the wearer. The shape of the longitudinal section of the deflected portion of the sole 100 is formed to be inclined inward or outward of the shoe in a two-step staircase shape.

In order to correct the leg of a person who is an O-shaped leg, the lower surface 120 is biased toward the outside of the human body based on the upper surface 110 of one side in the longitudinal direction of the sole 100. At this time, the deflection width (L) of the upper surface 110 and the lower surface 120 of the sole 100 can be changed according to the degree of bending of the wearer's legs, the upper surface of the sole 100 for wearing of the normal person ( Based on 110, the deflection width L of the lower surface 120 may be formed to be close to zero to prevent deformation of the leg in advance. When the sole 100 receives the weight because the longitudinal central axis 111 of the upper surface 110 of the sole 100 and the longitudinal central axis 121 of the lower surface 120 are deflected, the sole 100 By virtue of the geometrical shape of the force generation treatment method is naturally implemented. In this configuration, the wearer generates a moment of movement toward the center of the body while walking, the lower leg is inclined inward by the occurrence of the right force, and a gap between the joints of the knee is opened to reduce the load, and gradually O-shaped. Legs are straightened to eleven.

Figure 3a shows a schematic diagram showing the generation of the abduction moment of the conventional shoe, Figure 3b shows a schematic diagram showing the generation of the abduction moment of the shoe according to the present invention. As shown in FIG. 3A, the abduction moment generated by a general conventional shoe can be obtained by Equation 1 below.

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 during walking.

The abduction moment generated by the functional shoe for the degenerative knee joint according to the present invention shown in Figure 3b 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 moved ground reaction force vector axis (a '), d ₁ is the vertical distance between the center of the knee and the ground force force vector axis (a), 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], since M2 has a shorter abduction moment than M1, the rotational force for moving the knee and lower leg outward is reduced, so that the anterior pain in front of the knee is alleviated, and the O-shaped leg is reduced. Has the effect of being corrected.

In addition, in order to correct the X-shaped leg, the longitudinal central axis 121 of the lower surface 120 is longer than the upper surface 110 longitudinal center axis 111 of the sole 100 as opposed to the O-shaped leg. It is formed so as to deflect. If the sole 100 is made of such a configuration, the wearer has a right side to the outside of the body during walking. By this right force, the gap between the outer knee joint is widened to reduce the load acting on the outer knee, and the X leg is gradually corrected to eleven.
