Description

Functional footwear for regressiveness knee joint flame

The present invention is directed to degenerative knee osteoarthritis which uniformly distributes the load applied to the knee joint to relieve the knee pain and to prevent the knee arthritis in a person suffering from degenerative knee arthritis or damaged by abnormal lower limb joint movement. It relates to a functional shoe for.

The knee joint is a part that balances the weight of the body that the human should support with four feet but can stand without falling with two feet, so it moves little by little even when we are not aware, and the weight passes the center of the knee joint. Therefore, the greater the load than the compressive force due to the weight continuously acting as the age is the site where the degenerative change is most likely to occur. In addition, meniscus injuries to the knee joint may be caused by meniscus damage due to severe exercise, overweight or trauma, meniscus cartilage cracking in the meniscus. It is becoming.

Degenerative knee osteoarthritis causes pain in the knees when standing up, trembling when standing, pain in bending or spreading the knees, and increased pain especially when climbing and descending stairs. As the disease progresses a bit more, the right posture turns into an O-shaped knee with one or more fists, and when walking down the stairs, the pain is particularly severe and the pain after walking lasts for 2-3 days or more.

The knee joint is a place where several times the weight is exerted by daily movements such as standing, walking, running, and moving up and down stairs. The knee is the joint that receives the strongest force among the joints of the body.

Degenerative arthritis usually occurs in the fifties, but knee osteoarthritis usually occurs in the early 40s.

Treatment goals for arthritis are pain relief and increased joint flexibility. However, most arthritis cannot be cured. In the case of mild symptoms, pain and stiffness can be alleviated through continuous physical therapy, drug therapy, and weight loss.Severe arthritis patients can reduce pain through arthroscopy and joint function through reconstruction You can also recover. For example, total knee arthroplasty is the operation of removing a knee joint with severe arthritis and replacing a new joint with a structure. Patients with knee arthritis must continue to receive this treatment to be free from pain. However, due to the hard work and cost of treatment, many people are suffering from pain without receiving proper treatment.

Figure 1 is an anatomical structural diagram of the lower extremity of the human body viewed from the front, Figure 2 is a view showing when the ground is supported by one foot when walking. As shown in Figure 1 and 2, when the two feet support the center of gravity of the human body (10) passes through the center between the two feet, the greater the compression load acts on the inside than the outside of the knee joint. When the foot is supported during walking, the ground reaction line passes through the center of the foot and the center of the pelvis, that is, the ground force caused by weight is biased from the center of the knee to the inside of the body. To act.

If the mechanical load is accumulated and the muscle strength strengthening exercise is not performed after the 40s, it naturally deforms into the “O” leg shape and the ankle dorsal flexion movement range is also reduced, which makes it difficult to walk vigorously and reduces the stride and stride length.

Especially in the case of women over 65, walking is uncomfortable in most people, and the legs are bent in an "O" shape, and the legs are walking. Women have a lower incidence and frequency of knee arthritis than men because of the birth patterns, overuse of the knee joints, and monthly menstrual changes. Men, on the other hand, are less likely to become "O" knees than women and appear at a higher age.

Clinical observation that degenerative knee osteoarthritis is anterior medial knee and transforms into a relatively "O" shaped knee after 40 years has been observed. This is consistent with the fact that a large compressive load acts on the inside of the knee. From this, degenerative knee arthritis is a phenomenon in which load is concentrated on the joint surface of the knee for a long time, and it can be seen that pain relief and prevention of degenerative knee arthritis is possible by dispersing the concentrated load acting in this deflection.

On the basis of the cause identification, the parallel quadrilateral shoe sole generates a moment that abducts the shin, thereby moving the knee inward, reducing the compressive load acting on the medial surface of the knee joint, and wearing the shoe without raising the heel. By shifting the center of gravity slightly backwards, the knee helps to perform daily activities and sports activities for increased joint flexibility and strength without feeling pain in the knee joint without undergoing surgery or ongoing physical therapy and medication. It becomes possible to develop functional shoes of therapeutic aids with pain relief and preventive functions of arthritis.

Shoe prescription for pain relief and prevention of degenerative knee osteoarthritis is similar to the method used to correct "O" knee and to control excessive supination of the foot in terms of its causes and symptoms. In the conventional orthopedic field, by putting a wedge on the outer surface of the insole or shoe sole, putting the foot on the ground, the feet and legs themselves are inward and the knee is moved inward according to the inclination of the insole and the sole of the shoe. We are using a method of generating rotational force.

However, in the conventional method, when walking in shoes, the shear force is generated because the foot slips inward due to the inclination of the sole of the shoe, and the excessive load on the legs and the inner part of the foot to prevent the foot from slipping causes a strong load on the knee. Because of this, degenerative knee arthritis may worsen, so be careful.

Due to the occurrence of these side effects, orthopedic formulations must comply with the prescription prescribed by the doctor's prescription, if not adhere to this can cause serious side effects due to the shear force is not accurate alignment.

Even if the shoe shape is not precisely tailored to each other without lateral shear forces, a new method is needed to distribute the concentrated load without any side effects to the human musculoskeletal system.Degenerative knee osteoarthritis visits the doctor's office Even if the shoes are not customized for each individual, they should be purchased in general stores so that they can wear them so that many people can benefit conveniently.

The present invention is to solve the problems as described above, by producing a shoe sole in a parallelogram shape, so that the foot does not slip inward or outward to generate a rotational force to relieve the pressure on the knee pain area without shearing force is degenerative The purpose of the present invention is to alleviate the pain of knee arthritis and to prevent or delay the development of degenerative knee arthritis when a normal person ignites it.

Another goal is to correct the wrong leg shape by varying the inclination of the parallelogram shoe according to the person with different lower extremity skeletal alignment.

In addition, there is another purpose to keep the body balanced and to walk safely.

The object of the present invention as described above is in the shoe, including the sole and the upper, the foot inside the knee for the case of a person having a major pain or being transformed into an "O" shaped knee or having an "O" shaped knee An insole 442 that is inclined to tilt 480; Shoe sole 440 inclined at a certain angle (α) from the ground so that the longitudinal cross-sectional structure when combined with the insole 442 to form a parallelogram except square and rectangular shape; for degenerative knee osteoarthritis, characterized in that It can be achieved by functional shoes.

As another category, the purpose of the present invention is to provide a shoe with soles and uppers in which the foot is inward (for people with major pain on the outside of the knee, being transformed into an "X" knee or having an "X" knee). An insole 442 that is inclined to tilt 470; Shoe sole 440 inclined at a certain angle (α) from the ground so that the longitudinal cross-sectional structure when combined with the insole 442 to form a parallelogram except square and rectangular shape; for degenerative arthritis It can be achieved by functional shoes.

The effects of wearing the shoes of the present invention are as follows.

1. Effect of correction of leg alignment when standing upright

Distance between knees Front image bare foot 176 mm

Shoes1 (General Shoes) 184 mm

Shoes2 (this shoe) 174 mm

When the person with the O-shaped leg wears the shoe according to the present invention, it can be seen from the image analysis that the knees are closer to each other than when the normal shoes are worn when supporting the feet. That is, the rotational force to move the knee inwardly acts to correct the lower extremity skeletal alignment in the form of a (I), thereby reducing the compressive force acting on the inside of the knee can be seen that the pain is reduced.

The following picture is an enlarged photograph showing the difference in the distance between the knees when wearing normal shoes (shoes 1) and shoes of the present invention (shoes 2).

Shoes1 (General Shoes)

Shoes2 (this shoe)

2. Effect of generating shin abduction rotation force when walking

Sole Pressure Distribution Shoe sole pressure distribution bare foot

Shoes1 (General Shoes)

Shoes 2 (this shoe)

Comparing the pressure acting on the soles and soles of shoes when walking with normal shoes (shoes 1) and the shoes of the present invention (shoes 2), the foot pressure decreases when the shoes are worn and walked, and the sole pressure is the body You can observe it moving inward. The movement of the shoe sole pressure to the inside of the body means that the foot rotates outward, and the outward rotation of the foot generates a rotational force that abducts the shin by the law of action-reaction. When the shin is rotated outwards, the gap between the medial part of the knee joint is widened and the compressive force is reduced, thereby reducing the pain in the inner part of the knee. In addition, the occurrence of knee arthritis can be prevented in advance.

In addition, in case of "O" shaped knee and "X" shaped knee where skeletal alignment is out of the normal, the shoes can be manufactured differently by using parallelogram shoe sole and traditional techniques in the field of orthopedic shoe. Wearing the right shoes can double the effect of correcting misalignment.

Correct leg morphology also establishes correct gait and correct body structure.

Other objects, specific advantages and novel features of the present invention will become more apparent from the following detailed description and the preferred embodiments associated with the accompanying drawings.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail. First, in adding reference numerals to components of each drawing, the same reference numerals are used for the same components as much as possible even if they are shown in different drawings. In addition, in the following description of the present invention, if it is determined that the detailed description of the related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

3A is a right lower limb alignment front view of an "O" shaped knee, and FIG. 3B is a right lower limb alignment front view of an "X" shaped knee. As shown in FIGS. 3A and 3B, the mechanical axis 50 represents a line connecting the center of the femur head to the center of the femur head, and the anatomical axis 60 of the femur is the line passing through the center of the femur and the flexion of the femur. The axis 70 is a line connecting the center of the femoral head and the knee joint, and the anatomical axis 80 of the tibia is a line passing through the center of the tibia.

Genu varum, commonly referred to as an "O" knee, refers to the case where the lateral angle formed by the anatomical axis of the femur and tibia is more than 180 degrees. Genu valgum, called the "X" knee, refers to the femur and the femur. The lateral angle formed by the anatomical axis of the tibia is 165 degrees or less.

As described herein, a person having an "O" shaped knee includes all those who are naturally born with an "O" shaped leg or a modified "O" shaped leg. In addition, a person with an "X" shaped knee includes all those who have a natural "lower" leg alignment or an "X" shaped leg alignment.

The shoes described herein represent the right shoe to which the present invention is applied, and the present invention applies equally to the left shoe.

Figure 4a is a back view of a person's shoes having the symptoms of degenerative arthritis in the knee in the first embodiment according to the present invention and the main pain in the knee or being transformed into an "O" shaped knee.

As shown in Figure 4a, the shoe sole 140 has a longitudinal cross-sectional structure is configured in a parallelogram shape.

The shoes 100 and 200 include uppers 120 and 220 surrounding the toes and shoe soles 140 and 240 supporting the feet. The shoe soles 140 and 240 have a parallelogram shape in longitudinal cross-section. It is made to be as inclined as possible, and is worn differently according to the site of degenerative knee osteoarthritis and the type of lower extremity skeletal alignment.

(First embodiment)

As shown in FIG. 4A, the shoe sole 140 has an inclination angle of α value toward the outside 180 with respect to the shoe inner 170 vertical line. At this time, the shoe sole 140 is coupled to the upper 120 so that the upper and lower surfaces are horizontal.

Since the shoe sole 140 has an inclination angle α formed at the outer side 180, the center of the sole and the center of the sole of the shoe are shifted. That is, since the center of the sole is located inward from the center of the shoe sole 140, the joint gap between the inner side of the knee is opened by the occurrence of the right moment (moment), thereby reducing the load and narrowing the gap between the left and right knees, while the knee is inward. It is corrected.

At this time, since the shoe sole 140 is in contact with the ground 160 horizontally, the sole is also level with the ground 160 so that no shear force is generated so that the load concentrated on the inner side of the knee is reduced and distributed to the entire knee. When a person has symptoms of degenerative arthritis or is congenital or acquired in the form of an "O" shaped knee, the degenerative knee arthritis pain is alleviated and stable walking is possible.

In addition, even in people with no symptoms of degenerative knee arthritis or those with mild lower limb alignment, the pressure is concentrated to the inside of the knee, so that the shoe 100 having the parallelogram-shaped shoe sole 140 is continuously maintained. Wearing can prevent the development of degenerative knee arthritis. At this time, the shoe sole 140 worn by a person having a normal lower limb skeletal alignment is configured to be smaller than the inclination angle (α) applied to a person having an "O" shaped knee.

In addition, although the symptoms of degenerative knee arthritis did not appear, even if a person with an "O" -shaped knee, the legs 100 in the normal "|" shape when the shoes 100 continuously configured with parallelogram-shaped shoe soles 140 are continuously worn Correction can prevent the development of degenerative knee arthritis.

FIG. 4B is a rear view of the shoe with a shoe attached to the shoe of FIG. 4A. FIG. As shown in FIG. 4B, the wedge-shaped member 142 may be configured to further incline the foot toward the inner side 170 of the insole or the sole 140 of the shoe 100.

If the symptoms of knee arthritis is severe or the deformation of the "O" shaped knee alignment is large, the parallelogram shoe sole 140 and the orthopedic field of the present invention are designed to reduce the load applied to the inner side of the knee and increase the knee correction effect. In the shoe soles or insoles traditionally used in the wedge-shaped member 142 can be further used in combination.

Figure 5a is a back view of a person's shoes having a symptom of degenerative arthritis in the knee in the first embodiment according to the present invention and having a major pain on the outside of the knee or being transformed into an "X" shaped knee. As shown in FIG. 5A, the shoe sole 240 has an inclination angle of α value toward the inner side 270 with respect to the vertical line of the shoe outer side 280. At this time, the shoe sole 240 is coupled to the upper 220 so that the upper and lower surfaces are horizontal.

Since the shoe sole 240 has an inclination angle α formed at the inner side 270, the center of the sole of the shoe is shifted from the center of the shoe bottom. That is, since the center of the sole is located outside the center of the shoe sole 240, the joint gap on the outside of the knee is opened by the occurrence of the right force (moment), thereby reducing the load and widening the gap between the left and right knees, while the knee is outward. It is corrected.

At this time, since the shoe sole 240 is in contact with the ground 260 horizontally, the sole is also level with the ground 260 so that no shear force is generated, thereby reducing the load concentrated on the outside of the knee and dispersing the entire knee outside the knee. When a person has symptoms of degenerative arthritis, or is congenital or acquired in the form of an "X" shaped knee, complex degenerative knee arthritis pain can be alleviated and stable gait can be achieved.

In addition, although the symptoms of degenerative knee arthritis did not appear, even if a person with an "X" -shaped knee, the legs 200 in the normal "|" shape are continuously worn when the shoes 200 composed of parallelogram-shaped shoe soles 240 are continuously worn. Correction can prevent the development of degenerative knee arthritis.

FIG. 5B is a rear view of a shoe in which wedges are added to the shoe of FIG. 5A. FIG. As shown in FIG. 5B, the wedge-shaped member 242 may be configured to further incline the foot toward the outer side 280 of the insole or the sole of the shoe 240 inside the shoe 200.

If the symptoms of knee arthritis is severe or the deformation of the "X" shaped knee alignment is large, the parallelogram shoe sole 240 and the orthopedic shoe of the present invention are designed to reduce the load on the outside of the knee and increase the knee correction effect. The wedge-shaped member 242 may be further combined with a shoe sole or insole traditionally used in the field.

In the case of shoes worn by people with "O" -shaped knees or "X" -shaped knees, the beta value of the angle between the bending axis 70 of the thigh and the mechanical axis 50 is about the soles 140 and 240 of the shoe. It is the same as the inclination angle α inclined to the side.

In addition, since the shape of the leg and the degree of knee bending is not the same for each person, the angle β between the flexion axis 70 and the mechanical axis 50 of the femur connecting the center of the femoral head and the knee joint is also not the same. Therefore, the angle between the flexion axis 70 and the mechanical axis 50 of the femur is determined using X-ray imaging, and the shoe soles 140 and 240 are inclined at the same inclination angle as the angle.

In addition, the shoe sole 140 may be integrally formed, or may be formed by adjusting the inclination angle α by inserting or removing the implant therein.

In addition, it is preferable that the inclination angle α of the shoe sole 140 does not exceed 15 °, and the angle (eg, α is 3 °, 5 °, 7 °, 10 °, 15) according to the severity of arthritis symptoms. If the product is manufactured and sold in advance, the user can select and wear shoes according to his arthritis symptoms and clinical acceptability of the human body.
