Knee Correction Device For Treating Degenerative Knee Arthritis

The present invention relates to a knee correction apparatus for the treatment of degenerative knee arthritis, and more particularly to alleviate the symptoms of arthritis including knee pain due to degenerative knee arthritis, and also to the limbs such as the inner leg (O-shaped leg) due to degenerative knee arthritis. It relates to a knee correction device that can correct.

In general, degenerative knee arthritis is a disease in which the cartilage of the knee joint degenerates and wears down with age, causing pain and difficulty in walking. If there is dislocation of the joint, obesity, infection, or inflammatory arthritis (such as rheumatoid arthritis) for a long time, secondary arthritis progresses, and cartilage disappears, and when bones come into contact with each other, it is impossible to walk with continuous pain.

In the early stages, most of the symptoms are mild, so it is possible to control the pain with medications such as rest and stability, hot compresses, and analgesic anti-inflammatory drugs.In case of severe swelling or pain, sometimes steroids (so-called bone injections) are injected into the joints for temporary symptoms. Although this may not alleviate the disease itself, such conservative therapy may consider surgical treatment when the pain is not controlled. Surgical methods include arthroscopic cleaning of the joint and simple resection. Although it can be effective only early, degenerative changes are significantly progressing and pain is known that there is no other alternative than artificial joint replacement.

In particular, degenerative knee arthritis wears down the cartilage of the knee joint, preventing the knee joint from equilibrium. The knee joint is a joint between the lower part of the femur, the upper part of the tibia and the back of the patella, and the bone of the subdivided bone, rickets, osteomalacia, cartilage growth disorder, endocrine dysfunction, bent posture, unbalanced, malnutrition, lack of exercise, degenerative arthritis, etc. The knee joint is bent inwardly due to various causes of the knee joint, the gap between the knees is earned, also known as inner varnish.

More specifically, the knee joint is where the inner and outer sides of the femur and the inner and outer sides of the tibia are in contact with each other to form a hinge joint with a patella attached to the front. Castle dismisses joint, knee flexion and extension, hinge joint between medial condyle and tibia and between lateral condyle and tibia, patella It consists of a plane joint between the femur and the femur. The knee joint is surrounded by a synovial sac filled with synovial fluid, which absorbs friction from shock and protects the joint.

In the knee joint, the tibio-femoral angle appears, which is the angle where the long axis of the tibia meets perpendicular to the long axis of the femur. The femoral axis is 185 degrees to 195 degrees in the inner side of the knee. ~ 10 degrees off This is called physiological valgus, and the shape of the femoral tibia smaller than the normal valgus is called the varus (genu varus). In this case, compression occurs inside the knee joint.

As described above, the degenerative knee arthritis accompanies the varus, and the knee cartilage is worn down, and the bones come into contact with each other, so that the pain cannot be walked. In accordance with such circumstances, there is a need for a technology development for a device that can alleviate and correct symptoms such as varus and pain caused by degenerative knee arthritis.
