Description

[0001] APPARATUS FOR CURING DEGENERATIVE ARTHRITIS KNEE [0002]

The present invention relates to a knee orthodontic apparatus for treating degenerative knee arthritis, and more particularly, to a knee orthodontic apparatus for treating degenerative knee arthritis, and more particularly, to a method for alleviating arthritic symptoms including knee pain caused by degenerative knee arthritis, The present invention relates to a knee correcting apparatus capable of correcting a knee.

In general, degenerative knee arthritis is a disease in which the cartilage of the knee joint is deformed and worn out naturally as it gets older, and it becomes painful and difficult to walk. As a result of the trauma of the knee before the aging of the elderly, If you have dislocated joints, obesity, infection, or inflammatory arthritis (such as rheumatoid arthritis), you will have secondary arthritis, and you will not be able to walk with chronic pain.

In the early stages, most of the symptoms are mild, and pain can be controlled with medications such as rest and relief, hot firming, and analgesic anti-inflammatories. When severe edema or pain is severe, occasionally steroids (so-called bone injections) Although these treatments do not restore the disease itself, these conservative therapies consider surgical treatment when the pain is not controlled. The surgical methods include arthroscopic removal of joints and simple resection. But it is known that there is no other alternative to artificial arthroplasty in the event of severe degenerative changes and severe pain.

In particular, degenerative knee arthritis may be accompanied by knee displacements because the cartilage of the knee is worn out and the knee joint is not balanced. The knee joint is a joint located between the lower end of the femur and the upper part of the tibia and the back of the patella and between the bones of the three parts and can be used for the treatment of rickets, osteomalacia, cartilage growth disorder, endocrine abnormality, flexion posture, The knee is bent inward due to various causes of the knee, and the gap between the knees is widened.

More specifically, a knee joint is formed by a hinge joint in which a patella is attached to the inside and the outside of the lower femur and the inside and the outside of the upper end of the tibia, It is a castle dismisses joint with flexion and extension of the knee. It is a hinge joint between the medial condyle and the tibia and between the lateral condyle and the tibia. And a plane joint between the femur. The knee joint is surrounded by synovial fluid filled with synovial fluid, which absorbs friction from the impact and protects the joints.

The tibio-femoral angle appears at the knee joint. The angle between the long axis of the femur and the long axis of the tibia is 185 to 195 degrees from the medial side of the knee, so that the long axis of the femur is greater than the long axis of the tibia It is ~ 10 degrees out. This is called the physiological valgus. The shape of the tibiofemal angle smaller than the normal valgus angle is called the genu varus. In this case, compression occurs inside the knee joint.

As described above, degenerative knee arthritis is accompanied by varus knuckles, knee cartilage is worn out, and the bones abut each other, so that the pain can not be walked. Therefore, it is necessary to develop a technique for relieving and correcting symptoms such as knee pain and pain caused by degenerative knee arthritis.

As a conventional technique related to such a knee correction or traction device for degenerative knee arthritis, Japanese Unexamined Patent Application Publication No. 10-2006-0069539 (Jun. 2006) discloses a technique for relieving pain caused by arthritic knee osteoarthritis, More particularly, the present invention relates to an auxiliary device for preventing osteoarthritis of the knee joint, which is worn by a knee joint degenerative arthritis patient who is deformed into O type (varus knuckle) due to abrasion of articular cartilage, (Knee flexion) and supporting the inner side of the leg in close contact with the auxiliary device to transfer the load from the knee joint to the orthosis to alleviate the pain of the joint, to provide stability of the knee joint and to prevent degenerative arthritis And Patent Application Publication No. 10-2010-0097890 (Sep. 6, 2010) relates to a cold and pressure-applied knee orthosis, more specifically, And a pressure pad having a cold pad which surrounds the knee and radiates cold or heat to the inside of the knee joint.

The above-mentioned Patent Documents 10-2006-0069539 and 10-2010-0097890 disclose a technique of applying a force to the knee joint from the outside to the inside to calibrate the knee joint caused by degenerative knee arthritis, There is a limit to relieve symptoms such as pain and edema that occur when the bones come into contact with the knee joint by stretching the joint area.

In addition, as a technique relating to a device capable of tensioning a knee joint region, in Patent Publication 10-0648639 (Nov. 23, 2006) and No. 10-0814427 (Mar. 18, 2008) The space between the femur and the cartilage of the knee joint is widened by the structural features of the knee joint so that the cartilage of the knee joint is worn or damaged, and the wearer suffering from the severe pain and impact experienced by the wearer remarkably alleviates pain in the knee arthritis A description of a device that can be used in the present invention is described.
