Description

MULTI-ANGLE KNEE JOINT TRACTION APPARATUS}

The present invention relates to a multi-angle knee traction treatment device.

In general, a disease that causes a disorder of the knee joint structure may include arthritis, and the knee joint structure may be deformed due to exercise damage.

In addition, examples of knee joint deformation include the varus (O-shaped leg) and the valgus (X-shaped leg).

Arthritis is a disease in which inflammation and pain occur in the joint, and it can be mainly divided into osteoarthritis (degenerative arthritis) and rheumatoid arthritis.

Osteoarthritis, also called degenerative arthritis, occurs mainly in old age without a particular organic cause, and when chronically progressed, it is accompanied by movement disorders such as gait disorder due to deformation of the joint structure. Osteoarthritis is mainly caused by gradual damage to the cartilage or degenerative changes of the bones and ligaments of the joints, resulting in inflammation and pain.

Rheumatoid arthritis is an inflammatory disease characterized by multiple arthritis, and autoimmunity is known as the main mechanism. In terms of symptoms, inflammation occurs in the synovial membrane tissue, and pain occurs as the joint swells.

As this inflammation persists, inflammatory synovial tissue hyperplasia destroys bones and cartilage, alters joint structure and causes movement disorders.

Both osteoarthritis and rheumatoid arthritis cause changes in the joint structure, such as the destruction of the cartilage joint. In general, the joint gap narrows gradually, and the hardening of the joint cartilage increases. Also, as the arthritis progresses, a bone-like bone is formed at the edge of the joint surface and the joint surface becomes irregular.

Therefore, it is necessary to assist in the treatment of the knee joint so that the deformation of the knee structure can be restored to the normal joint structure without fixation, and can be restored to the normal joint structure by helping the normal movement of the knee joint.

However, conventional knee arthroplasty is a simple joint motion range (ROM) movement, ie, lower leg movement within the knee range, aimed at enhancing joint mobility without consideration of the patient's adherent soft and scar tissue conditions. Only lifting and lowering range of motion is performed.

In addition, when the cartilage parts are stuck together in the situation where the joint movement range movement is impossible after the knee surgery, a great difficulty occurs in rehabilitation exercise. Since the conventional knee treatment aid provides only the joint movement range movement, it does not prevent the cartilage portions from sticking together after the operation. There was a problem.
