Detailed description for carrying out the knee protector according to the present invention will be described with reference to the drawings.

The skeleton and structure around the knee are as shown in Figs. Femur (B1) is a so-called femur, a long bone that connects between the hip joint below the pelvis, and the tibia (B2) refers to the inner bone of the bone forming the calf as a tibia. The main skeleton is organically connected with the patella (B3), cartilage (B4), anterior cruciate ligament (B5) and posterior cruciate ligament (B6).

Patella (B3) is a so-called knee bone dish-shaped bone in front of the knee joint triangular chestnut-shaped bone is relatively flat bone. It is contained in the tendon of the quadriceps muscle (大腿 四 頭 筋). Together with the patella of the femur, it forms a joint and moves well according to the flexion movement of the knee.

Cartilage (B4) is a tissue consisting of chondrocytes and cartilage substrate. If relatively little movement is required, the cartilage joint forms between the bone and the bone, and if much movement is required, the lubricating joint is placed in contact with the lubricant between the cartilage surfaces. The cartilage has high elasticity, cushioning against a given force, and the friction coefficient of the articular cartilage is very low, which helps the joint move in almost no friction.

The anterior cruciate ligament (B5) is the primary stabilizing structure for the anterior movement of the knee and ruptures due to torsion or wetting beyond the ligament's force. Prevents forward movement of the tibia and excessive extension and limits the internal rotation of the tibia. There is also partial rupture, but often complete rupture by non-contact damage. It is also accompanied by meniscus tears.

The posterior cruciate ligament (B6) is a very important ligament so that it does not move backward with respect to the femur (B1) and tibia (B2). The medial femur (B1) is attached to the posterior side of the tibia (B2), starting between the articular ridges and traveling in an oblique direction. It is the strongest of the knee ligaments that prevents posterior dislocation and overextension, but in rare cases alone damage occurs. The extent of the damage is manifested as stretching damage or complete rupture. It is less common than anterior cruciate ligament injury and is often neglected.

The knee protector according to the present invention protects the main part constituting the knee, and provides a structure that can effectively support and compress to recover the damaged part quickly, so as to properly respond to various external environments encountered in everyday life We propose an effective structure that allows proper joint movement even when the knee guard is worn. Hereinafter, the structure will be described in detail with reference to the drawings.
