What is a quadruple tendon?
The four -headed muscle tendon is a common tendon of four quadriceps femoris muscles in the thigh. It is located where these four muscles are closer to the bottom of the front of the thigh, just above the knee, and attach to the patella or vaults. Although it is a tendon and not muscles, this fibrous stripe plays an important role in bending and extending or bending and straightening the knee. This tendon then continues again and around Kneecap to form a patellar ligament just below it, a structure that connects the patella with the bone of the tibia in the lower leg. As such, it is difficult to define exactly where the tendon ends, but because it intersects the knee and connects the bones of the femur in the thigh with the tibia, any move developed on the quadriceps of the tendon from the contraction of the quadriceps excluded the elongation of the knee joint.
Like all tendons, the quadriceps tendon consists of tightly tied collagen fibers. Although cannot achieve a change in length, which is able to achieve its neighboring muscle groups, this tendon can be considered spring. Not only can it transmit the forces from the four -headed muscle muscles through the knee joint and help stabilize the knee, but it can store the elastic energy formed until it is ready to relax. For example, when a person puts his leg on the staircase in preparation to take a step, quadriceps and their tendons are stretched when the knee is bent. After pushing up and straightening the leg, the quadruple -headed contract and the stored energy in the tendon are liberated, allowing greater generation of strength in the muscles.
Because the muscles of quadriceps and quadriceps tendons are so often activated during activity - running, jumping, climbing and undercutting everything depends strongly on quadriceps to extend the legs - they are also commonly injured, especially if they are weak or inflexible. Typical tendon injuries include tension, partial tears and complete tears. Trunks occur when the tissue is overloaded and most often occur whereThe muscles converge at the tendon. Tears most often affect the base of the muscle rectus femoris, the furthest of the four four -headed muscle muscles. In addition, there is common tendonitis here, which is the result of repeated wear on tendons from frequent running, jumping or other similar activities.
