Where is the posterior cruciate ligament and is the posterior cruciate ligament broken?

Inside the knee joint, connect the thigh and the calf, the calf connection point is in the calf protrusion, and the thigh connection point is at the back.

Hehe, to tell you the truth, no matter where the plaster is applied, it cannot penetrate there, because it is connected between the thigh bone and the calf bone;

If the injury of the posterior cruciate ligament is severe, the main way is surgery, if the rupture is not serious, you need to wear a plaster cast, and it is definitely not a plaster.

First of all, I wish you a speedy **.

Posterior cruciate ligament injury is not necessarily a rupture, but may also be a strain or contusion caused by an external force on the knee joint.

If it is only a simple ligament injury, it is mainly to take conservative**, avoid the movement of the knee joint, bed rest can be given braces and other fixations to promote the repair of ligaments, reduce swelling and pain, in addition, local acupuncture and physiotherapy can be given.

If the swelling and pain are more obvious, you can also take some oral drugs to invigorate blood and relieve pain, and after the injury is repaired, you can gradually carry out active and passive flexion and extension exercises of the knee joint. If the ligament is ruptured, the function of the knee joint is often affected, and in severe cases, it may also cause traumatic arthritis, and surgery should be taken in time to reconstruct the ligament and promote the recovery of knee joint function.

First of all, I will introduce you to the tibia, femur and cruciate ligament, the surface of the tibia is not flat, but like the word "concave", the two sides protrude and the middle is concave, and the upper femur is like the inverted "convex" word, low on both sides, high in the middle, and the tibial plane fits each other, and the anterior cruciate ligament and the posterior cruciate ligament together form the cruciate ligament of the knee joint.

Taking the right leg as an example, the anterior cruciate ligament is naturally in front, and his lower end is connected to the medial surface of the right tibia, that is, the left side of the word "concave", and the upper end is connected to the protrusion of the right femur, while the posterior cruciate ligament is behind the anterior cruciate ligament, and his lower end is connected to the lateral aspect of the right tibia necklace, and the upper end is connected to the front of the femoral protrusion, but below the anterior cruciate ligament. The cruciate ligament is an important ligament that holds the knee joint, it is related to the stability of the knee joint, and if there is an injury (such as a tear) then the movement of the knee joint will be affected. The structure on the left side is mirror-related to the right knee.

Knee cruciate ligament: an important stabilizing structure of the knee joint, which is hinged between the femoral intercondylar fossa and the intercondylar bulge of the tibia, which prevents the tibia from moving anteriorly and posteriorly along the femur. The anterior cruciate ligament originates from the medial surface of the lateral femoral condyle, obliquely anterior and inferiorly, and ends at the anterior part of the intercondyle tibial bulge and the anterior horn of the medial and lateral meniscus; The posterior cruciate ligament arises from the lateral aspect of the medial femoral condyle, obliquely posterior and inferiorly, and terminates at the posterior angle of the lateral meniscus of the intercondyle of the tibia.

When the knee is moved.

, a portion of the fibers in each of the two ligaments is under tension. Thus, in addition to the anterior cruciate ligament preventing anterior displacement of the tibia and the posterior cruciate ligament preventing posterior displacement of the leg bone, it can also limit hyperextension, hyperflexion, and rotational movement of the knee joint, and cruciate ligament injuries often occur at the same time as tibial collateral ligament or meniscus injuries.

Due to the general lack of understanding of ACL injuries and the fact that the injury does not affect daily life, a large number of ACL injuries are in the general population! If the cruciate ligament injury is not ** for more than 3 months, the meniscus injury is almost inevitable, followed by irreversible diseases such as articular cartilage damage and joint degeneration. Expert Reminder:

If you feel like you can't stop or turn sharply on a fast walk, you should see a sports medicine doctor to determine if you have an ACL injury!
