The role of the anterior cruciate ligament 30, the role of the anterior cruciate ligament

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 joint moves, a portion of the fibers in each of the two ligaments is in a state of 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!

The anterior cruciate ligament and the posterior cruciate ligament of the knee joint are familiar to everyone, they play a key role in the stability of the knee joint, the anterior fork prevents the tibia from moving forward and rotating relative to the femur, and the posterior fork prevents the femur from sliding forward.

It is used to fight Zhengdeng.

How long does it take to heal: The cruciate ligament of the knee is generally longer, and it usually takes more than half a year. Normal running for around 90 days should be fine. Remember to follow your doctor's instructions to endure pain.

Is it the same after healing: Unfortunately, it can't be exactly the same, and you usually recover to 90% and above, but if you're not a professional athlete, that doesn't affect you.

I had a reconstructed ankle ligament and the recovery went quite well.

Be sure to follow your doctor's instructions for proper recovery training

What are the main functions of the fork ligament?

Correct Answer: Maintain the stability of the western joint, the anterior cruciate ligament prevents the tibia from moving anteriorly, and the posterior cruciate ligament prevents the tibial branch from moving backward and allowing the hitch to move early.

1. First of all, let me tell you whether the anterior fork ligament is ruptured, and a good doctor can confirm the diagnosis by physical examination combined with MRI, and you don't need to see it first. It can be determined before surgery. The doctor said that it was very unprofessional to observe this first, and it was recommended to change hospitals, preferably in the sports injury department.

If it is determined that the degree of anterior fork rupture, surgery is recommended, the ligament will not rise on its own, the pressure on the meniscus is greater if the ligament is broken, and the knee joint is relatively loose and easy to be injured! If you have surgery, you can also repair your meniscus, because the injured part of your meniscus is a non-blood supply area, and it cannot heal by yourself.

2. It must be that the recovery of autologous is better, and the postoperative autologous ** is relatively easy, the issue of life does not need to be considered, both autologous and allogeneic can be used permanently, and now the technology is very good, don't worry. In addition, allogeneic will not be rejected, rejection refers to the exclusionary reaction caused by organ transplantation, and allogeneic ligaments belong to tissue transplantation and will not have an exclusive reaction. There is no cost for autologous, and the allogeneic medical insurance is not reimbursed, and the allogeneic ** in Beijing is about 9000 for reference.

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 **.

Hello. Regarding these two issues, the anterior drawer test has a mobility of 6 mm, indicating that the anterior cruciate ligament has been damaged, and it should not have been completely ruptured at that time, so after such a long period of repair, Sissen still has a certain amount of relaxation, but on magnetic resonance, because the original damaged site has been filled by synovial membrane or fibrous tissue, it is difficult to distinguish on magnetic resonance.

The movement of 6mm can be considered without surgery, because if the mobility is purely used to judge whether surgery should be performed, then the anterior drawer test should be more than 2+, that is, the movement is more than 10mm, which is a clear indication that the anterior cruciate ligament needs to be surgically reconstructed, 6mm can be conservative, but if the joint is usually obviously uncomfortable, especially accompanied by meniscus injury, then surgical reconstruction, and more importantly, repair the meniscus at the same time, is also a good choice, because meniscus injury is difficult to repair on its own, Therefore, early treatment of the meniscus should be a must.

It is also important to note that if you are now doing the pre-examination drawer test without a pure hood under anesthesia, if it is now 6mm, then the examination under anaesthesia (EUA) may increase the anterior drawer test significantly by more than 10mm, and this is the most accurate time.

Therefore, considering your cruciate ligament and meniscus, as well as your age, I would prefer surgery to stabilize your joints, which should be the best policy.

I don't understand what you said too much, but the principle of handling it should be the same, for reference.

Good bye. Dr. Pan Haile of the Second Hospital of Harbin Medical University solemnly reminded that because the patient cannot be seen face-to-face and cannot fully understand the condition, the above suggestions are for reference only, and the specific diagnosis and treatment must be carried out in the hospital under the guidance of the doctor! )

Cruciate ligament injuries are like torn cloths, they cannot be broken neatly, they are tears between the fibers. In the early stage of the injury, bleeding and swelling will be found on MRI, but if the MRI scan is not in the right position, it may not be found.

Diagnosis is by physical examination, and anterior cruciate ligament injury is more likely if the anterior drawer test is laxity compared to the contralateral side. If the ACL is damaged, it can lead to instability of the joint, which can lead to joint wear and tear and premature osteoarthropathy, so if the joint is damaged and unstable, the ACL needs to be reconstructed.
