--The 4 ligaments of the knee are the ACL, LCL, MCL, and PCL. The Anterior cruciate ligament is located in the center of the knee. This ligament controls rotation and forward movement. Lateral collateral ligament is located on the outside side of the knee, giving stability to the outer knee. Medial collateral ligament is located on the inside of the knee, giving stability to the inner knee. Posterior cruciate ligament is located in the center of the knee, and controls backward movement of the tibia.…
This article is explaining how bad ACL tears truly are and why they are difficult to heal. An acl cannot heal itself, thus making it difficult to try and heal it. Many times when someone tears their ACL, their MCL is also torn. But the ACL does not reknit itself after an injury while the MCL does. Harvard Medical School doctors researched on a better way to heal an acl tear and they learned that using blood clots is a good method. When an MCL is torn, blood clots are created automatically which will help heal the tissue, but this does not happen in ACLs. So these doctors tried to repair ACLs by doing the blood clot scaffolding. They tested these methods on pigs and it was successful. It took about twelve months for the pigs to be as…
The Anterior Cruciate Ligament (ACL) is one of the two cruciate ligaments of the knee, the other being the Posterior Cruciate Ligament (PCL). These ligaments are the stabilizers of the knee. The ACL is a strip of fiber tissue, which is located deep inside the knee joint. It runs from the posterior side of the femur (thigh bone) to the anterior side of the tibia (shin bone) deep inside of the knee. The ligament is a broad, thick cord the size of a person 's index finger. It has long collagen strands woven together in a fashion that permits forces of up to 500 pounds to be exerted. The function of the ACL is to prevent the tibia from moving in front of the knee and femur. The ACL also prevents hyperextension (or extreme stretching of the knee backward) and helps to prevent rotation of the tibia.…
Now this surgery is a very difficult and long process operation. Because there are three ligaments ruptured you have options on how they can be repaired. For the ACL, your options for the graft are the patellar tendon autograft, hamstring tendon autograft, quadriceps tendon autograft, and allografts. The reason these options are considered is because in the past doctors used to just sew the ACL back together, but didn’t have a high recovery rate. For the meniscus you have three options. Meniscectomy, which is the removal of the torn section of the meniscus, a suture repair of the torn section, or an implantation of a cadaver meniscus. The MCL is very unique, unless it is a very severe tear, the MCL will heal on its own once the torn ligaments are repaired. The knee will once again be stabilized after surgery and the MCL will begin to heal. This surgery is arthroscopic meaning that it is done using a small camera inserted into your joint area with a picture being presented on a screen to help surgeons see. The most crucial damage of the ligaments is the ACL and does require reconstructive…
One of the most common knee injuries is an ACL tear and each year 100 000 ACL reconstructions are needed in the United States (10). Current ACL reconstruction options include using either an autograft, which is a graft from another part of the patient’s body, or an allograft, which is a graft from a cadaver. Both of these options have their disadvantages; the biggest one being it takes approximately a year to recover from surgery. When I was in grade 11, I tore my ACL and this prevented me from getting a soccer scholarship to the US because I was unable to compete in the showcase tournaments that were taking place a few months later. Because of this long recovery time, there is a need for a stronger ACL repair that will allow patients to return…

Strength training is the first step from preventing an ACL tear from happening. Proper conditioning and stretching can help as well. Coaches who are very informed can benefit their team from becoming safer players on and off the field. Many speed and balance training programs find ways to reduce injury. Leg muscle strength, core training, and proper footwear with orthotics can suppress the amount of traction in athletic shoes. This helps to minimize friction to avoid injury yet enhances transitional friction to allow peak performance in activities such as cutting and stopping (Westin,…
Though classically related to very long-distance working, any activity that places vital stresses on the front from the knee joint ("patellofemoral") can outcome "runner's knee". This contains repetitive jumping sports activities like basketball or volleyball, as well as skiing, cycling, and soccer. The repetitive pressure and stress between the femur and patella in these…
ACL injuries obtain a detrimental reputation regarding young athletes. Injuries concerning ACL ligament is common amongst high school athletes. However young female athlete’s unfortunate suffer from ACL injuries more frequently than male counterparts. In result of research, muscle diagram of a female may be the cause of ACL injuries. Without bias intent it is noticeable that men are physically stronger yet more muscular than women. Furthermore, ACL injuries perhaps are linked to lack of muscle surrounding the ligament for maximum stability as well as support. According to Gregory D. Myer author of “The effects of gender on quadriceps muscle activation strategies during a maneuver that mimics a high ACL injury risk position” claims, ” Muscle…

A few hours later when I went to the hospital, I discovered that I had torn my Anterior Cruciate Ligament (ACL). Initially, I did not know what to expect from the situation, but I came to realize how much it would affect my life. The ACL functions as a ligament that connects the tibia and the femur. It provides stability in the knee, and with this injury, I could not participate in competitive soccer for 10 months. To undergo this painful experience at such a young age is extremely difficult; however, I chose to embrace the situation rather than let it destroy me. I could no longer play the sport I loved, but I could not change anything about that; I could only control my attitude in this predicament. I went above and beyond at every physical therapy appointment, no matter how strenuous/painful the workouts were. Times frequently came…
One hazard to soccer players is a risk of a torn anterior cruciate ligament, also called the ACL. The ACL is a ligament that connects the thigh bone to the shin bone. A tear of the ACL is caused by the sudden twisting or jerking motion, like the action of a soccer player sliding…
