--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.…
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…
Objective: To learn the function of the knee and how its ligaments work to create the movement the knee makes by taking apart the knee and reconstructing it with different materials to replace the ligaments.…
The knee can be subjected to multiple injuries such as the disruption of the anterior cruciate ligament (ACL), disruption of the medial collateral ligament (MCL), and a wide range of other injuries. This paper will describe the anatomy of the Posterior cruciate ligament and focus on injuries associated with it. It will also describe the causes of PCL injuries and what kind of examination and treatment of the PCL, as well as ways to avoid this kind of injury. It will also describe the degree of…
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…
Lacrosse is a sport that is becoming more popular around the world. Lacrosse is a fast paced game that requires a lot of movement. In some cases, injury can occur. A common injury that occurs during a lacrosse game is tearing your ACL. ACL stands for anterior cruciate ligament. ACL is one of the four main ligaments you have in your knee. While playing lacrosse, you tend to make very quick movements, which can cause this tear to happen. Without this ligament, your knee will be unstable and surgery is essential. ACL tears in athletes happen far too often. The long recovery process is what motivates athletes to become a better player when they get back on the field.…
The ACL also known as the anterior cruciate ligament is one of the four major ligaments in the knee that allows stability (about.com). ACL tears are most common in athletes and especially in female athletes. There are many ways to tear your ACL, whether it is with contact or no contact. There are also minimal symptoms for an ACL tear but they are very important to look for when an athlete is complaining about knee pain. The treatments for this injury also depend on the severity of the tear. The severity could determine if surgery is needed. These are all important things to know when you are in a situation with a person that has torn their ACL. Tearing your ACL can come at the snap of a finger, and that is what makes it scary for…
The Anterior Cruciate Ligament (ACL) found in the knee connects the femur (thigh bone) to the tibia (shin) and provides stability to the knee. The ACL prevents the tibia from shifting too far forward and from rotating too far inward under the femur. The recent increase of this injury has parents, athletes, doctors, and coaches in fear. Athletes and parents fear the injury to due the expensive surgery, and the difficult physical emotional and mental recovery. The classic tearing of the Anterior Cruciate Ligament has no contact involved and occurs when an athlete is stopping suddenly, cutting, twisting, and jumping. The athlete…
Sports have been around since the olympics in 790 B.C., yet only recently has the affects of these sports on our body been addressed. Dr. Bennet Omalu brought attention to the NFLs injuries like no other in 2002, when he discovered that the former football star Mike Webster, the Pittsburgh Steelers championship center, had a degenerative brain disease due to constant head trauma(1). Since the discovery other sports, such as rodeo for example, have shown that the NFL isn’t the only sport dealing with the effects of concussions(2). I was drawn to this subject because I wanted to learn about a topic that I find interesting and could use in my day to day life.…
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…
The MCL is the ligament on the inside of the knee, giving it support and keeping the knee from collapsing in. Luckily, for me, the MCL…
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…
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…
According to Ellenbecker et al (2009) the reported injury rates for tennis elbow were high ranging from 37-57% in recreational and professional players, most of which are over the age of 30. (3) Prevalence rate of tennis elbow is quite the same for both males and females throughout various studies. Smedt et al (2007) suggested that this injury commonly affects novice players rather than professionals. (4) There are many biomechanical factors which lead to this injury such as age, level of play, experience of player and muscle imbalances. In this essay, however, I will discuss how poor technique and equipment used can cause this type of…
