Essay On Knee Joint

With the rising popularity of sports; hockey, football, and, skiing, the Medial Cruciate Ligament of the knee, is the top-rated injury of the ligaments in the knee. It doesn’t necessarily have to include sports, but rather focuses on the valgus stress or force to the knee. A valgus force is blow with a severe force to the lateral portion of the knee, and is paired with the term sprain. The MCL constricts abduction of the knee, and constricts external rotation of the tibia on the femur. With this, the medical cruciate ligament functions to stabilize the knee against lateral or valgus forces.

Therefore, synovial fluid found in the joint helps minimize friction during extension and flexion of the knee because the viscous fluid functions as a lubricant to act as an absorber to prevent bones from hitting one another. Also, hyaline cartilage helps minimize friction by providing a smooth sliding area that still allows minimum movement of bone without hitting one another.

In the United States there is between 100,000 and 200,000 ACL tears a year (anterior). This number may be more but due to the limited data since if you do tear your ACL you do not have to register nothing so if you don't register that you tore your ACL then the number does not go up. Most ACL injuries come from non contact sports or athletics. Surgery is highly recommended for ACL tears. ACL tears can affect lots of people but with surgery you can come back from an injury better than before.

If you have a torn meniscus, which is a ligament in your knee, then you may think that your only option is to undergo invasive surgery so you can be active again and free from pain, . However, a study conducted by Harvard Medical School determined that physical therapy works just as well as surgery to repair a torn meniscus. Read on to find out just how physical therapy can lead to comparable results when treating this condition and examples of what therapy will involve.

collateral ligaments, there are two of these, one on the outside of the knee called lateral collateral ligament (LCL), and the medial or "inside" collateral ligament (MCL). These injuries are from being hit or pushed directly to either side of the knee which will cause a sprain to which ever side has been hit.

All of us like staying healthy and fit but it can be disturbing when pain checks in, more especially hip pain; this inevitably calls for attention in so many ways.

What is the medial collateral ligament (MCL)? The MCL is one of the main four ligaments that is part of the knee. This ligament is a broad, thick band that runs down the inner part of the knee, from the femur to the top of the tibia, but is located outside the joint itself. The job of the MCL is to support the knee with the help of the other ligaments in the knee. When stress is applied to this ligament it aids control in transferring the join through a normal range of motion. Also, the MCL prevents an anterior movement of the tibia and hyperextension. Other roles of the MCL include joint proprioception, when stretched beyond limits. The MCL is understood as being the most common ligament injury of the knee. While the MCL plays an important

The aim of this review paper is to access the anterior cruciate ligament (ACL) injury of the knee (tibiofemoral) joint, which is a common sport and exercise injury related to the musculoskeletal system. Investigation of the anatomy and physiology of the knee joint, and the diagnosis, etiology, pathophysiology, treatment, rehabilitation and prevention of ACL injuries will provide a descriptive epidemiology. This will aid readers in making informed management and treatment decisions, and guide them to safely perform movements to prevent injury. This review paper will incorporate holistic views on relevant scientific research, including primary resources such as journal articles and lecture notes, which will be cross-referenced

The cartilage can be damaged or worn by previous injury such as an elbow dislocation or fracture. Another reason for this injury to occur would be the deterioration of the joint cartilage due to aging. This injury typically affects the weight bearing joints. However osteoarthritis least affects the elbow joint because of its well matched joint surfaces, strong stabilizing ligaments and it can tolerate large forces without becoming unstable.

Together with the posterior cruciate ligament, which crosses over it to form an X, the ACL helps keep the knee stable while rotating. The ACL keeps the shinbone in place and prevents it from moving too far forward and away from the knee and thighbone. It also provides stability when rotating the shinbone(Anterior Cruciate Ligament (ACL) Injuries.).

The ACL crosses diagonally in the middle of the knee behind the patella and it connects the tibia to the femur. Its function is to prevent the tibia from sliding in front of the femur and to prevent overextension of the knee. The LCL connects the femur to the fibula and its function is to keep the lateral side of the knee stable. RG3’s injury is due to an ACL and LCL tear. The ACL was torn when his foot planted in the field and his knee cut into internal rotation. His LCL was torn due to excessive knee adduction. He was susceptible to this turn of events due to a prior injury caused by landing wrong after a jump. When he performed the long jump his knees internally rotated past their range of motion.

The story is all too common, a young athlete with lots of promise, and then it all come crashing down. The culprit? A torn ACL. ACL stands for Anterior Cruciate Ligament (McDaniel). “The ACL is one of the four major ligaments that works to stabilize and support the knee. The ACL is “behind the patella and connects the Femur to the tibia,” (McDaniel). It prevents the tibia from moving too far forward on the femur and it limits the rotational movement of the knee,”(“Why do Females”). Basically the ACL is a stabilizer of the knee (McDaniel). An ACL injury happens when the ligament has been overstretched or when when it is torn. The risk of tearing a ACL as a teen is extremely high especially for girls. The common age for girls to tear their ACL

This is a 63-year-old male with a 10/06/1978 date of injury. He fell between two walls and injured his left knee.

Projections at CJJT differ from other sites. If you do not have a total knee replacement, the projection they do is a “four view knee” which is an AP/PA, PA tunnel view, lateral, and sunrise. If you do have a total or a partial knee replacement, they do a “three view knee” which is an AP/PA, lateral, and sunrise. A 65-year-old female came into the clinic in a wheelchair and could hardly stand on either leg. She stated she had a left total knee replacement and still couldn’t bare to stand on it. The physician wanted to take a look at both knees and since she had one total knee replacement and nothing done to the other knee the physician ordered a bilateral PA, tunnel and sunrise knees with additional images of a lateral on each knee. Once I was done taking those images, I went and got the technologist, Lori Huffman (who is also the CI) who approved my images.
