Essay about The Human Knee

An injury to the ACL is classified as a sprain. A sprain is a joint injury that causes a stretch or a tear in a ligament. Sprains are graded I, II, or III depending on how severe the injury is. A grade I sprain will have pain with minimal damage to the ligaments. A grade II sprain is going to have more ligament damage and mild looseness of the joint. Finally, in a grade III sprain, the ligament is completely torn and the joint is very loose or unstable. A grade III sprain, simply called an ACL tear, is most often a sports-related injury. Still, The ACL can be torn in other instances such as during rough play, vehicular collisions, falls, and work –related injuries. According to a study performed by Jonathan Cluett, M.D., about 80% of sports-related ACL tears are “non-contact” injuries. This means that the injury does not result from any contact with another athlete. A rupture to the ACL is the result of the ligament within the knee being overstretched. This is usually caused by a “plant-pivot” mechanism (a stop and twist motion) of the knee, or a blunt force to the front of the knee. Other factors include quick changes of motion, twisting or torquing, or landing from a jump. Hyperextension is most

This injury is common in athletes who make repeated overhead motions. UCL injuries can range from minor inflammation to a complete ligament tear.

An anterior cruciate ligament tear can be confirmed by the Lachman test, the dynamic extension test, and the Pivot jerk test. The Lachman test and dynamic extension test is helpful in, “making a diagnosis, particularly in the acute injury.” (1) The lateral pivot test reproduces, “the rotatory subluxation that occurs in ACL defiency. The test is difficult to perform and takes residents and fellows in my practice approximately three months of intensive training to be able to adequately perform the jerk test in the unanaesthetised patient.”(1) The test is important because the demonstration of the lateral pivot jerk is the replication of the instability that the patient has. The initial goals of treatment immediately after injury are to reduce pain, reduce

The anterior cruciate ligament (ACL) is one of the four main ligaments in the knee joint that connect it to the shin bone (tibia) and thigh bone (femur). It 's located deep within the joint, behind the kneecap (patella), above the shinbone, and below the thighbone. The ACL lies diagonally across the middle of the knee and plays a role in keeping the knee stable during movement. Partial tears of the ACL can occur, but are rare. Most ACL tears are either near-completes or complete tears. After experiencing an ACL tear, an athlete has a 15 times

An anterior cruciate ligament (ACL) injury is the overstretching or tearing of the in the knee. This muscle is located just below the knee bone and the tear that occurs may be partial or complete. When you hear your ACL pop that’s a clear sign of a tear. Lots of people have surgery to get it repaired. It is about a year recovery of rehab. Many times when you tear your ACL, there’s no

These boots move the forces caused by a fall to the knee rather than the ankle or lower leg. The ACL injury usually occurs when the knee is forcefully twisted, or hyper-extended. Many patients recall hearing a loud pop when the ligament tears, and feel the knee give way. This injury has received a great deal of attention from orthopedic surgeons over the past 15 years and very successful operations to reconstruct the torn anterior cruciate ligament have been performed.

With an ever increasing number of people becoming involved with athletic activities, there is an increasing number of injuries occurring which can be devastating for the individual. Most of the injuries that affect athletes occur in one of four structures in the human body: bones, muscles, tendons, or ligaments. Because ligaments attach bone to bone and play a major part in providing stability for joints, the major stabilizing ligament in the knee, the anterior cruciate ligament (ACL), assists in performing everyday actions of the human body including sitting, standing, walking, running, dancing, and participating in other sports. The injury that specifically affects this ligament is very serious and always

ACL (Anterior Cruciate Ligament) tears relates back to Egyptian era. Back then, they first started by trying to stitch the ACL back together where it tore, that’s how surgeons learned about grafting. Starting off, the hamstring was the first thing they tried using this new technique on. After success with the hamstring graft, they moved to trying the patellar tendon graft, which was also successful. Fortunately, surgeons now have many ways to repair ACL

The Anterior Cruciate Ligament also known as the ACL is deemed the most commonly torn ligament in the knee and can result from both contact and noncontact injuries. Most Anterior Cruciate Ligament injuries result from an extreme force on the lateral side of the person’s knee causing a valgus force which pushes the knee inward (Kisner & Colby, 2012, pp. 802-803). This injury to the side of the knee can also cause a “Terrible Triad” injury which also injures both the medial meniscus and the medial collateral ligament (Kisner & Colby, 2012, p. 803). Our textbook further states that “the most common noncontact mechanism is a rotational mechanism in which the tibia is externally rotated on the planted foot….this mechanism can account for as many as 78% of all ACL injuries” (Kisner & Colby, 2012, p. 803). If the person does not seek medical help with this injury they are susceptible to also injuring the remaining support ligaments as well. Patients usually present with joint effusion; possibly 25 degrees of flexion, joint swelling if blood vessels are involved, limited ROM, stress pain and instability along with quads avoidance gait patterns (Kisner & Colby, 2011, p. 208)

In the sports world the word ACL brings absolute horror and cringe with it. That’s because when an ACL tears it can be one of the most painful experiences an athlete can have, especially with the surgeries and recovery it brings with it. Along with that, the ACL is in the deep part of the middle of the knee, so most of the time when you damage your ACL you most likely have damaged something else. Women especially have to worry about the overall health of their knees as they have a 4.8% greater chance of tearing their ACL than men (Musgrave). ACL tears are one of the worst injuries in the sports world and in order to recover to full health it takes time, patience, and a hard-work ethic.

Overall it is an important ligament in the knee and it is assisted by the muscles surrounding it which helps with stabilization during lower extremity movements. The reality is that sometimes the ACL can’t endure certain movements in the knee and the ligament can be torn (School of Physical Therapy at Texas Woman 's University).

A torn ACL is one of the most serious and common knee injuries. Many aspects play a role in the treatment and rehabilitation of this injury. This paper will discuss the anatomy of the knee, describe a torn ACL, and the rehabilitation.

The knee joint consists of four ligaments, two intra-capsular which are the ACL and the PCL and two extra-capsular ligaments including the MCL and LCL. The ACL is an extremely strong stabiliser which prevents anterior displacement of the knee. The ACL is a ligament and therefore connects one bone to another, the femur with the tibia. The ACLs origin is from the anterior intercondylar eminence of the tibia (home,2017) and the fibres pass upwards, backward and laterally inserting into the lateral condyle of the femur.

Sports is the biggest reason for way these things occur. A tear of any degree, in any part of the knee joint requires at least four to twelve months to heal if it does not require surgery. Now this healing process will more than likely require the person to stay off his feet as much as possible, avoid any physical activities. Also this type of injury will cause the person extreme pain as they constantly be limping, while doing something as basic as walking. This will severely handicap the person not allowing to get anywhere walking fast, not allowing them to participate in the things like. Now this however can get even worse, if the tear is a moderate or severe tear it will require surgery. This will completely and utterly disable the person, forcing them to use either be on crutches or on a wheel chair, and there leg will be in a brace for about six months. When surgery in the knee occurs while it does take six months to recover, it is only to the point at which the person ca effectively walk and that’s about it just walk. The person must go through a grueling process of reteaching his or her leg to run and jump, they work on it until it physically it is on par with the other leg or at the level it was before the injury. Now while all this may happen, something else often occurs, depression. Most of the people with ligament and tendon tears are athletes, when your body is injured you lose the main source of

The ACL is the most common knee ligament to get injured. The ACL injury causes from taking a hard hit on
