The Knee Joint And The Rehabilitation Process

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

Abby describes when athletes typically tear their ACL they are rolling around screaming, unable to walk off. This was not the case for her, however something was wrong so she went to an orthopedic doctor. Due to her stability the doctor did not order an MRI and assumed it was a strained PCL.

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

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.

Each year, approximately a quarter of a million physically active young people experience an anterior cruciate ligament (ACL) injury, and seventy percent of these ACL injuries will be sustained while engaging in non-contact activities such as sudden deceleration while landing (Begalle et al., 2012). This type of injury is grossly detrimental not only on the occasion in which it occurs but also for the subsequent years to come. The majority of individuals who injure their ACL also go on to either, re-injure that same ACL, or injure the opposite knee. Furthermore, our bodies are put in tremendously vulnerable planes of motion during sporting events, especially during activities such as, basketball, football, or soccer. In this day

The ACL is one of the most frequently uinjured ligaments of the knee.( 59 )

The anterior cruciate ligament (ACL) has limited range of motion, which leads to it being the most frequently injured ligament singularly (Ireland, 1999). This study was conducted to present the epidemiology on ACL injuries in female athletes (Ireland, 1999). Epidemiology is the part of science that focuses on the causes, effects, and patterns of disease and health conditions that occur in specific populations. The epidemiology in this article focuses on female athletes that have had a noncontact ACL injury playing either basketball or soccer (Ireland, 1999).

The Anterior Cruciate Ligament (ACL) and the Posterior Cruciate Ligament (PCL) are located inside the knee joint. The ACL and PCL form an ‘X’ behind the kneecap (patella), with the ACL resting in front of the PCL. Both of these ligaments are responsible for controlling the back and forth motion of the knee joint; however, the ACL is responsible for stabilizing the kneecap ). In addition, the ACL is responsible for preventing the shin bone (tibia) from sliding forward on the thigh bone (femur). The ACL provides the knee with stability while an individual pivots or twists. This ligament is critical because without it, performing any kind of rotational activity is impossible, particularly when it comes to playing sports like soccer and basketball.

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

A torn ACL is a injury in which also is a torn anterior cruciate ligament in the knee. When someone tears their ACL they have to have a surgery to replace it. ACL injuries range from mild, such as a small tear, to severe such as when the ligament tears completely or when the ligament and part of the bone separate from the rest of the bone. A lot of the time some of the other knee ligaments or parts of the knee are also injured. This includes cartilage such as the menisci, or bones in the knee joint they also can be broken. Your ACL can be broken during sport activities. During an activity if your leg is planted firmly on the ground then hit by a heavy/large force it could tear the ACL. Some ways your ACL can be tore is by being bent backwards,

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)

When an ACL tears it can be one of the most painful injuries and experiences an athlete can have in their sports career and is one of the worst muscles to be torn. ACL injuries most often occur during sporting events that involve sudden stops, jumping, awkward landings, “out of control play”, and sharp cuts- such as basketball, soccer, football, tennis, downhill skiing, volleyball, lacrosse, and gymnastics. When an injury to the ACL occurs, most people hear or feel a popping sensation in the knee.”I landed with my left knee locked, only to hear something akin to the popping of a paper bag filled with air or the snapping of a large rubber band, a sound so weirdly powerful that I couldn’t believe it was coming from inside my body”, said Mike Swift in his article about ACL tears in the Hartford Courant newspaper, as he describes how it felt when he tore his ACL playing basketball. Along with the popping sensation the knee may also swell, and feel unstable and become too painful to bear weight on it. When an ACL tears it can bring an extreme amount of pain to the person. “Still, even after the swelling subsided, my knee didn’t feel right”, also said by Mike Swift in his article. When an ACL tears it can either be really painful right then and there or you won’t even feel pain at all. “I had felt the bones separate inside the joint in a way they never had before. But I wasn’t

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.

ACL injuries used to be seen as career ending injuries 50 years ago, however, throughout the years with the advancement in technology aiding treatment and rehabilitation procedures. Yet they are still sever and take months to recover. This is because of the precise location of the ligament within the knee joint. Resulting in no blood clot formation within the joint as a consequence scar tissue will not form and the tissue will just be filled with uncontrolled blood leading to swelling an pain within the joint (ACL reconstruction Oxford university hospital, 2017) which is why it takes between 9 to 12 months for recovery. With an ACL injury, other injuries often follow, namely MCL injuries and meniscal lesions which in time would likely lead to the patient contracting osteoarthritis due to it being a degenerative disorder consequently resulting from the meniscal and
