Damage to cruciate ligaments, which crisscross the knee to give it stability, is one of the most common sports injuries.
It is the first thing that comes to mind when they hurt their knee on the field; for many it is their greatest fear.
It can mean losing the chance to get that scholarship for young athletes, and it can also mean the end of those million dollar paychecks for those who have gone professional. A torn ACL can result in numerous surgeries, months of vigorous exercise and rehabilitation, and a sufficient amount of pain.
It requires complete patience, for pushing too hard can result in further, more painful injury. Even after all that, an athlete is not guaranteed he or she will ever be able to play sports again. The anterior cruciate ligament is the reason that the knee only has one pattern of movement.
Instead of moving sideways and up and down, the knee only serves as a pivot for flexion bending and extension straightening ; it holds the tibia and femur in place northstar. Obviously this asset makes it an essential to have a functioning ACL while playing sports. It is an especially common injury in soccer, which is a game of constant abrupt stops.
Not only is soccer a danger to the ACL because of its constant stops and starts, it is also a game of jumps, falls, and slide-tackles, which put a continuous stress on the ACL for the entire 90 minutes of the game.
ACL tears are also more common in women. The ACL is the most frequently injured part of the knee when related to sports.
As fore-mentioned, the ACL aids us in abrupt stops; it are these abrupt stops that are the most common cause for its injury. An ACL injury has not been scientifically proven to be linked to weight, size, or strength Duff The cause can be a violent twist of the knee, or it can simply be caused by standing up too fast.
It can be twisted or hyper extended. In any case, if it is concluded that the ACL has been ruptured, the symptoms and treatment remain the same. In any injury tiny, or large, blood vessels are broken, resulting in bleeding into the area of the injury.
This is the cause of swelling. In an ACL tear, the knee swells almost immediately because of the broken blood vessels in the ligament Sechrest. In some cases, the knee actually subluxes, which is a dislocation that pops back into place on its own.
In these cases, there is usually more injured than just the ACL. Often the MCL medial collateral ligament is also injured Sechrest. Other common symptoms, according to the northstar website are pain and the athlete falling to the ground as a result of the instability, or buckling, of the knee.
The other hand is placed on the tibia shin and tries to move it forward, without rotation. The physical examination is also given using the Anterior Drawer test Fig. Unfortunately, sometimes there is too much swelling in the knee to get accurate results from these tests.
X-rays can then be done to rule out the possibility of fractures or chipping of the knee joint, which can also cause blood in the joint.
If there is still doubt, an MRI can be done. MRI is an abbreviation for magnetic reconnaissance image. An MRI allows doctors to choose which layer of the anatomy they wish to see, and show a much clearer view of the area under inspection.
For even more evidence that there is actually a tear an arthroscopy is performed, but usually this procedure is left for surgical, not diagnostic purposes.
An arthroscopy entails a small camera being placed in the knee joint to look directly at the ACL. Once it is determined that the ACL has in fact been torn, the athlete must prepare for reconstructive surgery.
Many orthopedic choose to wait for the knee to stop swelling and regain some of the normal range of motion through light physical therapy for several weeks before going into surgery.
The athlete is also fitted with a brace to help maintain some stability that is worn at all times before and up to about six weeks after surgery.
The most often performed surgery is arthroscopic surgery. In this surgery, a small incision is made for the tiny camera which will guide the surgeon.
To reconstruct the ACL, the surgeon will generally harvest, or take, one third of the patellar tendon. Usually it will be the central third that will be used in order to leave the two ends easily re-attachable.
Attached to the graft the patellar tendon are pieces of bone which will prevent the tendon from sliding out of place once attached to the tibia and femur. Holes are then drilled into the femur and tibia at the attachment sites. The tendon, which will now be the reconstructed anterior cruciate ligament, is then threaded through the holes and held in place by metal screws.anterior cruciate ligament General introduction.
Located in the centre of the knee, the anterior cruciate ligament (ACL) is a strong band of tissue that prevents the shin bone (tibia) from extending excessively beyond the thigh bone (femur) yunusemremert.com ACL stands anterior cruciate ligament for and is one of two ligaments that crisscross within the knee.
This ligament is important for stability in side to side motions. The ACL is commonly torn while playing basketball, soccer, or any other sport requiring quick turns or yunusemremert.com://yunusemremert.com The anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) form an "X" on the inside of the knee and prevent the knee from sliding back and forth.
These limitations on knee movement allow the knee to concentrate the forces of the muscles on flexion and yunusemremert.com://yunusemremert.com · 3 1.
Introduction The anterior cruciate ligament (ACL), located between the femur and the tibia (Figure 1) is responsible for the mechanical stability of the knee yunusemremert.com Assignment_SchotTM_ Artwork: Anterior Cruciate Ligament and Orthopedic Surgeon Essay Anterior Cruciate Ligament Anterior cruciate ligament injuries affect athletes worldwide for various reasons.
Sometimes it has to do with a lack of strength in the knee, whereas other times this injury is due to contact. The anterior cruciate ligament (ACL) plays an important role in the control of knee stability by not only controlling anterior tibial translation but also varus movement and axial yunusemremert.com › Home › Free essays › Health essays.
