Transcript of ACL Tear

Alexa Williams, Faunte Thompson, Miranda Ellis General Information Cause/Risk Factors/ How it Happens Signs & Symptoms Genu Valgum aslo known as knock knee is a deformity. ACL Tear Ligament- band of tissue that connects 2 or more bones Connects femur to tibia Gives Rotational Stability Most commonly injured ligament Genu valgum-also known as knock knee, knees angle in and touch each other Genu valgus-adduction-internal rotation mechanism of ACL injury 70% of Injury occurs through non contact Associated with deceleration, pivoting, cutting, side step, awkward landing Patients experience pain and swelling, unstable Femur and tibia become unconnected when the ACL tears Loss of motion, discomfort, increased forward movement of tibia in relation to femur, mushy endpoint, pop 3 grades of sprains (tears) 50% occur in combination with damage to meniscus, articular cartilage, and other ligaments Occurs in females more than males About 200,000 ACL injuries annually, and half are reconstructed When children are born with this, they go through exercise and stretches to try and get the knee to remain in a stable upright position. If you are born with Genu Valgum you are more likely to tear your ACL during sport. Once you have torn your
ACL symptoms can be:
•Limited movement
•Unstable or buckling knee Treatment When tearing
your ACL you
do not always need surgery,
but most of
the time you
do. This is
the inner
muscle of
you knee
as your
ACL, and
in this
it is torn. Directly after you tear your ACL you should:
*apply ice
*take a pain killer
*apply bandage
Do this until you can see a Doctor. If you have an avulsion fracture you will need surgery in which they reconstruct the entire knee. Reattaching the bone fragment as well. Once you have your surgery you will go through therapy to regain the strength and ability to perform back to your knee. Prevention & Risk Reduction performing training drills that require balance, power and agility such as jumping, and balance drills helps improve neuromuscular conditioning and muscular reactions and ultimately shows a decrease in the risk Phases of the ACL Injury Prevention Program should be performed at least 2-3 times per week during the season and includes:
Warm Up
Agility Drills
Cool Down Female athletes who participate in cutting and jumping sports are 5 times more likely to suffer a knee injury than a male athlete. Videos on exercises -http://www.strengthcoach.com/public/1641.cfm Long-term There are few long term prospective studies but a number of retrospective studies with follow-up times between 5 and 20 years have been published. These studies show that radiographic gonarthrosis is significantly increased after all knee injuries compared with the uninjured joint of the same patient Isolated meniscus rupture and subsequent repair, or partial or total ruptures of the ACL without major concomitant injuries, seem to increase the risk 10-fold people with an ACL tear sustain damage to the surrounding cartilage that worsens over time. MRI to show that reconstructing the anterior cruciate ligament (ACL) after an ACL tear protects patients from developing osteoarthritis. Lateral view of the knee using T2 mapping demonstrates abnormal cartilage in the central area of the tibia (shin bone), as well as in the area not involved in the initial "bone bruise". Dr. Potter, Chase and Stephanie Coleman Chair in MRI Research, said, “There is an increased rate of progressive cartilage damage in other areas of the leg that were unaffected by the initial impaction injury. ACL reconstruction can slow down this damage.” THE END .....

ANY QUESTIONS During the surgery your doctor will do a graft, depending on your type of tear will choose the type of graft you recieve.
-cadaver graft Autograft: Central one-third patellar tendon, quadrupled hamstring tendon, and quadriceps tendon. (with or without bone block) Allograft tissue: patellar tendon and the Achilles tendon.(bone blocks) Soft tissue: semitendinosus, tibialis anterior/posterior, peroneus longus, and iliotibial band. Cadaver Graft: From a dead body. This graft is not typically used on younger people because it is more likely for failure. Getting a graft is serious surgery but also can increase recovery time by a lot. Over the age of 40 you should get a cadaver graft, you will recover much faster. Recovery Time:
1-4 weeks on crutches
2-4 months full recovery ( full running, lower body workouts) Athletes participating in sports such as football, basketball, soccer, tennis, and rugby are at risk for ACL injuries most commonly.
