ACL Knee Injury
ACL knee injury is common in sports that involve sudden changes of direction, such as football, and soccer. Most occur during sudden twisting motion or when landing from a jump.
ACL Injury?
An anterior cruciate ligament injury is the over-stretching or tearing of the anterior cruciate ligament (ACL) in the knee. An acl tear may be partial or complete.
Medial collateral ligament (MCL) - runs along the inner part (side) of the knee and prevents the knee from bending inward.
Lateral collateral ligament (LCL) - runs along the outer part (side) of the knee and prevents the knee from bending outward.
Anterior cruciate ligament (ACL) - lies in the middle of the knee. It prevents the tibia from sliding out in front of the femur, and provides rotational stability to the knee.
Posterior cruciate ligament (PCL) - works with the ACL. It prevents the tibia from sliding backwards under the femur.
Causes for ACL Knee Injury
Direction change while running, pivoting, landing from a jump, or overextending the knee joint (called hyperextended knee), also can cause injury to the ACL.Basketball, football, soccer, and skiing are common causes of ACL tears.
Symptoms of ACL tear
A "popping" sound at the time of injuryKnee swelling within 6 hours of injury
Pain when you try to put weight on the injured leg
Restricted movement
Diagnosis for ACL tear
The pivot-shift test,anterior drawer test
the Lachman test
magnetic resonance imaging MRI
ReplyDeleteGreat post. I was once checking constantly this weblog and I'm impressed! Extremely useful information specially the closing part. I maintain such information much. I was once seeking this specific information for a very long time. Many thanks and best of luck.
ACL injuries most commonly occur during sports that involve sudden stops or changes in direction, jumping and landing — such as soccer, basketball, football and downhill skiing. Up to 80% of the knees will eventually develop a cartilage tear. The smooth Teflon lining of the knee which is known as articular cartilage is often damaged at the time of the ACL tear. If left untreated, this will again progressively wear at the knee, causing an increased rate of osteoarthritis development. ACL tears cannot be healed without ACL tear surgery in Mumbai.
