Movement from the lower extremities of the human body depends on the strength, agility and flexibility of the knee. Bones, cartilage, muscles, ligaments and tendons assist with the knee getting the job done (NIH, n.d.). While supporting the body to walk, run and jump, the knee is at risk for enduring a torn anterior cruciate ligament (ACL). This type of injury can pose a threat to athletes and their careers. When the ACL is torn, the body will lose stability and the inability to bear the weight of the athlete. Sports competitors are vulnerable to enduring a torn ACL injury during their sports career due to the roughness when playing sports, female athletes having a higher risk, it is rated number one as the most common sports injury.…show more content…
The sports that are more inclined to suffer ACL tears include soccer, basketball, football and tennis (Souryal, n.d.). The University of California, San Francisco reveals that the “ACL injury has an annual incidence of more than 200,000 cases with ~100,000 of these knees reconstructed annually (Kim, 2009). The vulnerability of a torn ACL in athletes is 1,000 to one (Souryal, n.d.). //////////////////////////////
The ACL is the primary ligament which is considered as the stabilizer. The ACL is just one of four major ligaments of the joints within the knees (Kim, 2009). The posterior cruciate ligament (PCL), medial collateral ligament (MCL) and lateral collateral ligament (LCL) make up the other three ligaments that supports the knee joints. Signs and symptoms of a torn a torn ACL include swelling of the knee, pain that is intensified when the weight of the body is placed on it. The inability to bend the knee is another sign of a torn ACL due to the bleeding inside the joint (MedicineNet, n.d.).
Methods to diagnosis a torn ACL injury includes
• Lachman Test – Passive accessory movement that is used to assess both the single and sagittal plane instability (Physiopedia, n.d.). The body of the athlete is in a supine position while their knee is flexed to about 20 to 30 degrees as well as rotated externally. The physician or the physical therapist will then place their hands on both the tibia and the
