The two ligaments are called "cruciform" ligaments, as they are arranged in a crossed formation. In the quadruped stifle joint (analogous to the knee), based on its anatomical position, it is also referred to as the cranial cruciate ligament. [1] The term cruciate is Latin for cross. This name is fitting because the ACL crosses the posterior ...
An anterior cruciate ligament injury occurs when the anterior cruciate ligament (ACL) is either stretched, partially torn, or completely torn. [1] The most common injury is a complete tear. [1] Symptoms include pain, an audible cracking sound during injury, instability of the knee, and joint swelling. [1]
Cruciate ligaments. Cruciate ligaments occur in the knee of humans and other bipedal animals and the corresponding stifle of quadrupedal animals, and in the neck, fingers, and foot. The cruciate ligaments of the knee are the anterior cruciate ligament (ACL) and the posterior cruciate ligament (PCL). These ligaments are two strong, rounded bands ...
Anterior cruciate ligament tear seen on MRI. An anterior cruciate ligament injury results from excess tension on the ligament. This can come from a sudden stop or twisting motion of the knee. A few initial symptoms include swelling, knee instability, and pain. A popping sound or sensation may or may not be heard when the ACL first tears.
Injuries to the PLC often occur in combination with other ligamentous injuries to the knee; most commonly the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL). [2] As with any injury, an understanding of the anatomy and functional interactions of the posterolateral corner is important to diagnosing and treating the injury.
Typically there is a tear of the anterior cruciate ligament, posterior cruciate ligament, and either the medial collateral ligament or lateral collateral ligament. [3] If the ankle–brachial pressure index is less than 0.9, CT angiography is recommended to detect blood vessel injury. [3] Otherwise repeated physical exams may be sufficient. [2]
A soft tissue injury is the damage of muscles, ligaments and tendons throughout the body. Common soft tissue injuries usually occur from a sprain, strain, a one-off blow resulting in a contusion or overuse of a particular part of the body. Soft tissue injuries can result in pain, swelling, bruising and loss of function. [1]
A grade 1 sprain is defined as mild damage to a ligament or ligaments without instability of the affected joint. A grade 2 sprain is considered a partial tear to the ligament, in which it is stretched to the point that it becomes loose. A grade 3 sprain is a complete tear of a ligament, causing instability in the affected joint. [3]
