TRUE statement about Anterior cruciate ligament is
**Core Concept**
The anterior cruciate ligament (ACL) is a critical ligament in the knee joint that plays a key role in stabilizing the knee and preventing excessive forward movement of the tibia relative to the femur. The ACL is a type of fibrous connective tissue that consists of two main bundles: anteromedial and posterolateral.
**Why the Correct Answer is Right**
The ACL is a critical ligament in the knee joint that plays a key role in stabilizing the knee and preventing excessive forward movement of the tibia relative to the femur. The ACL is a type of fibrous connective tissue that consists of two main bundles: anteromedial and posterolateral. The ACL is injured frequently, particularly in sports that involve sudden stops, changes in direction, or jumping. The most common mechanism of ACL injury is a non-contact pivot landing, where the foot plants and the knee buckles inward. This type of injury can be diagnosed using physical examination and imaging studies such as MRI.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because the posterior cruciate ligament (PCL) is a different ligament that stabilizes the knee joint, but it is located posteriorly and is not directly related to the ACL.
**Option B:** This option is incorrect because the medial collateral ligament (MCL) is a ligament that stabilizes the knee joint, but it is located on the medial aspect of the knee and is not directly related to the ACL.
**Option C:** This option is incorrect because the lateral collateral ligament (LCL) is a ligament that stabilizes the knee joint, but it is located on the lateral aspect of the knee and is not directly related to the ACL.
**Clinical Pearl / High-Yield Fact**
A key clinical correlation to remember is that ACL injuries are often associated with other knee injuries, such as meniscal tears or medial collateral ligament (MCL) injuries. A thorough physical examination and imaging studies are essential in diagnosing and managing ACL injuries.
**Correct Answer:** C. The ACL is a type of fibrous connective tissue that consists of two main bundles: anteromedial and posterolateral.
