1.2.6 Knee Ligaments

Front

What are the main knee ligaments?

Back

The main knee ligaments include the Anterior Cruciate Ligament (ACL), Posterior Cruciate Ligament (PCL), Medial Collateral Ligament (MCL), and Lateral Collateral Ligament (LCL).

Front

What is the function of the Anterior Cruciate Ligament (ACL)?

Back

The ACL prevents the tibia from sliding too far forward relative to the femur and provides stability during movement.

Front

What is the function of the Posterior Cruciate Ligament (PCL)?

Back

The PCL prevents the tibia from sliding too far backward relative to the femur.

Front

What is the role of the Medial Collateral Ligament (MCL)?

Back

The MCL helps maintain stability in the knee by preventing excessive inward movement (valgus stress).

Front

What is the role of the Lateral Collateral Ligament (LCL)?

Back

The LCL provides stability by preventing excessive outward movement (varus stress) of the knee.

Front

What is a positive anterior drawer test indicative of?

Back

A positive anterior drawer test indicates an injury to the Anterior Cruciate Ligament (ACL).

Front

What bones are primarily affected by an ACL injury?

Back

The bones primarily affected by an ACL injury are the proximal tibia and distal femur.

Front

What is the normal range of motion (ROM) for knee flexion in adults?

Back

The normal range of motion for knee flexion in adults is typically between 135 to 150 degrees.

Front

What is the difference between a ligament and a tendon?

Back

Ligaments connect bone to bone, while tendons connect muscle to bone.

Front

What is the significance of the knee joint's stability?

Back

Knee joint stability is crucial for weight-bearing activities and prevents injuries during movement.
