1.2.6 Knee Ligaments

Front

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

Back

The ACL helps maintain stability in the knee by preventing excessive anterior translation (forward movement) of the tibia relative to the femur.

Front

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

Back

The PCL prevents excessive posterior translation (backward movement) of the tibia relative to the femur.

Front

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

Back

The MCL provides stability to the inner (medial) side of the knee and prevents excessive valgus (inward) movement.

Front

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

Back

The LCL provides stability to the outer (lateral) side of the knee and prevents excessive varus (outward) movement.

Front

What does a positive Anterior Drawer test indicate?

Back

A positive Anterior Drawer test indicates potential injury to the ACL, suggesting increased anterior laxity of the knee.

Front

What does a positive Varus stress test indicate?

Back

A positive Varus stress test indicates potential injury to the LCL, suggesting increased lateral laxity of the knee.

Front

What is the significance of performing Passive Range of Motion (PROM) before Active Range of Motion (AROM) after knee surgery?

Back

PROM allows gradual restoration of range of motion without risking further damage to the ligaments, which is crucial in the early stages of recovery.

Front

What are common symptoms of a knee ligament injury?

Back

Common symptoms include swelling, pain, instability, and difficulty bearing weight on the affected leg.

Front

What is the difference between a sprain and a strain?

Back

A sprain involves injury to ligaments, while a strain involves injury to muscles or tendons.

Front

What is the typical recovery time for an ACL tear?

Back

Recovery time for an ACL tear can range from 6 to 12 months, depending on the severity of the injury and the treatment approach.
