Total questions: 17
Worksheet time: 9mins
a) What is the primary function of the anterior cruciate ligament (ACL)?
Stabilizing the shoulder joint
Stabilizing the knee joint
Stabilizing the hip joint
Stabilizing the ankle joint
Where does the ACL attach on the tibia?
Tibial tuberosity
Anterior intercondylar area
Posterior intercondylar area
Medial tibial plateau
The ACL is most commonly injured during which type of activity?
Slow walking
Swimming
Jumping and pivoting sports
Weight lifting
Which of the following is a common mechanism of ACL injury?
Direct blow to the lateral side of the knee
Sudden deceleration and change in direction
Falling directly on a flexed knee
Repeated low-impact stress
The ACL is one of how many major ligaments stabilizing the knee joint?
Two
Three
Four
Five
Which special test is commonly used to assess ACL integrity?
McMurray’s test
Lachman test
Varus stress test
Apley’s compression test
Which of the following symptoms is most associated with an acute ACL tear?
Gradual knee swelling over weeks
Clicking sensation in the hip
Immediate swelling and instability of the knee
Dull, localized pain around the patella
What imaging technique is most commonly used to confirm an ACL injury?
X-ray
CT scan
MRI
Ultrasound
What is the main function of the posterior cruciate ligament (PCL)?
Prevent anterior translation of the tibia on the femur
Prevent posterior translation of the tibia on the femur
Provide valgus stability to the knee
Resist medial rotation of the femur
Which of the following is the most common cause of a PCL injury?
Twisting injury during sports
Hyperextension of the knee
Direct blow to the tibia when the knee is flexed (e.g., dashboard injury)
Sudden deceleration while running
Compared to ACL injuries, PCL injuries are generally:
More common and more severe
Less common and less likely to require surgery
Equally common but harder to diagnose
Only seen in elderly populations
Which of the following is most likely a symptom of PCL injury?
Popping sensation with immediate swelling
Pain and instability when walking downhill or downstairs
Locking of the knee
Lateral knee pain only
Which zone of the flexor tendon is referred to as “no man's land” due to difficulty in surgical repair and risk of adhesions?
Zone I
Zone II
Zone III
Zone IV
An injury to the flexor digitorum profundus (FDP) tendon typically results in inability to:
Extend the proximal interphalangeal (PIP) joint
Flex the distal interphalangeal (DIP) joint
Abduct the fingers
Extend the metacarpophalangeal (MCP) joint
What is the hallmark clinical sign of an extensor tendon injury in Zone I?
Inability to flex the DIP joint
Hyperextension of the MCP joint
Drooping of the DIP joint
Inability to flex the PIP joint
Which of the following is a complication of flexor tendon repair?
Trigger finger
Carpal tunnel syndrome
Adhesion and limited range of motion
Avascular necrosis of the scaphoid
Flexor tendon gliding exercises are typically introduced during rehabilitation to:
Strengthen the tendons immediately
Reduce swelling in the wrist
Prevent adhesions and promote tendon mobility
Improve vascular supply to the nerves
