CCSP Sports Injury & Diagnosis — Questions and Answers
Question 1: What is the most common mechanism for an anterior cruciate ligament (ACL) injury in athletes?
- Direct blow to the thigh
- Overuse from running
- Twisting motion with planted foot (Correct answer)
- Jumping in place
Correct answer: Twisting motion with planted foot
The anterior cruciate ligament (ACL) is frequently injured during non-contact sports activities involving sudden changes in direction or landing. A common mechanism is a twisting motion of the knee while the foot is firmly planted on the ground, which places significant rotational stress on the ligament. This often occurs during cutting, pivoting, or hyperextension movements.
Question 2: Which special test is commonly used to evaluate a suspected rotator cuff tear?
- Lachman test
- Drop Arm test (Correct answer)
- Spurling’s test
- Phalen’s test
Correct answer: Drop Arm test
The Drop Arm test is a classic orthopedic special test specifically designed to assess the integrity of the rotator cuff, particularly the supraspinatus muscle. During the test, the patient attempts to slowly lower their arm from an abducted position, and an inability to do so smoothly or a sudden drop indicates a potential tear. This helps clinicians pinpoint the source of shoulder weakness and pain.
Question 3: What symptom is most associated with lateral epicondylitis (tennis elbow)?
- Pain in the medial elbow
- Swelling in the wrist
- Pain with resisted wrist extension (Correct answer)
- Numbness in the fingers
Correct answer: Pain with resisted wrist extension
Lateral epicondylitis, commonly known as tennis elbow, is an overuse injury affecting the tendons that attach to the lateral epicondyle of the elbow. The condition is characterized by pain and tenderness on the outside of the elbow, which is typically exacerbated by activities involving resisted wrist extension or gripping. This is because these actions engage the affected extensor muscles and their inflamed tendons.
Question 4: Which imaging method is best for identifying stress fractures?
- X-ray
- MRI (Correct answer)
- Ultrasound
- CT scan
Correct answer: MRI
While X-rays can sometimes show advanced stress fractures, Magnetic Resonance Imaging (MRI) is considered the gold standard for early detection and detailed evaluation of these injuries. MRI provides superior soft tissue contrast and can visualize the bone marrow edema associated with stress reactions and early stress fractures before they are visible on plain radiographs. This allows for timely diagnosis and intervention.
Question 5: What is the primary concern when evaluating a concussion?
- Elevated heart rate
- Loss of consciousness or confusion (Correct answer)
- Muscle spasms
- Knee instability
Correct answer: Loss of consciousness or confusion
When evaluating a concussion, the primary concern is assessing for signs of brain injury, such as loss of consciousness or any degree of confusion. These symptoms indicate an alteration in brain function following a head trauma and are critical indicators requiring immediate medical attention and removal from play. Early recognition helps prevent further injury and guides appropriate management.
Question 6: What condition is characterized by anterior knee pain and worsens with prolonged sitting?
- Meniscal tear
- ACL sprain
- Patellofemoral pain syndrome (Correct answer)
- Quadriceps strain
Correct answer: Patellofemoral pain syndrome
Patellofemoral pain syndrome (PFPS) is a common condition characterized by pain around or behind the kneecap, often referred to as "runner's knee" or "moviegoer's knee." The pain typically worsens with activities that increase pressure on the patellofemoral joint, such as prolonged sitting with bent knees, climbing stairs, or squatting. This is due to irritation of the cartilage or soft tissues surrounding the kneecap.
