Sports Medicine Practice Questions

Q: Cozen's test is used for the diagnosis of ?

Tennis elbow. ***Tennis elbow*** - Cozen's test is a specific orthopedic test used to assess for **lateral epicondylitis**, also known as **tennis elbow**. - It involves extending the patient's elbow, pronating the forearm, and resisting wrist extension, which elicits pain at the **lateral epicondyle** in positive cases. *Medial epicondylitis (Golfer's elbow)* - Medial epicondylitis is tested by forcefully **flexing the wrist** against resistance, which would reproduce pain at the **medial epicondyle**. - While an elbow condition, it involves the tendinous origin of the **flexor-pronator mass**, distinct from the extensors involved in tennis elbow. *Olecranon bursitis* - Olecranon bursitis typically presents with **swelling and tenderness** directly over the **olecranon bursa** at the posterior aspect of the elbow. - Diagnosis is usually made by physical examination, observing the characteristic swelling, and does not involve specific provocative tests like Cozen's. *Carpal tunnel syndrome* - Carpal tunnel syndrome involves compression of the **median nerve** at the wrist, causing **numbness, tingling, and weakness** in the hand. - Diagnostic tests include **Phalen's maneuver** and **Tinel's sign** at the wrist, which are unrelated to elbow pain or Cozen's test.

Q: Which of the following is a cause of painful arc syndrome?

Supraspinatus tendinitis. ***Supraspinatus tendinitis*** - **Supraspinatus tendinitis** causes inflammation of the supraspinatus tendon, leading to impingement under the acromion during abduction. - This impingement typically results in a **painful arc** between 60° and 120° of abduction, as the inflamed tendon gets pinched. *Subacromial bursitis* - **Subacromial bursitis** is inflammation of the bursa located between the rotator cuff tendons and the acromion. - While it can cause shoulder pain and limit abduction, the pattern of pain with a distinct "painful arc" is more characteristic of **supraspinatus tendinitis** or other rotator cuff pathologies. *Fracture of greater tuberosity* - A **fracture of the greater tuberosity** is an acute bone injury that causes sudden, severe pain and significantly limits all shoulder movements due to structural damage. - The pain is constant and not typically limited to a specific range of motion like a "painful arc," which is more indicative of soft tissue impingement.

Q: Painful arc syndrome pain is felt during which range of shoulder abduction?

Mid abduction. **Mid abduction** - Painful arc syndrome, often associated with **rotator cuff tendinopathy** or **subacromial impingement**, typically causes pain between **60 and 120 degrees of abduction**. - This range is when the rotator cuff tendons are most likely to be compressed beneath the **acromion**. *Initial abduction* - Pain during initial abduction (0-60 degrees) might suggest conditions like **adhesive capsulitis (frozen shoulder)** or **glenohumeral joint arthritis**. - These conditions typically involve pain throughout the range of motion or at the extremes. *Full range of abduction* - Pain throughout the entire range of motion, rather than a specific arc, is more characteristic of **generalized shoulder inflammation** or **severe arthritis**. - In painful arc syndrome, pain often *subsides* after 120 degrees as the rotator cuff clears the subacromial space. *Overhead abduction* - While overhead activities can exacerbate shoulder pain, the defining feature of painful arc syndrome is the pain specifically during the **mid-range of abduction**, not necessarily only at overhead positions. - Pain in extreme overhead positions could indicate instability or severe impingement but isn't the primary descriptor of a painful arc.

Q: What is the most likely diagnosis based on the provided image?

Popeye's sign. ***Popeye's sign*** - The image shows a prominent bulge in the distal upper arm, which is characteristic of the **Popeye's sign**. - This sign indicates a **rupture of the long head of the biceps brachii tendon**, where the muscle belly retracts distally creating a visible lump. *Griesinger sign* - The **Griesinger sign** refers to edema and tenderness over the postero-inferior aspect of the mastoid process. - This sign is associated with **septic thrombosis of the mastoid emissary vein** or superior sagittal sinus thrombosis. *Rising sun sign* - The **rising sun sign** is a neuroimaging finding, referring to the upward displacement of the third ventricle and elevation of the cerebral hemispheres. - It is typically seen in cases of **hydrocephalus** or large suprasellar masses displacing brain structures. *Winner sign* - The **Winner sign** is a radiological finding seen in developmental dysplasia of the hip (DDH), specifically referring to a line drawn from the lateral corner of the acetabulum to the femoral shaft. - It assesses the **coverage of the femoral head** by the acetabulum, and its absence or abnormal position indicates DDH.

Q: Medial snapping knee syndrome is due to involvement of -

Pes Anserinus. ***Pes Anserinus*** - The **pes anserinus bursa** and its associated tendons (sartorius, gracilis, semitendinosus) can cause medial knee pain and snapping if inflamed or irritated. - This is a common cause of **medial snapping knee syndrome**, particularly in athletes or individuals with valgus deformity. *Quadriceps Tendon* - The **quadriceps tendon** is located anteriorly, connecting the quadriceps muscles to the patella, and is not typically involved in medial snapping. - Issues with the quadriceps tendon usually present as anterior knee pain or tendinitis. *Gastrocnemius origin* - The **gastrocnemius origin** is at the distal femur and its involvement would typically cause posterior knee pain or symptoms related to calf muscle function. - It does not commonly cause medial knee snapping. *Lateral collateral ligament* - The **lateral collateral ligament (LCL)** is on the lateral side of the knee and its involvement would cause lateral knee pain or instability. - It is not associated with medial snapping knee syndrome.

Q: Lift off test is done to assess the function of:

Subscapularis muscle function. ***Subscapularis muscle function*** - The **Lift-off test**, or Gerber's Lift-off test, specifically assesses the integrity and strength of the **subscapularis muscle** by evaluating its internal rotation and extension strength. - A positive test occurs when the patient is unable to lift their hand off their back, indicating a **subscapularis tear or weakness**. *Supraspinatus muscle function* - The **supraspinatus muscle** is primarily tested with the **empty can test** or full can test, which assess its role in shoulder abduction. - These tests evaluate for **impingement** or **tears** of the supraspinatus tendon. *Infraspinatus muscle function* - The **infraspinatus muscle** is mainly responsible for external rotation and is assessed using tests like the **resisted external rotation test** with the arm at the side. - This test is used to detect **infraspinatus tears** or weakness. *Teres Minor muscle function* - The **teres minor muscle** also contributes to external rotation of the shoulder, often tested in conjunction with the infraspinatus. - Its function can be isolated by testing resisted **external rotation** in 90 degrees of abduction and external rotation.

Q: Which ligament is most commonly damaged in knee injuries?

ACL. ***ACL*** - The **anterior cruciate ligament (ACL)** is highly susceptible to injury, especially during sports involving sudden stops, changes in direction, jumping, and awkward landings. - Its role in stabilizing the knee against **anterior tibial translation** and rotational forces makes it vulnerable to tears. *PCL* - The **posterior cruciate ligament (PCL)** is much stronger than the ACL and less frequently injured, typically requiring a direct blow to the flexed knee (e.g., dashboard injury). - It prevents **posterior tibial translation** relative to the femur. *MCL* - The **medial collateral ligament (MCL)** is commonly injured, often due to a direct blow to the outside of the knee causing a **valgus stress**. - While frequently damaged, it is often injured in conjunction with the ACL but the ACL is more frequently injured in isolation. *LCL* - The **lateral collateral ligament (LCL)** is the least commonly injured of the four major knee ligaments. - It usually results from a direct blow to the inside of the knee causing **varus stress**.

Q: Most common site of osteochondritis dissecans?

Lateral part of the medial femoral condyle. ***Lateral part of the medial femoral condyle*** - This is the **most common site** for osteochondritis dissecans in the knee, accounting for about 85% of cases. - The condition involves a localized area of **osteonecrosis and subchondral bone separation** from the epiphysis, typically afflicting this specific load-bearing region. *Medial part of the medial femoral condyle* - This location is **less common** for osteochondritis dissecans compared to the lateral aspect of the medial femoral condyle. - While osteochondral lesions can occur on any part of the condyle, the specific biomechanical stresses make the lateral part more susceptible. *Lateral part of the lateral femoral condyle* - Osteochondritis dissecans is **rarely found** in this location. - The lateral femoral condyle is generally less involved in osteochondritis dissecans of the knee. *Medial part of the lateral femoral condyle* - This site is also an **uncommon location** for osteochondritis dissecans. - The disease has a strong predilection for the medial femoral condyle, particularly its lateral aspect.

Q: Painful arc syndrome is caused by impingement of ?

Rotator cuff tendon. ***Rotator cuff tendon*** - Painful arc syndrome, or shoulder impingement syndrome, is most commonly caused by the **compression of the rotator cuff tendons** between the humeral head and the acromion, especially during abduction. - The supraspinatus tendon, being the most superiorly located of the rotator cuff tendons, is particularly susceptible to **impingement** and subsequent inflammation or tearing within the subacromial space. *Subdeltoid bursa* - While inflammation of the subdeltoid bursa (subdeltoid bursitis) can cause shoulder pain, it is often a **secondary finding** due to irritation from underlying rotator cuff pathology rather than the primary site of impingement in painful arc syndrome. - The subdeltoid bursa, located beneath the deltoid muscle, **facilitates smooth movement** but is not the most direct structure compressed during the classic "painful arc" motion. *Biceps tendon* - Impingement of the biceps tendon (specifically the long head of the biceps) can occur, but it typically presents as **anterior shoulder pain** and may be associated with biceps tendinopathy or superior labral tears, rather than the classic painful arc presentation involving abduction. - While the biceps tendon can be involved in shoulder pain, it is **less commonly the primary source** of the "painful arc" during abduction compared to the rotator cuff tendons. *Subacromial bursa* - The subacromial bursa is a fluid-filled sac that lies between the rotator cuff tendons and the acromion, and its inflammation (subacromial bursitis) is a frequent component of **shoulder impingement syndrome**. - However, the impingement itself is primarily of the **rotator cuff tendons**, and the bursa becomes inflamed as a result of the compression and friction, acting as a secondary structure rather than the primary impinged tissue.
