Therapeutic Arthroscopic Procedures Indian Medical PG Practice Questions and MCQs
Practice Indian Medical PG questions for Therapeutic Arthroscopic Procedures. These multiple choice questions (MCQs) cover important concepts and help you prepare for your exams.
Therapeutic Arthroscopic Procedures Indian Medical PG Question 1: The operative procedure known as "microfracture" is done for the
- A. Delayed union of femur
- B. Osteochondral defect of femur (Correct Answer)
- C. Non union of tibia
- D. Loose bodies of ankle joint
Therapeutic Arthroscopic Procedures Explanation: ***Osteochondral defect of femur***
- **Microfracture** is a surgical technique used to stimulate the growth of **fibrocartilage** in areas of damaged articular cartilage, such as an **osteochondral defect**.
- It involves creating small holes in the **subchondral bone** to allow stem cells and growth factors from the bone marrow to form a new reparative tissue.
*Delayed union of femur*
- **Delayed union** typically involves an extended time for fracture healing, which is often managed through prolonged immobilization, **bone grafting**, or sometimes revision surgery.
- Microfracture specifically targets cartilage repair, not the process of **bony union** after a fracture.
*Non union of tibia*
- **Non-union** refers to the failure of a fractured bone to heal within a reasonable timeframe, often requiring surgical intervention with **bone grafts** or **internal fixation**.
- This condition involves bone healing problems, distinct from cartilage defects that microfracture addresses.
*Loose bodies of ankle joint*
- **Loose bodies** in a joint are typically removed surgically, often arthroscopically, to relieve pain and prevent joint damage.
- This procedure does not involve the repair of cartilage defects, which is the primary goal of microfracture.
Therapeutic Arthroscopic Procedures Indian Medical PG Question 2: Dequervain's tenosynovitis is a stenosing tenosynovitis of the
- A. Median nerve
- B. Tendo Achilles
- C. Iliolumbar ligament
- D. First extensor compartment of the wrist (Correct Answer)
Therapeutic Arthroscopic Procedures Explanation: ***First extensor compartment of the wrist***
- **De Quervain's tenosynovitis** specifically involves the tendons of the **abductor pollicis longus (APL)** and **extensor pollicis brevis (EPB)** as they pass through the first dorsal extensor compartment of the wrist.
- Inflammation and thickening of the tendon sheaths within this compartment lead to **pain and tenderness** on the radial side of the wrist, aggravated by movements of the thumb and wrist.
*Median nerve*
- The **median nerve** is associated with **carpal tunnel syndrome**, which presents with numbness, tingling, and weakness in the thumb, index, middle, and radial half of the ring fingers.
- This condition involves compression of the median nerve as it passes through the carpal tunnel, not tenosynovitis of a specific tendon compartment.
*Tendo Achilles*
- The **Achilles tendon** is located at the back of the ankle and connects the calf muscles to the heel bone.
- Conditions affecting the Achilles tendon include **Achilles tendinopathy** or rupture, causing pain and stiffness in the heel, which is distinct from wrist pain.
*Iliolumbar ligament*
- The **iliolumbar ligament** connects the transverse process of the fifth lumbar vertebra to the iliac crest.
- Pain in this area is typically associated with **low back pain** or iliolumbar ligament sprain, not tenosynovitis in the wrist.
Therapeutic Arthroscopic Procedures Indian Medical PG Question 3: All are true about osteoarthritis, except
- A. Quadriceps atrophy (Correct Answer)
- B. MCP is spared
- C. Glucosamines are beneficial
- D. Loose bodies in the ankle joint
Therapeutic Arthroscopic Procedures Explanation: ***Quadriceps atrophy***
- While muscle weakness can occur in osteoarthritis due to pain and disuse, **quadriceps atrophy** is not a universal or defining characteristic of the disease itself, nor is it consistently observed as a primary feature.
- The statement implies that quadriceps atrophy is *always* true about osteoarthritis, which is incorrect as it's a potential consequence but not inherently present in all cases or a direct pathological feature.
*MCP is spared*
- The **metacarpophalangeal (MCP) joints** are typically spared in osteoarthritis, unlike in rheumatoid arthritis.
- Osteoarthritis predominantly affects the **distal interphalangeal (DIP)** and **proximal interphalangeal (PIP)** joints of the hands, as well as the **carpometacarpal (CMC) joint of the thumb**.
*Glucosamines are beneficial*
- **Glucosamine sulfate** is a commonly used supplement in osteoarthritis, with some studies suggesting it may provide modest pain relief and slow cartilage degradation in certain patients.
- While its efficacy is debated and not universally accepted as curative, many patients report subjective benefit, and it is considered a complementary therapy.
*Loose bodies in the ankle joint*
- **Loose bodies**, also known as joint mice, are fragments of cartilage or bone that can break off and float within the joint space.
- These are a recognized complication of osteoarthritis, particularly in weight-bearing joints like the **ankle**, and can cause locking or catching sensations.
Therapeutic Arthroscopic Procedures Indian Medical PG Question 4: An athlete sustained an injury around the knee joint, suspecting cartilage damage. Which of the following is the investigation of choice?
- A. Clinical examination
- B. Arthroscopy (Correct Answer)
- C. Arthrotomy
- D. X-ray
Therapeutic Arthroscopic Procedures Explanation: ***Arthroscopy***
- **Arthroscopy** is the definitive investigation for **cartilage damage** as it allows for direct visualization of the knee joint's internal structures.
- It not only confirms the diagnosis but can also facilitate simultaneous **repair or débridement** of damaged cartilage.
*X-ray*
- **X-rays** are primarily used to assess **bone structures** and detect fractures or significant joint space narrowing, not soft tissue injuries like cartilage.
- They are generally **insufficient** for diagnosing subtle or early cartilage damage.
*Clinical examination*
- A **clinical examination** is crucial for initial assessment and suspicion of cartilage injury, but it cannot definitively diagnose the extent or type of cartilage damage.
- It helps guide further investigations but is **not specific enough** to confirm cartilage integrity.
*Arthrotomy*
- **Arthrotomy** involves a larger incision to open the joint, which is more **invasive** than arthroscopy and typically reserved for open surgical repairs or complex reconstructions, not as a primary diagnostic tool for cartilage.
- It carries a **higher risk of complications**, such as infection and prolonged recovery, compared to arthroscopy.
Therapeutic Arthroscopic Procedures Indian Medical PG Question 5: Which of the following is NOT a complication of elbow dislocation?
- A. Vascular injury
- B. Median nerve injury
- C. Myositis ossificans
- D. Radial nerve injury (Correct Answer)
Therapeutic Arthroscopic Procedures Explanation: ***Radial nerve injury***
- The **radial nerve** is rarely injured in an elbow dislocation due to its anatomical course, which is less exposed to the shearing forces involved in this type of injury.
- While other nerves like the ulnar and median nerves are more susceptible, significant stretching or compression of the radial nerve is **uncommon** in typical elbow dislocations.
*Vascular injury*
- The **brachial artery** runs in close proximity to the elbow joint and can be torn or compressed during a dislocation, leading to **ischemia** if not promptly recognized and treated.
- This complication can result in **Volkmann's ischemic contracture** if perfusion is not restored.
*Median nerve injury*
- The **median nerve** passes anterior to the elbow joint and is vulnerable to injury from stretching or direct compression during dislocation.
- Injury can manifest as **sensory deficits** in the distribution of the median nerve and **weakness** of forearm pronation and thumb flexion/opposition.
*Myositis ossificans*
- This is a common chronic complication of elbow dislocations, particularly in cases of **delayed reduction** or aggressive physical therapy.
- It involves the **abnormal ossification** of soft tissues around the joint, commonly in the brachialis muscle, leading to **pain and restricted range of motion**.
Therapeutic Arthroscopic Procedures Indian Medical PG Question 6: A 65-year-old lady presented with a swollen and painful knee. On examination, she was found to have grade III osteoarthritic changes. What is the best course of action?
- A. Conservative management
- B. Total knee replacement (Correct Answer)
- C. Arthroscopic washing
- D. Partial knee replacement
Therapeutic Arthroscopic Procedures Explanation: ***Total knee replacement***
- For **grade III osteoarthritis** in a 65-year-old, a total knee replacement is the most definitive and effective treatment to relieve pain and restore function in a severely damaged joint.
- This procedure addresses widespread cartilage loss and structural changes typical of advanced osteoarthritis.
*Conservative management*
- This approach is typically favored for **mild to moderate osteoarthritis**, involving physical therapy, NSAIDs, and lifestyle modifications.
- For **grade III changes** with significant pain and swelling, conservative measures are unlikely to provide sufficient relief or halt disease progression effectively.
*Arthroscopic washing*
- **Arthroscopic lavage** and debridement are rarely recommended for osteoarthritis as they have not shown sustained benefits for pain or function.
- It is sometimes used for specific mechanical symptoms, but it does not address the underlying cartilage loss and structural damage in severe osteoarthritis.
*Partial knee replacement*
- A **partial knee replacement** is suitable when osteoarthritis is confined to a single compartment of the knee, and the other compartments are healthy.
- Given the indication of "grade III osteoarthritic changes" without specifying a single compartment, a total knee replacement is generally more appropriate for widespread disease.
Therapeutic Arthroscopic Procedures Indian Medical PG Question 7: What is the most effective management strategy for hemarthrosis?
- A. Immobilization with a P.O.P. cast
- B. Application of a compression bandage
- C. Needle aspiration to remove excess blood (Correct Answer)
- D. All of the options
Therapeutic Arthroscopic Procedures Explanation: ***Needle aspiration to remove excess blood***
- **Aspirating the blood** from the joint effectively reduces intra-articular pressure, pain, and inflammation.
- This procedure also helps prevent **synovial hypertrophy** and **cartilage damage** caused by the presence of blood in the joint.
*Application of a compression bandage*
- While helpful for reducing swelling and providing support, a **compression bandage alone** does not remove the accumulated blood.
- It may alleviate some discomfort but does not address the underlying issue of **intra-articular blood accumulation**.
*Immobilization with a P.O.P. cast*
- **Immobilization** can help rest the joint and reduce pain, but it does not remove the blood from the joint space.
- Prolonged immobilization can lead to **joint stiffness** and **muscle atrophy**, which are undesirable outcomes.
*All of the options*
- While compression and immobilization can be supportive measures, they are not the **most effective primary strategy** for managing hemarthrosis.
- The direct removal of blood via **aspiration** is crucial for alleviating pressure and preventing long-term joint damage.
Therapeutic Arthroscopic Procedures Indian Medical PG Question 8: Manoeuvre carried out for diagnosing medial meniscus injury is:
- A. McMurray's test (Correct Answer)
- B. Valgus stress test
- C. Lachmann's test
- D. Varus stress test
Therapeutic Arthroscopic Procedures Explanation: ***McMurray's test***
- This test is specifically designed to assess for meniscal tears, particularly the **medial meniscus**.
- A positive test involves eliciting a **click or pain** when extending the knee from a fully flexed position while internally and externally rotating the tibia.
*Valgus stress test*
- This test evaluates the integrity of the **medial collateral ligament (MCL)**.
- It involves applying a valgus (outward) force to the knee while stabilizing the thigh, looking for increased gapping or pain.
*Lachmann's test*
- This is the most sensitive test for assessing the integrity of the **anterior cruciate ligament (ACL)**.
- It involves gently pulling the tibia anteriorly with the knee flexed at 20-30 degrees, looking for excessive anterior translation.
*Varus stress test*
- This test assesses the integrity of the **lateral collateral ligament (LCL)**.
- It involves applying a varus (inward) force to the knee while stabilizing the thigh, looking for increased gapping or pain.
Therapeutic Arthroscopic Procedures Indian Medical PG Question 9: Hill-Sach's lesion is seen in:
- A. Anterior dislocation of hip
- B. Posterior dislocation of hip
- C. Recurrent dislocation of shoulder (Correct Answer)
- D. Posterior dislocation of shoulder
Therapeutic Arthroscopic Procedures Explanation: ***Recurrent dislocation of shoulder***
- A **Hill-Sach's lesion** is a **compression fracture** of the posterolateral part of the humeral head, occurring as the humeral head impacts the anterior rim of the glenoid during **anterior shoulder dislocation**.
- It is particularly associated with **recurrent anterior shoulder dislocations** due to repeated impaction.
*Anterior dislocation of hip*
- This condition involves the femoral head moving anteriorly out of the acetabulum and is not associated with a Hill-Sach's lesion.
- While it causes significant pain and immobility, the specific bone lesion known as Hill-Sach's involves the humerus, not the femur.
*Posterior dislocation of hip*
- A posterior hip dislocation involves the femoral head moving posteriorly out of the acetabulum and is not linked to a Hill-Sach's lesion.
- This type of injury is often seen in high-impact trauma, such as car accidents, and can be associated with acetabular fractures or sciatic nerve injury.
*Posterior dislocation of shoulder*
- This involves the humeral head dislocating posteriorly relative to the glenoid, and while bone lesions can occur, they are typically **reverse Hill-Sach's lesions** (on the anterior aspect of the humeral head) or **bony Bankart lesions** of the posterior glenoid.
- A standard Hill-Sach's lesion specifically refers to the posterolateral humeral head defect seen in **anterior dislocations**.
Therapeutic Arthroscopic Procedures Indian Medical PG Question 10: A 52-year-old female complains of increasing pain in the right shoulder. She is also finding it increasingly difficult to do overhead abduction of the affected joint. She had been diagnosed as a diabetic 20 years back and is on treatment since then. What is the most likely cause of her clinical condition?
- A. Frozen shoulder (Correct Answer)
- B. Bacterial arthritis
- C. Osteoarthritis
- D. Rotator cuff tear
Therapeutic Arthroscopic Procedures Explanation: ***Frozen shoulder***
- The patient's presentation with **increasing pain** and **difficulty with overhead abduction** of the shoulder, especially in the context of long-standing **diabetes**, is highly characteristic of **adhesive capsulitis** (frozen shoulder).
- This condition is marked by **progressive stiffness** and **restricted range of motion** in the shoulder joint due to inflammation and fibrosis of the joint capsule.
*Bacterial arthritis*
- **Bacterial arthritis** typically presents with an **acutely painful**, **swollen**, and **erythematous joint**, often accompanied by systemic symptoms like **fever** and **malaise**.
- The chronic, progressive nature of the patient's symptoms and the absence of acute inflammatory signs or fever make bacterial arthritis less likely.
*Osteoarthritis*
- While **osteoarthritis** can cause shoulder pain and stiffness, it usually presents with **pain that worsens with activity** and is relieved by rest, often with **crepitus** and a more gradual loss of range of motion.
- The pronounced restriction in **overhead abduction** in this patient, particularly given the diabetic history, points away from primary osteoarthritis as the most likely cause.
*Rotator cuff tear*
- A **rotator cuff tear** typically presents with pain and weakness, especially during **abduction** or **external rotation**, and may have a specific mechanism of injury.
- While abduction can be difficult, the classic presentation of a frozen shoulder with severe, global restriction of both active and passive range of motion is a stronger fit for the described symptoms.
