In the 90-second musculoskeletal screening, which area is checked for symmetry and effusions?

• A. Knee and ankle
• B. Shoulder and elbow
• C. Wrist and hand
• D. Neck and thoracic spine

Answer: (A)

The main idea is to quickly detect joint problems by comparing both sides and looking for swelling inside a joint. In a fast musculoskeletal screen, you prioritize areas where differences between sides and signs of fluid buildup are most telling, so you can flag potential issues right away. The knee and ankle are ideal for this rapid check because they’re large, weight-bearing joints that commonly swell with injury or inflammation, and small differences between sides are easier to spot. Swelling in these joints—effusion—can appear quickly and is a clear signal that something may be wrong, warranting further evaluation. While other joints like the shoulder, elbow, wrist/hand, or the neck and thoracic spine can show problems, they’re not as straightforward to assess for symmetry and effusion in a quick screening. The knee and ankle provide a practical, reliable snapshot for a 90-second screen and help catch issues early.
