What is the main focus when inspecting the knee during a physical assessment?

• A. Swelling, deformities, and alignment
• B. Range of motion and pain levels
• C. Muscle strength and coordination
• D. Patellar reflexes and sensory testing

Answer: (A)

The primary focus when inspecting the knee during a physical assessment is on swelling, deformities, and alignment. This involves visually assessing the knee for any signs of inflammation or swelling that may indicate injury or underlying joint issues. Deformities, such as varus or valgus deformities, can also reveal structural problems in the knee. Additionally, evaluating the alignment helps to determine whether the knee is positioned correctly in relation to the leg and the rest of the body, which is crucial for assessing proper biomechanics and function.

Other aspects of the knee assessment, such as range of motion and pain levels, are certainly important but typically follow the overall inspection. These components provide insights into function and discomfort but do not replace the foundational assessment of the knee's physical state regarding swelling and structural integrity. Similarly, muscle strength and coordination, as well as patellar reflexes and sensory testing, may form part of a comprehensive evaluation but do not focus on the visual assessment of the knee itself, which is where swelling, deformities, and alignment come into play.
