Grade III Sprain/Strain

• A. some pain, minimal loss of function, no abnormal function, & mild point tenderness
• B. moderately painful with swelling and limited movement
• C. pain with full function and no swelling
• D. extremely painful, inevitable loss of function, swelling

Answer: (D)

In sprains and strains, severity is graded from I to III based on tissue damage and functional impairment. Grade III represents a complete tear with the most serious disruption, leading to extreme pain, a substantial loss of function, and noticeable swelling. This is why the description “extremely painful, inevitable loss of function, swelling” best fits Grade III.

For contrast, mild pain with minimal loss of function aligns with a Grade I injury, while moderate pain with swelling and limited movement fits Grade II. Pain with full function and no swelling is inconsistent with a sprain/strain of significant severity, making it unlikely to be a Grade III.
