Grade I ligament injury can be described as:

• A. No symptoms.
• B. Mild pain and minimal functional loss, recovering in 1 to 2 weeks.
• C. Moderate loss of function with recovery in 3 to 6 weeks.
• D. Severe pain with near complete loss of function.

Answer: (B)

In ligament injuries, grading shows how much damage the fibers have sustained and how stable the joint remains. Grade I is a mild sprain where only a small number of ligament fibers are stretched or slightly torn, so the joint stays stable and function is largely preserved. Symptoms are mild—some pain and tenderness with little swelling—yet the affected limb can typically bear weight and move with minimal limitation. Recovery is quick, usually about 1 to 2 weeks, because there isn’t significant tissue disruption. The other descriptions reflect more severe injuries: no symptoms would mean no sprain, moderate functional loss over several weeks aligns with a Grade II sprain, and severe pain with near-complete loss of function aligns with a Grade III sprain involving a more complete tear and greater instability.
