Rovsing's sign is indicative of which condition?

Rovsing's sign is a clinical indicator often associated with appendicitis, particularly in cases of acute abdomen. This sign is elicited during a physical examination when pressure is applied to the left lower quadrant of the abdomen, leading to pain in the right lower quadrant. This response indicates irritation of the peritoneum, typically due to an inflamed appendix.

In the context of a ruptured appendix, Rovsing's sign is an important part of the assessment as it helps confirm the suspicion of acute appendicitis. If the appendix is inflamed or infected, palpating the opposite side can intensify the pain due to the mechanics of referred pain and the inflammatory process affecting the peritoneum.

The other options do not relate to Rovsing's sign. Knee instability and meniscal damage pertain to orthopedic evaluations and do not involve abdominal signs or symptoms. Acute cholelithiasis, or gallbladder stones, may present with abdominal pain but typically would not elicit a positive Rovsing's sign. Therefore, the connection between Rovsing's sign and acute abdomen due to appendicitis underscores its clinical significance in diagnosis.
