An out-of-shape, recently divorced, 42-year-old man is trying to impress a young woman by challenging her to a game of tennis. In the middle of the game, a loud"pop" (like a gun shot) is heard, and the man falls to the ground clutching his ankle. He limps off the court with pain and swelling in the back of the lower leg. Although he can still weakly plantar-flex his foot, he seeks medical help the next day because of persistent pain, swelling, and limping. He can put weight on that foot with no exacerbation of the pain, but the motion of taking a step is painful. Which of the following would be the most likely finding on physical examination?
A. Tapping on the calcaneus is extremely painful
B. The ankle joint can be abducted farther out than the normal contralateral side
C. The ankle joint can be adducted farther in than the normal contralateral side
D. There is a gap in the Achilles tendon easily felt by palpation
E. There is crepitation and grating by direct palpation over either malleoli
