Tom is a 23 year old Biology student. Today, as he got off the bus, he
twisted his knee. He comes to you, his doctor, four hours later with a
knee that is evidently inflamed and painful. Tom blushes as he tells
you how stupid this accident was.

Oh, there's something else. As he was showering before coming to the
Hospital (never let a doctor examine you while sweaty), his knee
throbbed in the strangest way and when Tom looked, he could have sworn
he saw a couple of pixie hands pushing out from inside his knee,
trying to get out. However, Tom's pretty sure he imagined it.

Tom isn't allergic to any medication. Aspiration of his knee produces
a bloody liquid.

Please indicate which of the following is the cause of Tom's condition
(2 points)

1) Lesion of crossed anterior ligament

2) Lesion of his interior meniscus

3) Tom is pregnant of a pixie, a condition he most probably acquired
in a Biology field trip. A C-section of his knee is indicated, which
will result in a release of the impish child and immediate relief of
pain.

4) Tom was pregnant, but shoving a needle into his knee wasn't such a
good idea. We can now conclude Tom has had a knee abortion brought
about by Medical malpractice.

5) 1 and 3 are correct.
