Criminal Sentence 238: Apples to Oranges

From today's paper, about shoulder surgery for pitchers:

"Unlike muscles in the rotator cuff, which can be strengthened and regrown, surgery is the only way to repair a labrum tear."

So, surgery is unlike muscles in the rotator cuff? Ah, no. I think we need to redo this whole sentence to avoid a comparison mistake:

"Muscles in the rotator cuff can be strengthened and regrown; on the other hand, a labrum tear can be repaired only by surgery."

Although this new sentence is in passive voice, it is much better than the original.
