What fans and media know about Beanie Wells' injured right knee fits in a medium-sized paragraph.
Wells suffered the injury against the Steelers last Sunday and has swelling. The knee is "stable", according to coach Ken Whisenhunt, and Wells won't knee surgery.
The unknown, however, takes several paragraphs to explore. We don't know what part of the knee is injured. We don't know what made the knee keep "locking up" on Sunday. Wells said it's not related to the knee surgery he underwent last season. And we don't know if it's related to the allergic reaction he had later to an injection. We don't know when Wells will return, so his availability for Sunday's game in Baltimore is in question. The "don't knows" go on and on.
I talked to Dr. Orr Limpisvasti, an orthopedic surgeon at Kerlan-Jobe Orthopaedic Clinic in Los Angeles, on Monday. Here's what Dr. Limpisvasti had to say about Wells' knee problem.
