As we've been reporting, TNA star Kurt Angle has been in bad physical condition lately. Despite his claims that his health is fine (and being able to put on good TV matches), he was barely able to move around behind the scenes. There was even a photo of him sitting in a wheelchair circulating online last week.

It was recently discovered that Angle has no ACL cartilage left in his knee. Chris Jericho worked with a similar condition several years ago and part of his ACL cartilage eventually grew back.
