18 yr old daughter's knee pain

[hodgepodge722]

6 weeks ago my daughter's left knee buckled on her while dancing, then later again that night.  She was in pain but not too severe but over the course of the week it got much worse to the point of not wanting to even walk on it.  She later experienced sharp piercing pain while just sitting down and has buckled a few more times.  Trip to the e.r. showed no breaks. Crutches and brace were given.  Since then she saw an ortho. and had an MRI. He said she had a bone bruise.  She is convinced it isn't. She had one 4 yrs ago in the same knee and said this feels differently and is much worse.  Is it possible to get a bone bruise (or something similar) when there has been no "blow" to the knee?  And are MRI's easy to mis-read?  After 6 weeks, she is still in continual pain and it is worse at night.  It is keeping her from doing most activities.  Even walking bothers her.  (She played soccer for several years and has chronic tendonitis due to "kissing patellas" but this is clearly a different type of pain/location.)
