It may be a tendon. It can be caused by trying to ride in too high of a gear or from the seat being too high. Once you pull a tendon, adjusting the bike isn't going to fix it, it needs to be rested and healed. Have her take some ibuprofen and ice it down, relaxing for a few days. When you get her back on the bike, make sure she is in a low gear so she can pedal easily, and show her how to shift so she can always pedal easily - say at 60 rpms - and ensure her seat is adjusted right...both height and fore/aft. Rule of thumb to start:
With the pedal at the six o'clock (down) position, with her seated on the bike and her heel on the pedal, her leg should be fully extended.
With the pedal at the 3 o'clock position (forward), with her seated on the bike and her foot in her normal position on the pedal, the bone just below her kneecap should be aligned with the pedal spindle. (you can use a washer and piece of string like a plumb-bob to check this)
These are just rules of thumb, a starting point - and I am not a doctor!
"Let us hope our weapons are never needed --but do not forget what the common people knew when they demanded the Bill of Rights: An armed citizenry is the first defense, the best defense, and the final defense against tyranny. If guns are outlawed, only the government will have guns. Only the police, the secret police, the military, the hired servants of our rulers. Only the government -- and a few outlaws. I intend to be among the outlaws" - Edward Abbey
