Pain down the side of my knee, that feels worse after activity. It also catches, and locks. Plus hip and ankle pain.

I hurt it again after jumping two stairs on my way to work.

I'm not sure about ACL! The MCL tear was diagnosed by the on campus doctor at my university. He didn't send me for scans or anything though.
