Maybe twisted my knee got some questions?

Ok so I was playing softball and i was catching. I dove for a ball and my foot went one way and my knee the other. So pretty much my knee twisted and I heard a pop. About a year ago I tore my acl on that same knee and I had surgery but I was released and all and everything was back to normal. I don't think I tore anything. Well hopefully not. But does that seem like a twisted knee to you? And if so what do I need to do and how long does it usually take to go back to normal?
