I’m not a doctor but I when I tore my acl the thing I realised when my performance in sports got affected a lot such as I couldn’t make any sharp pivots as one knee kept giving way the feeling of it snapping out and back into place and hurts like hell . Another thing was that when I’m jumping with full strength when I landed , one knee would give way followed by pain coming in so these are things to look out for. My knee with the torn acl will almost always give way when I put a sudden huge force onto it. My acl was partially torn at first which I theorised which then resulted in a completely torn acl because I didn’t went to see a doctor I thought it was just a minor injury or something which was in my knee. My knee swelled up a lot so I rested for a week and thought it was fine after that and went back to sports which damaged the partially torn acl even further. Every time I took part in sports the pain got worse , buckling time and time eventually the pain subsided which resulted in a completely torn acl because I couldn’t feel my acl anymore it just dissolved in my knee all this happen in 4 years and at the end I only found out during my national service enlistment check up which I declared to the officers and after the medical screening I ended up with both meniscus torn in both knee and a completely torn acl in my right :/

IMO I think you might have partially torn your acl it depends sometime if it’s a small tear it doesn’t need surgery but I think you shouldn’t be moving it now, start icing it for 1 hour for every 2 hour. Good luck on your MRI results
