I tore my ACL when I was younger and continued to play for a few years with the tear before if fully came apart. It is something you can play with (after the initial swelling goes down), but it won't be as stable and you will have constant pain and discomfort, that I just got use to. Brace it well, some pain meds before, ice after use, but eventually it will get worse, so get it fixed. New surgeries have them back up and going in weeks and playing competitive in 6-12 months if not sooner.
