sorry, i notice its your left knee, in which case you are fucked. if it was the right one you'd be fine. so wrap a tourniquet round your thigh and take a bread knife to your leg. its best to have a phone handy so if you feel yourself passing out you can dial an ambulance, there is a bonus to this as the nhs can make the scar site look pretty.
or the simple rest ice compression elevation for a couple of days and see how it feels
there are specialist knee physiotherapists
