Hello my name is***** would start by draining the oil after you filled it back up and make sure there is not shiny metallic flakes in the oil if you do not see any flakes I would just refill the engine add a oil stabilizer like the LUCAS brand or any oil stabilizer from an auto parts store will do you should be ok you could check oil pressure if you have a gauge but since you stopped the engine when it started knocking you should not have damaged any components
