Stuttering when making a movement command

I don't know if anyone else has had a problem like this, I've tried looking it up and to no avail. When I make a movement command, my champion will tend to studder in place, sometimes even teleporting slightly ahead, making movements unclear, choppy, and hard to play properly. I'm wondering if there's a fix for it, I've tried re-downloading the client, that worked for a little while, but eventually it came back again. I don't believe it has anything to do with my ping as it's always been around 60 and beforehand I never had this problem. Its become much of a nuisance as of late and I hope someone has a solution.
