My Tendon On My Left Hand Pinky Slides Off My

My tendon on my left hand pinky slides off my knuckle every time I close my fist. I used to have a habit of clicking the tendon of my pinky for a few years. I've been to many hand specialists and doctors about it an no one seems to know what to do to stop this. Even though i can stretch my pinky out it's now in a almost consistent bent and triggerd state. Any ideas?
