If you have a loose door hinge that has stripped the doorframe, it is still fixable. You can use a golf tee to solve your problem and fill in the over stretched hole.
Take the door off the hinges and squirt carpenter's glue into the hole. Now, insert the golf tee and tap it until it is tightly in the open space. Then, cut off the golf tee flush with the doorframe (you can use a utility knife). Allow the glue to dry and affix the hinge back on the door by inserting the screw into the golf tee.
You can also just fix one hinge at a time so you don't have to remove the door and totally rehang it.
