The joints are still stable and not "worn out".
If you no longer need the tripod, the threaded part can also remain on the camera. It can be removed by a latching mechanism of the tripod head and plug it back in.
Sometimes results from the necessary stance somewhat unstable design and the picture threatens to shake.
In the case you should set a small shutter lag at the camera. So waiting for the camera until the small shocks by pressing the trigger are over.
