Any suggestions?

You might try installing a larger diameter wood screw thread/threaded bolt into the leg. If that doesn’t work try an epoxy glue.

I would use epoxy, rough up the inside of the hole, and if you have a dremel/die grinder i would try to taper the hole so that the diameter is larger at the bottom of the hole. Epoxy is great stuff, but it’s much more of a mechanical bond than a chemical bond, the surface needs to be rough and with the taper it should hold really well.

I’m nervous about the epoxy clogging the threads of the inserts.

If the other legs are sound, we can assume the existing system is adequate.

So, another solution would be to plug the holes and rebore them for the threaded inserts.

I’d enlarge the holes and it would be best if you could plug them not with dowels but with plugs, so the grain will give more bite to the inserts. The plugs could be epoxied in or yellow glued.

Just put bolts in the threaded inserts when you epoxy them in place, any epoxy in the threads won’t hold onto the bolt, it will just thread right out.

I cast my vote for drilling them out oversize and gluing in plugs, re-drill to the correct size and epoxy in the inserts.
If you are worried about epoxy fouling the threads put vasoline on the bolt, thread them into the insert and then epoxy them in place.
