I would do a few things:
1. really work on training...pick a system, stick with it and devote 2 15 min sessions a day to teaching her a better recall, a leave it, etc. Its partly about the learning new things, its partly about developing a "working" relationship with your dogs. I had 2 huskies and yes they are houdinis and like to run, but they are also usually pretty smart and like people so training is possible. It sounds like you have struggled with this in the past and I wonder if you have really just gotten frustrated and not stuck to it?
2. Management Always Fails. This is something I learned long ago with dogs. So when its an issue of keeping animals safe, use at least 2 management techniques: a gate behind a door, 2 closed doors, a crate in a room with a closed door, etc. Then when a door gets left unlatched etc you have a bit of time before disaster.
3. finding a way to keep her confined when you can't supervise. Give her an area, a room, etc. If she chews through kennel wire, invest in a steel kennel. Give her puzzle toys, bones etc in "her room" so its not a punishment, its a safe place. If shes arthritic get a warming bed (reflects body heat and feels good on old joints), make it a nice place.
