mack's surgeon gave the right advice - "Experiment and see what works best for you." And very likely as the leg gets a bit better you'll find yourself using a different technique.   

If you carry a walking stick and you haven't got a bad leg at all - for example on a country walk - it's a different technique again - I tend to swing it more and only touch it on the ground every few paces, or just carry it. A good stick is a great companion.
