Physiotherapist's advice: Start using a cane again

Today I learned that the way I am walking right now (hyperflexing my left knee in to compensate for my continuing toe drop) will likely injure the ligaments in my left knee over the long term.  So, even though my walking is somewhat better, I'm going to have to go back to using a cane for any longer walking in order to train my knee not to hyperflex. Unfortunately, especially at first, my walking will look even worse while I re-train my knee.  ....*sigh*  I am again going to try the Walk-Aide system in a week or two, so if I do eventually buy it, I may then reduce my cane use at that time.
