Welcome, Wendy.
I had my left TKR on March 18th. I JUST stopped walking with the cane last week. I've made two trips to the grocery store (one with the cane in my trolley, and yesterday, left it in the vehicle). The first trip went well. Yesterday I was so knackered by the time I got out of the store, I considered having one of the teen-age bagboys go get my truck so I wouldn't have to walk across the car park. (I blame the 34 Celsius heat we had yesterday).
I still use my cane for looong walks- like tomorrow, I'll be going to the university hospital in the big city because my mom's having surgery. That place is a maze of screwed-up hallways and random elevator walls... I'll NEED the cane then!
Ironically, tomorrow before we leave for Madison, I have my final physical therapy appointment!
I love this message board because it answers my questions almost before I've had a chance to ask them. I wish I'd have found it before my surgery instead of after.
