Dr Chan is one of the best in the business, he does what’s right for you and a super person. I am 6’2” and 270 lbs it took me a little more than a year to convince myself to get it replaced, don’t wait the difference is huge. After surgery I used the walker 1-2 days then the cane for 4 days and was walking good after 2-3 weeks, it’s 6 weeks now and it feels very good things I have not been able to do in years. Dr Chan is really good so don’t wait.
