Ivy, I totally missed that about your knee and had to go back a page to read about it after Teresa said something. Since DD is going through recovery right now, having just had her surgery last Tuesday, this is really fresh in mind for us. Like you, DD wanted to get it done ASAP. She is an old pro with crutches having used them many times in the past when she injured the same knee. She had her first physio appt yesterday and he said he wants her off them by the end of next week, and she should start putting some weight on it now (i.e. 3 days post surg). As of tonight (I just came back from helping her do her physio excercises), her knee is still about 3x bigger than normal due to all the swelling and she is still crying in pain from it - and she is a healthy teen who will probably bounce back from it faster than those of us who have a few more decades under our belts. As Teresa said, I would really plan on being out of commission more than a couple of weeks, depending on what surgery you are having. I've heard that ACL, PCL and Meniscus are actually harder to recover from than a total knee replacement but I haven't had any personal experience with any of them.
