I've had knee surgery, I'm looking like worn out Raggedy Ann doll these days, and it isn't bad if you have the microscopic type. They even showed me a video of the inside of my knee after. Trying to use crutches was a real bitch and I didn't listen to them and support my weight with my arms instead of my underarms and ended up with very sore underarms so be sure she uses her hands and arms to support her weight when walking with the crutches.
