is it normal for your knee replacement to snap when you put your leg into a frog leg type position?

Knee snapping: Yes. At the extremes of the range of joint motion, sounds like "snapping" are more likely to occur in both normal and artificial joints. The frog-legged position puts your knees through a relatively extreme position.
