Yes, but it depends on regaining your knee flex to a good level. Sitting cross legged, I can't get my knees down to the floor as far as before, so heel on opposite knee won't go, and you have to be careful of not putting too much twist pressure on the knee. But that doesn't mean you can't adapt positions to what you can manage.

Something like child's position with both knees on the floor has become more comfortable with time. I used to need an extra pillow under the knees, but now I am fine with just the living room carpet.
