Dr. De Smet – Can both hips be operated at the same time? In severe osteoarthritis of both (bilateral) hips a bilateral procedure can be done. Both hips are operated on the same day. Our experience today has not given more problems when this is performed in healthy people. A continuous epidural catheter and more blood transfusion are needed. Cell saver is used in these conditions. Patient has to be healthy, not obese, and the hip condition itself does not have to be severe.
