This is Chris (Lisa's husband). She went in for her replacement at seven this morning. I have just been informed by Dr. Bolling that the surgery is complete and went very well. She is currently resting in ICU and should be up soon. I would like to thank all of you on this site who have offered support and advice to her as we travelled this path. I know it has helped ease many of her fears. I will update later and soon enough she will be on here to tell her own story.
