Although it seems like yesterday, it has been a year since you performed my hip replacement surgery. I went from excruciating pain every time I got in or out of the car or bed to being absolutely pain free since my surgery. Thank you so much for giving me back my life! I am so grateful to you and your team. I’ve told everyone that if they should ever need a hip replacement, Dr. Knowlan is the best. When my husband Steve and I met with Dr. Hartleben, we told him we wanted the best surgeon. He didn’t hesitate to recommend you. I even got to go to a hospital close to home with the most wonderful caring staff, I couldn’t be happier.
