Overview

I am an orthopaedic physician and work in adult reconstructive orthopaedics, predominantly with hip- and knee-replacement surgeries. I also help manage revision surgeries and take care of people with infections or fractures around their implants. I am interested in the whole continuum of care for arthritis and not just the surgical treatment of it. Even though I specialize in surgery, not everyone needs that treatment, and as an orthopaedic doctor, my role is to help direct the whole process. The care around revision surgeries at other centers is tertiary and many times not at the same place, but here at Duke we treat patients every step of the way at the same practice and have access to the latest treatments.

Dr. Jiranek is rated as an Experienced provider by MediFind in the treatment of Malnutrition. His top areas of expertise are Osteoarthritis, Infectious Arthritis, Septic Arthritis, Knee Replacement, and Hip Replacement.

His clinical research consists of co-authoring 143 peer reviewed articles and participating in 3 clinical trials. MediFind looks at clinical research from the past 15 years. In particular, he has co-authored 2 articles in the study of Malnutrition.

The impact I have on my patients is what I enjoy most about being a weight loss surgeon. It is amazing that we can do an operation that not only helps a patient lose weight, but also fixes their diabetes, high blood pressure, and cholesterol, along with giving them a better quality of life. There are a lot of options these days for people who are considering weight loss surgery. It’s important for patients to take into account each institution and what resources they have available. Duke is fully equipped to take care of complex cases in a safe manner. We have a multi-institutional team that’s been around the Triangle the longest and has the most experience. Almost every patient comes back after surgery and we see some of their previous medical conditions go away. That’s a good definition of success. Dr. Portenier is rated as a Distinguished provider by MediFind in the treatment of Malnutrition. His top areas of expertise are Obesity, Hernia, Short Bowel Syndrome, Gastric Bypass, and Sleeve Gastrectomy.

I am a fellowship-trained, board-certified orthopaedic surgeon specializing in hip and knee replacement and reconstruction. My practice includes nonsurgical and surgical care for osteoarthritis, rheumatoid arthritis (and other autoimmune arthritis), and avascular necrosis. I offer partial and total joint replacement, using minimally invasive techniques and cutting-edge methods such as robotic and computer navigation, 3D anatomical modeling, direct anterior total hip arthroplasty, and rapid postoperative recovery protocols with an option for outpatient surgery. My comprehensive approach includes medications, injections, physical therapy protocols, and other interventions aimed at avoiding surgery. I also evaluate and perform revision arthroplasty for failed joint replacements and specialized reconstructions for less common conditions. Dr. Schwartz is rated as an Advanced provider by MediFind in the treatment of Malnutrition. His top areas of expertise are Infectious Arthritis, Septic Arthritis, Osteoarthritis, Hip Replacement, and Knee Replacement.
