About Me

Dr. Seth Christensen brings expert surgical skill and deep orthopedic knowledge to Avera Orthopedics – Aberdeen 8th Avenue, where surgical knee and hip replacements are the primary focus of his sub-specialization.

As a board-certified orthopedic medicine specialist, Dr. Christensen understands how the pain that goes with arthritic joint conditions can limit quality of life and lead to a lifestyle with less activity – and less joy.

That’s why his focus is on patients who want to spend time with children and grandchildren, continue a career or travel without the impediments that come with joint pain. He is fellowship-trained in the use of robotic surgical techniques which can help ensure your joint-replacement surgery is a success and that recovery time can be reduced.

No matter what orthopedic issues or injuries might bother you, Dr. Christensen can provide the quality, patient-focused care that can help you make your move toward a happier, more-active life.

Active Lifestyle

While not seeing patients, Dr. Christensen enjoys time with family, riding bicycles, taking hikes and walks and exploring. He’s also an avid reader and a gourmet in the kitchen.

Dr. Christensen is clearly a huge asset at Avera for his knowledge and skill, and just as much for his consideration of his patients. He has been patient and very kind in every interaction we've had.
