About Me

Count on Patrick O’Brien, MD, for expert orthopedic care and advanced orthopedic services, including:

  • Arthroscopic surgery for the shoulder, knee, elbow and hip
  • Arthroscopic rotator cuff repair and labrum surgery
  • Knee ligament repair and reconstruction (ACL) and meniscus surgery
  • Sports medicine
  • Hip scopes and hip labral repairs

Dr. O’Brien has extensive training in orthopedic surgery, including minimally invasive procedures, and sports medicine. When possible, he offers patients conservative, non-operative treatment first before considering surgery.

“My hope is that patients will feel like I did everything I could to help them,” he says. “It’s important to listen to their concerns and involve them in their care.”

Active Lifestyle

Dr. O’Brien is excited to serve his hometown community of Sioux Falls. As parents of two young children, he and his wife stay active by enjoying outdoor activities in the Sioux Falls parks and bike trails.

“Staying active is a great way to maintain your joint health. Prevention is easier than treatment. That’s why I recommend daily exercise, such as walking. Older adults can also improve their bone health by taking calcium and vitamin D supplements.”

Dr O'Brien and his team have been a pleasure to work with. He did my hip surgery in December and has been very understanding of my struggles with recovery. Would recommend Avera to anyone.

The people who worked in the room with me were very professional and friendly. They didn't make me feel rushed. When I brought up a concern of having two doses of shot at the same time.Andmy possible allergic reaction. She stopped right there to talk to Dr. O'Brien. I felt awkward bringing it up but both people reassured me that it was a good idea to get it checked out by the doctor before proceeding. Very kind and professional staff. Thank you so much!

Excellent experience as alway with my Avera family.

My mom lives in Illinois. She fell and broke her shoulder and is staying with me in SD, so I can care for her. It was very complicated to try and continue with her ortho doctor in Illinois. Dr. O'Brien and the staff made it easy and uncomplicated. It was a breath of fresh air. Our visit was organized and people were all very kind and accommodating. Thank you!

I would have given them a 10 out of 10. But we did not have all of the information we needed to find the problem with my hip. If not for that hick-up it would have been perfect score.
