About Me

"It's very rewarding to help patients who are limited in their physical abilities improve their activity level and quality of life."

Orthopedic Expertise

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
  • Total shoulder and reverse total shoulder replacement

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.”
