Peter S. Johnston, M.D.

Dr. Peter Johnston joined Southern Maryland Orthopaedics in September 2011. He was born and raised in Bloomfield Hills, Michigan. He received his Bachelors of Science degree in Neurosciences at the University of Michigan in Ann Arbor, MI. He completed his medical training at Wayne State University in Detroit, MI where he graduated with honors.

Dr. Johnston completed his orthopaedic internship at the Detroit Medical Center/Wayne State University School of Medicine and then moved to Chapel Hill, NC where he completed his formal orthopaedic surgery training at the University of North Carolina. At the University of North Carolina, he received the Resident of the Year Award as well as the William C. Patton Chief Resident distinction for excellence in teaching as nominated by his colleagues. He participated in sports coverage and care of the Division I athletes at UNC and the local high schools.

After completing his residency, Dr. Johnston spent a year as a fellow at the prestigious Rothman Institute at Thomas Jefferson University in Philadelphia, PA sub-specializing in shoulder and elbow surgery. While at the Rothman Institute, he focused on treatment of complex shoulder and elbow conditions including joint replacement for arthritis, instability, fractures, rotator cuff and labral tears, and triceps and biceps tendon tears.

By joining Southern Maryland Orthopaedics, Dr. Johnston brings a strong background in general orthopaedics. He trained with world leaders in all aspects of musculoskeletal care at the University of North Carolina. He focuses on complex surgery of shoulder and elbow conditions including: joint replacement for arthritis and fractures, reverse total shoulder replacement for cuff tear arthropathy, fracture care, tendon tears, and instability. He offers arthroscopic methods for management of arthritis, instability, joint contracture, rotator cuff and labral tears. He also focuses on sports injuries to the knee, shoulder and elbow.

He continues to pursue his research interests with recent peer reviewed publications, book chapters and presentations on the management of proximal humerus fractures with hemiarthroplasty versus reverse shoulder arthroplasty, treatment of massive rotator cuff tears and the management of shoulder arthritis in younger patients. Southern Maryland Orthopaedics’ affiliation with the Medstar Health System and Georgetown University Orthopaedic Surgery will provide Dr. Johnston the ability to teach residents and stay involved in academic pursuits.

As a new member of the community, Dr. Johnston brings with him his wife, Tiffani and daughter Matti Jane. He aims to become active with sports coverage for high school athletics and activities to give back to the community. His interests outside of work include family, golf, fishing, hunting, and skiing.
