About Me

Stephen Johnstone, MD, is an Assistant Professor of Orthopaedic Surgery at the Icahn School of Medicine at Mount Sinai. He specializes in hip and knee joint replacement. He received his medical degree from the Joan and Sanford I. Weill Medical College of Cornell University and went on to complete his orthopedic residency at the top ranked University of Pittsburgh Medical Center. Subsequently, he completed a fellowship in adult joint reconstruction at the highly regarded Hip and Knee Center of the New York Presbyterian Hospital, Columbia University Medical Center where he studied advanced orthopedic surgical techniques.

In addition to his clinical focus on hip and knee replacements, Dr. Johnstone treats a range of orthopedic conditions including adult fractures, shoulder replacements, rotator cuff tear and meniscal tears. He provides compassionate and customized care to patients and believes that patient education plays a key role in achieving optimal clinical results. When patients understand their orthopedic conditions, they can best partner with him in their treatment plans. In addition, he aims to see patients as a whole, understanding that their pain is only one part of who they are as people. He values the relationships he forms with his patients and the transformative role he plays in their lives. Dr. Johnstone finds it most rewarding to improve a patient’s well-being through his ability to replace pain and limitation with function, mobility, and independence.
