About Dr. Trenhaile …

As an innovator with extensive knowledge in shoulder, knee and elbow injuries, Dr. Trenhaile has earned a renowned national and international reputation among his peers.  He is frequently sought to give lectures globally at conferences and medical summits on issues related to orthopedic procedures and sports injury management.  Since 2009, groups of surgeons from the United States, Europe, and Asia have traveled to Rockford, Illinois to observe Dr. Trenhaile’s practice and learn his advanced surgical techniques.  The state-of-the-art facilities at OrthoIllinois, including a dedicated cadaver lab and OrthoIllinois Surgery Center, enable him to host a variety of educational events and surgical courses.

Dr. Trenhaile serves on the AANA Copernicus Initiative Committee for Shoulder Evaluation Development and recently served as an expert surgeon for determining the benchmark of protocol for ACL Knee Reconstruction.  He holds a number of patents for surgical instruments and techniques that are used throughout the world to allow surgeons to perform minimally invasive arthroscopic orthopedic procedures that were previous “open techniques.”

Currently Dr. Trenhaile serves as Clinical Assistant Professor at the University of Illinois College of Medicine: Rockford, and Assistant Professor at Rush University Medical Center Medical Collage in Chicago, Il.  He is a member of many prestigious national and international societies and associations, including the American Academy of Orthopedic Surgeons, the American Orthopaedic Society for Sports Medicine, the Arthroscopic Association of North America, and most recently the American Shoulder and Elbow Surgeons, whose invitation-only membership is limited to fewer than 550 physicians world-wide.

Here's what my patients are saying:

Dr. Trenhaile and the OrthoIllinois surgical staff rock.


48 hours after my knee surgery, and I feel like I can go back to work already. Thanks, Dr. Trenhaile!

First I needed care for my injured right rotator cuff. Then it was a torn right meniscus in my knee. Dr. Trenhaile did a great job with both.
