Dr. Peter Millett of The Steadman Clinic Helps Lead NIH-Funded Study on AC Joint Repair

Vail, CO – September 16, 2025 – The Steadman Philippon Research Institute (SPRI), in partnership with the University of Texas Health Science Center at Houston (UTHealth), has launched a groundbreaking five-year, NIH-funded clinical study to evaluate and compare three advanced surgical techniques for acromioclavicular (AC) joint repair.

The study will be conducted at SPRI's world-class research campus in Vail, Colorado, and at UTHealth in Houston, with the goal of identifying which technique delivers the best outcomes for restoring shoulder function and ensuring long-term shoulder health.

Two of the three surgical methods being studied were previously published in peer-reviewed journals by Peter Millett, MD, renowned orthopedic shoulder surgeon at The Steadman Clinic, and co-investigator Matthew Provencher, MD. Their pioneering work has shaped modern approaches to AC joint reconstruction, and this trial aims to validate those techniques on a larger scale.

Researchers will monitor patients at six months and one year post-surgery, evaluating shoulder mobility, cartilage health, and the recovery of tendons and ligaments. By analyzing these outcomes, the team hopes to establish the most effective treatment protocols for athletes, active patients, and individuals suffering from AC joint injuries.

"This study represents an important step forward in shoulder surgery," said Dr. Peter Millett of The Steadman Clinic. "Our goal is to use rigorous, NIH-funded research to give patients the best chance at full recovery, improved performance, and long-term joint health."

Enrollment for the study has officially begun, with results expected to help shape future standards of care in sports medicine and orthopedic surgery.

Dr. Millett and his team did a SLAP tear repair and bicep tenodesis on my left shoulder. I use my arms as an artist, and love to swim in the ocean, surf, paddle, and telemark ski. So regaining full use of my shoulder and keeping my bicep attached was very important to me. Now, over two years later, my shoulder has the equivalent range of motion as my other arm and as before the injury, and no pain. After the first three months it felt so good and was so strong that - to my horror - I completely forgot my six-month follow-up.

Not only did Dr. Millett and his team make my arm as good as new, but having had the experience of such kindness and expertise throughout the process of surgery and recovery is like an added shoulder superpower.

Thank you Rita, Brooke, Jason, Sarah, Camille, Olivia, Dr. Millett and everyone! And see you soon when my husband comes in for his knee...

Flawless procedure, Easy recovery

Dr. Millet's repaired my knee and tibia, following a botched operation by a different surgeon. That procedure was virtually pain free and I was weight bearing within a few days. That was 18 years ago and the knee is still strong. A few years after the knee incident, Dr Millet repaired my shoulder. My insurance company approved me for 3 months of disability following that surgery. I was off pain medication in 2 days and had 90% range of motion within a week. I withdrew my disability claim and returned to work within two weeks of surgery. I’m not a famous athlete—just a regular guy. Nonetheless, I was treated like an NFL at the Steadman clinic. Most notable was the time for recovery. Other surgeons perform their hour-long task in the OR and don’t involve themselves in the other functions. Peter and his team manages the entire process from diagnosis, anesthesia, nursing care, and therapy. He takes a holistic approach to patient care and doesn’t skip any steps.

Saved My Life

I went to Dr. Millett after 7 knee surgeries (6 on my right and 1 on my left) and had seen 11 different surgeons who all refused to remove femur metal from my right leg. I am highly allergic to metal and the chronic pain was leaving me bedridden for 3.5wks out of a month. He personally wrote me back on my inquiry, listened to my concerns, scheduled my surgery within a week (due to insurance issues) and personally followed up with my recovery. The level of patient care from Dr. Millett and his ENTIRE team is above any care I have ever received in my 20 years of dealing with orthopedic surgeons. There are not enough words to describe the level of care, dedication and professionalism you receive from Dr. Millett and his staff.
My only disappointment is that I did not find him sooner!!!
