A WashU study comparing two modern approaches to total knee replacement – cemented and cementless implants – was recently named one of the top orthopedic papers of 2025 by The Journal of Bone & Joint Surgery.

Our research team followed patients for at least five years and achieved an exceptional follow-up rate, helping provide strong evidence about how these implants perform over time. The study found that modern cementless knee replacements performed just as well as traditional cemented implants at mid-term follow-up, with excellent durability and function, and a higher percentage of patients who reported extremely or very satisfied with their overall function.

"The move to cementless total knee arthroplasty is probably the most significant change in the arthroplasty world this decade, and this study is tribute to our research team and the impact on care," shared Robert Barrack, MD, co-author of the paper.

This weekend's Missouri State Orthopaedic Association annual meeting will focus on shared learning, practical case discussions, and connection among orthopedic surgeons who understand the privilege of caring for Missourians.

David Brogan, MD, MSc, explains, "Ensuring patient access to high-quality orthopedic care remains a major concern, especially as policy changes and funding cuts continue to impact care delivery – particularly in rural Missouri. These decisions have real consequences for patients and communities across our state.”

"I hope attendees leave feeling more connected — to each other and to the work we’re doing together for orthopedic surgeons and patients across Missouri."

Did you know the NFL recently banned smelling salts (ammonia inhalants) from being given to players?

Smelling salts have been used for centuries, but emerging research has prompted a closer look at their safety in sports. New research led by Matthew Matava, MD, Chair of the NFL Research & Innovation Committee, helped inform the league’s decision to prioritize player health.

Once used on sidelines as a quick way to “wake up” athletes, smelling salts are now being reexamined due to their effects on performance and the potential neurologic risks they may pose – particularly following a suspected head injury.

On National Girls & Women in Sports Day, we celebrate the achievements of female athletes, coaches, leaders and physicians dedicated to this population. The Female Athlete Program supports girls and women in their unique needs.

Katherine Caldwell, MD, Director of the Female Athlete Program shares one of the biggest factors in training for women – STRESS. She shares, "Last week, I hit a lighter squat than usual – not because I got weaker, but because I was stressed and under-recovered. This week, I was better rested, less stressed, and a heavier weight moved way easier."

The Female Athlete Program is treating the whole athlete, "Our goal is to provide specialized care tailed for female biomechanics, hormone fluctuations, and unique training demands."
