Osteoarthritis Clinical Trial Network Research

Members of the OA Clinical Trial Network collaboratively work on a variety of projects intended to advance OA clinical research.

3D Joint Space Width from Weight Bearing CT as an Imaging Biomarker of PTOA, University of Iowa

This project aims to establish affordable imaging biomarkers using weight-bearing CT in order to detect PTOA earlier.  Patients with an intra-articular fracture at high risk for developing PTOA will be studied at three sites (University of Iowa, University of Utah, and University of Washington).  3D joint space width maps and joint alignment will be computed from low-dose weightbearing CT studies obtained after surgical fracture reduction in a newly enrolled cohort of patients, as well as in a prior cohort, to determine how early changes correlate with later PTOA development.

Injection after Arthroscopic Partial Meniscectomy 

This project aims to execute a randomized controlled trial of long-acting triamcinolone (Zilretta, Flexion) versus placebo administered in the operating room after arthroscopic partial meniscectomy (APM).  The results of the study will provide important information about the role of synovitis and inflammation in the patient reported outcome after surgery, as well as determine whether the injection can improve the outcome.

Biomechanical Changes Following ACL Injury that Influence Post-Traumatic Osteoarthritis 

This project aims to identify biomechanical targets that can be modified to mitigate the risk of PTOA onset following anterior cruciate ligament reconstruction (ACLR).  The proposal seeks to determine the early time course of relevant biomechanical changes post-ACLR as well as the association between biomechanics and patient-reported outcomes.  Measures of biomechanical loading (quadriceps strength assessment, walking gait mechanics analysis, steps-per-day via wearable device) and joint tissue metabolism (serum chemokine analysis), patient reported outcomes (PROs), and preoperative MRI will be selectively collected at the various time gates.

More About Volunteering

Live Yes! INSIGHTS


Give Just 10 Minutes.

Tell us what matters most to you. Change the future of arthritis.

By taking part in the Live Yes! INSIGHTS assessment, you’ll be among those changing lives today and changing the future of arthritis, for yourself and for 54 million others. And all it takes is just 10 minutes.

Your shared experiences will help:

- Lead to more effective treatments and outcomes
- Develop programs to meet the needs of you and your community
- Shape a powerful agenda that fights for you

Now is the time to make your voice count, for yourself and the entire arthritis community. 

Currently this program is for the adult arthritis community.  Since the needs of the juvenile arthritis (JA) community are unique, we are currently working with experts to develop a customized experience for JA families. 

How are you changing the future?

By sharing your experience, you’re showing decision-makers the realities of living with arthritis, paving the way for change. You’re helping break down barriers to care, inform research and create resources that make a difference in people’s lives, including your own.
