What is this trial?

Researchers want to understand how shoulder arthritis changes the way your shoulder joint moves and distributes pressure. By studying patients before and after shoulder replacement surgery, as well as healthy volunteers, they hope to learn why some shoulder replacements fail over time and how to improve future surgeries.

Shoulder replacement surgery helps many people with arthritis, but some implants become loose and fail years after surgery. Doctors don't yet fully understand why this happens—it may be related to how the joint moves and where pressure is placed on the artificial joint. This study aims to fill that gap.

Do you qualify?

You likely qualify if…

you have been diagnosed with shoulder osteoarthritis and are scheduled for shoulder replacement surgery at the University Hospitals Leuven in Belgium
you are a healthy adult volunteer with no history of shoulder pain or injury
you had shoulder replacement surgery at the University Hospitals Leuven in the past 30 years and required a revision surgery due to loosening of the implant
you are willing to give full informed consent to participate
you are pain-free at the time of imaging (for arthritis patients)

You likely don't qualify if…

you have had shoulder stiffness, pain, instability, or paralysis after shoulder replacement surgery
you have a history of significant shoulder trauma or injury
you do not have at least one postoperative scan available (for revision surgery patients)

What participation looks like

If you join this study, you will have imaging scans (such as CT scans) of your shoulder taken while in specific positions. Arthritis patients will have scans before and after their surgery. Healthy volunteers will have one set of scans for comparison. The visits are relatively straightforward—mainly involving the imaging appointments—with no medication or invasive procedures required.
