Evaluating shoulder joint contact patterns in osteoarthritis patients

In-vivo Evaluation of Glenohumeral Joint Contact Patterns in Osteoarthritic Glenoids

Observational Universitaire Ziekenhuizen KU Leuven · NCT06154694

This study looks at how the shoulder joint works in people with arthritis before and after they have shoulder replacement surgery to see if it can help improve their recovery.

What this trial studies

This observational study aims to assess the glenohumeral contact patterns in patients with osteoarthritic glenoids before and after total shoulder arthroplasty (TSA). It focuses on understanding the relationship between glenoid morphology, humeral head migration, and the incidence of component loosening post-surgery. By utilizing stereo radiographic EOS measurements, the study seeks to identify the mechanical factors contributing to complications in TSA. The findings could provide insights into improving surgical outcomes for patients with shoulder osteoarthritis.

Who should consider this trial

Good fit: Ideal candidates include patients with glenohumeral osteoarthritis who are scheduled for anatomic shoulder arthroplasty.

Not a fit: Patients with postoperative complications such as stiffness, pain, or instability will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved surgical techniques and outcomes for patients undergoing shoulder arthroplasty.

How similar studies have performed: While the specific approach of this study may be novel, similar studies have indicated that understanding joint mechanics can lead to improved surgical outcomes.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

OA patients group

* Patients with glenohumeral osteoarthritis planned for anatomic shoulder arthroplasty in the University Hospitals Leuven, Belgium
* Complete patient informed consent
* Pain free at the time of EOS imaging

Healthy control group

* Healthy adult volunteers with no history of shoulder pain or trauma
* Confirmation of the physician, that subject's clinical evaluation and CT scan did not show any abnormalities
* Complete informed consent

Revised TSA group

* Patients with glenohumeral osteoarthritis who received an anatomic shoulder arthroplasty at the University Hospitals Leuven within the past 30 years, and who have been revised for loosening of the glenoid component.
* At least 1 postoperative CT scan available

Exclusion Criteria:

Only patients with a functional TSA will be included, so patients with postoperative stiffness, pain, instability or pseudoparalysis will be excluded.
