Personalized approach to shoulder joint replacement
Official title: Multicenter Randomised Study of Personalized Instrument in Total Shoulder Arthroplasty The P.I.T.S.A. Study
Run by Université de Montréal · NCT03839758 · Data updated 2026-11-12
This study is testing if using a personalized guide based on CT scans during shoulder replacement surgery can help people with shoulder arthritis recover better than using standard guides.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are patients with shoulder osteoarthritis or avascular necrosis scheduled for elective primary total shoulder arthroplasty.
✕Probably not a fit
Patients with previous shoulder arthroplasty, inflammatory arthritis, or those who cannot commit to a two-year follow-up may not benefit from this study.

What this trial studies
This study evaluates the effectiveness of a personalized glenoid guide in total shoulder arthroplasty for patients with shoulder arthritis. Participants will be randomized into two groups: one using a patient-specific guide based on preoperative CT scans and the other using a standard method with generic guides. The study aims to improve the precision of glenoid component implantation, which is crucial for reducing complications such as loosening and instability. Preoperative assessments will include demographic data, range of motion, quality of life, and functional status.
Why it matters
Potential benefit: If successful, this approach could lead to improved surgical outcomes and reduced complications for patients undergoing shoulder replacement surgery.
How similar studies have gone: While the use of personalized guides in orthopedic surgery is gaining traction, this specific approach in total shoulder arthroplasty is relatively novel and has not been extensively tested in prior studies.
