Researchers are collecting and evaluating long-term data on clinical and radiographic outcomes to better understand the safety and performance of shoulder arthroplasty over time. This study includes people with various shoulder conditions such as osteoarthritis, osteonecrosis, rotator cuff tears, rheumatoid arthritis, fractures, and infections. The trial will follow participants for at least 10 years, with no early limit on follow-up duration. The study includes patients who are either scheduled for shoulder arthroplasty or have already undergone the procedure. Participants must be skeletally mature and expected to survive at least two years beyond surgery. The study is open-label and multi-center, involving both retrospective and prospective data collection. There are no specific interventions or treatments being compared, as the focus is on observing outcomes after shoulder arthroplasty. Participants will undergo assessments including clinical and radiographic evaluations at an average of once per year throughout the study. Outcome measures include the Constant score, ASES (American Shoulder and Elbow Surgeons) score, Oxford Score (optional in the UK), TESS, and MSTS scores related to pre-operative conditions. Researchers will monitor participants for safety and implant performance during the long-term follow-up, which can last a minimum of 10 years.
