The primary endpoint is defined as survival of the implant at 10 years, which is based on removal or intended removal of at least 1-study implant component and will be determined by using the Kaplan Meier method. The safety of the system will be assessed by monitoring the frequency and incidence of adverse events. Separate analysis will be done for each arm of the study.~The secondary endpoint is represented by the performance and clinical benefits of Zimmer Biomet Shoulder Arthroplasty Systems and its instrumentation after 2 years, which will be assessed by the American Shoulder and Elbow Surgeons (ASES) shoulder score. The secondary endpoint evaluation will also assess the overall pain, functional performance, quality of life and radiographic parameters of all enrolled study subjects.
The objectives of this study are to confirm the safety, performance, and clinical benefits of Zimmer Biomet Shoulder Arthroplasty Systems and its instrumentation in primary or revision shoulder arthroplasty. These objectives will be assessed using standard scoring systems, radiographic evidence, and adverse event records. Safety of the system will be assessed by monitoring the frequency an incidence of adverse events.
