What this trial studies

This observational study focuses on the clinical and radiological outcomes of the Medacta Shoulder System in patients with various shoulder conditions. It aims to gather data on the effectiveness and safety of this shoulder implant in real-world settings following its market release. Patients over 18 years old with specific shoulder diagnoses will be monitored for their recovery and overall satisfaction post-surgery. The study will include a diverse range of shoulder-related conditions to assess the implant's performance across different patient profiles.

Why it matters
