Download the MsTR 2025 Annual Report

The AAOS Musculoskeletal Tumor Registry (MsTR) released its inaugural Annual Report, marking the first comprehensive national analysis of real-world, physician-entered clinical data in musculoskeletal oncology. The 2025 report captures 1,189 procedures submitted between 2016 and 2025 across nine participating institutions, reflecting a 67% growth in the dataset and an ongoing rise in data submissions year over year.

The MsTR 2025 Annual Report provides an in-depth look at patient characteristics, tumor pathology, treatment patterns, device use, and outcomes within bone and soft-tissue sarcoma care. By offering standardized clinical information across multiple institutions, the report helps orthopaedic surgeons, researchers, and health systems better understand variations in practice, monitor device performance, and identify opportunities to strengthen musculoskeletal oncology care.
