The AAOS Musculoskeletal Tumor Registry (MsTR) is part of the AAOS family of registries, a program that aims to encompass all the musculoskeletal and anatomical areas for orthopaedics. The MsTR’s purpose is to provide a centralized record of patient, tumor, treatment, and outcomes data on musculoskeletal neoplasia in the pelvis, spine, and extremities. The data will allow for the investigation into the natural history of the disease, risk factors, quality and delivery of care, oncologic and reconstructive outcomes, prognosis, function, and patient quality-of-life.

The data presented in this report is derived from 1,290 sarcoma procedures performed between January 1, 2016, and September 17, 2026. This represents an 8.5% increase compared to last year's report. Data contributions came from nine institutions.
