The AAOS has been involved in the development and dissemination of musculoskeletal outcomes instruments since the mid-1990s. The AAOS instruments were originally designed to collect patient-based data for use in clinical practices to assess the effectiveness of treatment regimens and in musculoskeletal research settings to study the clinical outcomes of treatment.
We are pleased to offer the following Instruments developed by the AAOS in collaboration with orthopaedic specialty societies and related organizations on this web site for use by individuals and organizations without copyright restrictions or registration:
