Patients scheduling elective total joint replacement surgery are eligible to participate.~The Aims of the registry are as follows:~Aim 1. Establish a national registry of diverse patients of orthopedic surgeons representing all regions of the country and varied hospital and surgeon practice settings (e.g., urban/rural, low and high volume) to ensure that registry analyses and research reflect typical clinical practice thereby providing optimal guidance for patients, clinicians, and national healthcare policymakers. Collect pre-operative and post-operative patient reported outcomes (PROs) for pain and function.~Pre-surgery data. Patients will complete a set of computer-based clinical and behavioral health questions prior to surgery. A paper option is available as well. Data collected include demographics, medical and musculoskeletal comorbidities, pain and function measures.~6 month survey. Patients will receive an invitation to complete the 6 month survey either on the computer at home or on paper. This survey includes the symptom assessment and a screening survey for complications.~12 month and subsequent annual surveys. The 6 month survey will be repeated at 12 months and annually thereafter. In addition, the patient's contact information will be updated.~Oxford Knee Scale, EQ-5D Survey and Satisfaction Questions may be added to a subset of questionnaires.~Using the data collected to date from more than 25,000 patients, the investigators have identified national norms for pre-op and post-op pain and function as well as a Risk-adjustment model for outcomes.~Aim 2: Develop new and transformative comparative effectiveness tools useful to both clinical practice and healthcare policy.~Aim 3. Broadly disseminate surveillance reports for adverse events, such as implant revision, hip dislocation, knee manipulation, and identify important variation to inform quality improvement priorities.
