Evidence-based medicine integrates research findings, clinical expertise, and patient values to provide the highest quality patient care. An orthopaedic outcomes database can assist surgeons in assessing associations between surgical procedures, function, survivorship, complication rates, patient satisfaction, and quality of life as guidance for practice. Outcomes are used to validate techniques or procedures, to benchmark best practices, and to identify areas requiring more clinical research. Tracking the success and failure rates of implants and surgical procedures is important. An outcomes database allows for short-term, midterm, and long-term prospective follow-up studies of specific cohorts and also facilitates studies that are retrospective in design.
