The American Joint Replacement Registry (AJRR), the largest hip and knee replacement registry worldwide, conducted a study analyzing the correlation between hospital size, the reason for revision (or re-do) surgery, and the hospital where the total joint arthroplasty (TJA) revision surgery is performed. The link between these three factors has not been studied extensively until now. A poster on the study's findings was presented at the 2018 American Academy of Orthopaedic Surgeons (AAOS) Annual Meeting in March. The poster, titled, "Is There a Correlation Between Hospital Size and Revision Indication and Where TJA Revision Surgery is Performed?" can be seen above.
