Understanding the cause of failure and type of revision total knee arthroplasty (TKA) procedures performed in the United States is essential in guiding research, implant design, and clinical decision making in TKA. We assessed the causes of failure and specific types of revision TKA procedures performed in the United States using newly implemented ICD-9-CM diagnosis and procedure codes related to revision TKA data from the Nationwide Inpatient Sample (NIS) database. Clinical, demographic, and economic data were reviewed and analyzed from 60,355 revision TKA procedures performed in the United States between October 1, 2005 and December 31, 2006. The most common causes of revision TKA were infection (25.2%) and implant loosening (16.1%), and the most common type of revision TKA procedure reported was all component revision (35.2%). Revision TKA procedures were most commonly performed in large, urban, nonteaching hospitals in Medicare patients ages 65 to 74. The average length of hospital stay (LOS) for all revision TKA procedures was 5.1 days, and the average total charges were $49,360. However, average LOS, average charges, and procedure frequencies varied considerably by census region, hospital type, and procedure performed.Level of Evidence: Level II, economic and decision analysis.

• Economic burden of periprosthetic joint infection in the United States. (2012, background): “Periprosthetic joint infection (PJI) is the most challenging complication associated with total joint arthroplasty in the 21st century [1,2] and, from the perspective of patients, surgeons, hospitals, and the health care system, perhaps the most grievous [3-5].”
• Why are total knee arthroplasties failing today--has anything changed after 10 years? (2014, background): “Recent studies have further analyzed failure mechanisms of primary TKA highlighting not only the role of PJI and aseptic loosening in failure, but also how such failure mechanisms may affect revision surgery outcomes [7,8].”
