TL;DR: These large projected increases in demand for total hip and knee arthroplasties provide a quantitative basis for future policy decisions related to the numbers of orthopaedic surgeons needed to perform these procedures and the deployment of appropriate resources to serve this need.

TL;DR: Hip instability and mechanical loosening are the most common indications for revision total hip arthroplasty in the United States, and this information will be valuable in directing future research, implant design, and clinical decision-making.

TL;DR: The number and prevalence of primary hip and knee replacements increased substantially in the United States between 1990 and 2002, but the trend was considerably more pronounced for primary total knee arthroplasty.

TL;DR: In this paper, the authors developed projections for demand of total joint replacement (TJR) surgery in young patients (< 65 years old) in the United States, using the Nationwide Inpatient Sample (NIS) between 1993 and 2006.

TL;DR: Revision TKA procedures were most commonly performed in large, urban, nonteaching hospitals in Medicare patients ages 65 to 74, and the average length of hospital stay was 5.1 days, 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.
