Hospitalization for Total Knee Replacement Among Inpatients Aged 45 and Over: United States, 2000-2010.

In 2010, total knee replacement was the most frequently performed inpatient procedure on adults aged 45 and over. In the 11-year period from 2000 through 2010, an estimated 5.2 million total knee replacements were performed.

Record matching between the National Hospital Care Survey and the National Death Index.

Linking the National Hospital Care Survey (NHCS) with the National Death Index (NDI) provides information on the outcomes of hospitalizations and allows for analysis of individual and provider characteristics associated with in-hospital and post-discharge mortality. We test the viability of confirming hospital mortality through the linkage of preliminary 2011 NHCS data for "known dead" inpatient discharges (i.e.

Hospitalization for total hip replacement among inpatients aged 45 and over: United States, 2000-2010.

　Total hip replacement, in which both the head of the femur and its socket are replaced, is done to restore movement to hips damaged by osteoarthritis, late-stage degenerative bone and cartilage disease, or other injuries and disease (1). The number of total hip replacements is expected to increase over the next few decades (2). National Hospital Discharge Survey (NHDS) data show trends and estimates of the number and rate of total hip replacements and average length of stay among inpatients aged 45 and over.
