Table 1. Number of data entry records (i.e. hip and knee registrations) in the LROI
Figure 1. Number of primary total hip arthroplasties (THA) and revision hip arthroplasties (left panel) and number of primary knee arthroplasties and revision knee arthroplasties (right panel) in 2007–2013 registered in the LROI. The period 2007–2009 was the run-in phase of the LROI and therefore the registration is known to be incomplete for those years.

Figure 2. Number of procedures performed and registered in the LROI per hospital for primary total hip arthroplasty (THA), hip revision arthroplasty, primary knee arthroplasty, and knee revision arthroplasty. * No data available from the hospital information system for comparison. Only hospitals which performed primary, revision, hip or knee arthroplasty are shown.
