National Joint Registry for England, Wales and Northern Ireland: Findings from 10th Annual Report

The NJR Steering Committee launched its tenth report in late September. Data from more than 1.4 million procedures are now registered in the NJR, with considerable growth expected now that elbow and shoulder replacement data collection is underway (since April 2012) and Northern Ireland has joined the NJR (February 2013). The report also contains the second complete year of ankle replacement data.

Highlights from the report:

  • >90% of hip replacement patients had excellent, very good or good satisfaction following surgery
  • >85% of patients reported that problems were much better now vs. pre-op
