The NJRR has been collecting data on joint replacements performed in Australia since 1999. The latest, extremely comprehensive report, was able for the first time to present 10-year outcomes. Although other countries have had similar registries for longer (Sweden’s and Norway’s go back to the 1980s!), some don’t yet have one established, most notably the United States. The basic aim is to identify unusually short individual replacement survivorship in comparison to other and an overall average. The NJRR does not make comment on other aspects of outcome, such as the speed of recovery or the amount of pain or the length of incisions, etc.
A generation ago, it was common to advise that joint replacement should be delayed for as long as possible due to a high failure rate within ten years. Much has changed, including what is available to Surgeons to deal with second- and third-time surgery when it is necessary. The biggest change however, is in survivorship.
The great news is that the results from the NJRR indicate that the average survival rate for hip replacement done in Australia is 94% at ten years. This means that as an average, 94% of all hip replacements inserted continue to remain in at ten years and beyond. This is very different to the idea that they only last ten years.
The most commonly used anterior hip replacement now has three year results in our joint registry. After initial concerns from an increased revision rate due to fracture of the bone around the implants, the rate of revision is in the same range as other hip replacements. I have been performing anterior hip replacements since January 2011 and am happy to continue doing so after looking at the NJRR results.
