DePuy Synthes announced in June the new ATTUNE® Knee implant survivorship data based on an Implant Summary Report obtained from the National Joint Registry for England, Wales, Northern Ireland and the Isle of Man (NJR).
The independent analysis of 10,605 ATTUNE Knee implantations showed that the cumulative revision rate for the ATTUNE Knee is 1.3 per cent at four years (98.7 per cent implant survivorship at four years), compares favourably to the 1.9 per cent cumulative revision rate (98.1 per cent implant survivorship at four years) for the overall class of total knee replacement. 
Of the 10,605 ATTUNE Knees included in the analysis from the NJR, 46 required revision. Based on a separate analysis, the report concluded that 63 ATTUNE Knee revisions would be expected at four years – a difference that was statistically significant (p<0.05).  The expected number of ATTUNE Knee revisions was calculated by the NJR based on duration of implantation, age group, gender and indications.
DePuy Synthes announced the four-year data at EFORT in Vienna. The full analysis, including a breakdown of the reasons for revision, is available on www.ProvingthePromise.com.
“This most recent analysis adds to the body of evidence on the positive performance of the ATTUNE Knee,” said Joshua Bridgens, DePuy Synthes Franchise Medical Director. “The information and data in this analysis, such as reasons for revision and preliminary findings on patient-reported outcomes, continue to validate the design principles and our expectations for the clinical performance of the ATTUNE Knee.”
