ATTUNE® Knee System Four-Year Revision Rate Lower Than Total Class

DePuy Synthes says new ATTUNE® Knee implant survivorship data compares favorably to the 1.9% cumulative revision rate (98.1% implant survivorship at four years) for the overall class of total knee replacement.


New data has emerged from 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% at four years (98.7% implant survivorship at four years).

DePuy Synthes, part of the Johnson & Johnson Family of Companies, tells us that only 46 ATTUNE knees 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 in Vienna, coinciding with the 18th European Federation of the National Associations of Orthopaedics and Traumatology (EFORT) Congress.

Company comments

“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.”
