DePuy Synthes Joint Reconstruction have announced the latest clinical evidence of the performance of its ATTUNE Knee System. The data shows the importance of evidence generation to monitor both the outcomes and economic benefits of new technology. New research from the National Joint Registry (NJR), has shown that the results for the performance of the ATTUNE Knee System compare favourably with the class of cemented total knee systems.
In addition, an analysis of a large US hospital administrative database indicates that ATTUNE Knee patients had 39 per cent lower adjusted odds of discharge to a skilled nursing facility versus patients who received a total knee replacement with a leading competitive knee system, said the company.
The ATTUNE Knee System evidence generation programme is the largest in DePuy Synthes’ history, with multiple streams of ongoing data collection, both company and investigator initiated. Studies observe all four constructs in terms of survivorship, patient-reported outcomes measures (PROMS), learning curve and fluoroscopic kinematics studies. Radiostereometric analysis (RSA) of implant micromotion is also being studied since it has been shown to be predictive of longer-term survivorship. Together, the PROMS, kinematics, RSA studies and survivorship data from national joint registries provide a database of clinical performance of the ATTUNE Knee System.
