London, UK – 20 April 2017 – Today, DePuy Synthes, part of the Johnson & Johnson Family of Companies, released the report, “Improving the Value of Primary Total Knee Arthroplasty: the ATTUNE® Knee System,” that analyzes the ATTUNE Knee’s current clinical and economic data. The report concludes that in a value-based healthcare environment with cost constraints and growing procedure volumes, the value of a knee replacement implant is measured not only by how long the implant lasts (implant survivorship), but also through patient reported outcomes and the economic benefits of the procedure.
The report, which was released during the European Knee Society Arthroplasty Conference in London, was commissioned by DePuy Synthes and is authored byDavid Fisher*, M.D., Director of the Total Joint Center of Excellence at OrthoIndy Hospital in Indianapolis, Indiana, and Professor David Parkin, an Honorary Visiting Professor at City, University of London and a Senior Visiting Fellow, Office of Health Economics.
The report analyzes approaches for evaluating primary total knee arthroplasty (TKA) from a clinical and health economic perspective, and assesses the current data from DePuy Synthes’ ATTUNE Knee Evidence Generation Program. This program, the largest of its kind in DePuy Synthes’ history, includes a wide range of data from company-initiated studies, investigator-initiated studies, independent studies and national joint registries.
In their analysis, Dr. Fisher and Professor Parkin conclude that, “Based on available data, the ATTUNE Knee appears to be advancing outcomes for patients and creating value for clinicians, providers and payors in a challenging and dynamic healthcare environment.”
This report comes at a time when the entire episode of patient care is a major focus for global healthcare providers, placing a laser-like focus on both improving patient outcomes and managing costs.The introduction of the “Hospital Structure Act” in Germany and the“Payments by Results” system in England are two examples of the drive to minimize the total cost of care while maintaining quality. Against this backdrop, data from a comprehensive evidence generation program could help provide evidence to support decisions about a device’s overall value.
“The success of any knee replacement is multifactorial, and the data on the ATTUNE Knee gives me confidence that I’m using a knee replacement that is delivering value for patients and the healthcare system,” said Dr. Fisher.
Added Professor Parkin:“Quality of life, as measured by patient reported outcomes, has been shown to be a driver of cost effectiveness in knee replacement. The evidence that I’ve seen about the effectiveness of the ATTUNE Knee in improving patient reported outcomes suggests it could deliver a better quality of life for patients compared to some other leading knee systems. Therefore, the ATTUNE Knee may potentially play a role in helping reduce some of the healthcare and societal costs associated with knee osteoarthritis.”
According to the analysis, the ATTUNE Knee has thus far demonstrated favorable survivorship, improved patient reported outcomes versus other knee systems, as well as potential economic benefits:
- Survivorship: The published report from the National Joint Registry for England, Wales, Northern Ireland and the Isle of Man (NJR) showed that the ATTUNE Knee’s estimated cumulative percent revision was 1.39% at three years (98.61% survivorship) for 4,463 knees, comparing favorably to the class of Cemented Total Knee Arthroplasty that has an estimated cumulative percent revision of 1.50%1. In addition, per the 2016 Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR), in which 4,831 ATTUNE Knees are being tracked, the ATTUNE Knee’s estimated cumulative percent revision was 0.5% (ATTUNE Cruciate Retaining Knee) and 0.4% (ATTUNE Posterior Stabilized Knee) at one year.2 This compares favorably to the overall class of cemented TKA at one year, which has an estimated cumulative percent revision of 1.0 percent.2
- Patient Reported Outcomes:DePuy Synthes has taken the lead in this area by helping generate and validate a new measure, the Patient’s Knee Implant Performance (PKIP), to specifically assess the functional status of a patient’s knee from their own perspective. Results of a study using PKIP as well as other commonly used generic and condition-specific patient reported outcome measures showed that, at one year, study participants implanted with the ATTUNE Knee had statistically significant improvements compared to some other leading knee systems used in the study, in terms of confidence in stability during activity, decreased anterior knee pain, activities of daily living and quality of life.3
- Health Economics: Results from a database analysis review conducted across a selection of US hospitals showed 39% lower adjusted odds of patient discharge to a skilled nursing facility when patients in the dataset were implanted with an ATTUNE Knee, compared to patients who received total knee replacement with a Triathlon® Knee.4 In addition, one study showed that up to 35% of episodic costs were related to post hospital discharge care5 and another showed it was up to 50%.6 Given that post discharge costs are a significant portion of the overall episode of care, these results indicate healthcare costs may therefore be reduced.
