Early Results of the Attune Knee System: A Minimum 2 Year Follow Up Observational Study

Background: The ATTUNE Knee System was designed to improve patient outcome and satisfaction. The aims of this study were to assess patient outcome after receiving an ATTUNE total knee replacement (TKR) and ensure early results were comparable to other TKR systems in Australia.
Methods: 332 ATTUNE TKR’s were performed locally, mean follow-up was 2.6 years (2.0 to 3.2). Revision data was collected on all ATTUNE TKR’s. ATTUNE TKR’s performed at our university teaching hospital (n=162), had patient reported outcome measured using the Multi-Attribute Arthritis Prioritisation Tool (MAPT) questionnaire.
Results: Revision rate of the ATTUNE TKR was similar to national rates (1.6% vs. 2.1%) (p=0.508). Postoperative MAPT scores were significantly lower after TKR (n=87) (median 63.4 vs. 0.0) (p<0.001). A total of 82 (94.3%) people had an improved MAPT score post-TKR.
Conclusion: Our findings suggest the ATTUNE TKR has comparable revision rates to other TKRs currently available in Australia. Furthermore, patient reported outcome was good 2.4 years postoperatively.
