“…Interestingly, we found the Attune implant is associated with decreased absolute length of stay (Table 3), as shown in industry-funded research [32]. However, there was no difference by implant for an extended length of stay over 3 days (Table 3, Appendix 3), contrary to other reported data [33]. The increased sizing options to match patient anatomy may improve mechanical performance of the joint, provide ease of mobility, and result in earlier absolute discharge in the Attune patients.…”

Background-Newer implants for total knee arthroplasty (TKA) often gain market share at higher cost with little patient-reported and long-term clinical data. We compared outcomes after TKA using two different implants: Depuy PFC Sigma and Attune.Methods-Using a prospective data repository from an academic tertiary medical center, we analyzed 2116 TKAs (1603 Sigma and 513 Attune) from April 2011 through July 2016. Outcomes included length of surgery, length of stay, facility discharge, 90-day reoperation, range of motion (ROM) change, and patient-reported physical function (PCS).Results-There was no difference in length of surgery (Attune −2.87 minutes, P=0.143). Implant type was not associated with extended LOS (>3 days) (OR 0.80, P=0.439). There was no difference in facility discharge (OR 0.65, P=0.103). Unadjusted 90-day reoperations were 0.3% for *

“…First results for the ATTUNE Knee System with primary TKA in the UK indicate that a strong potential to LOS can be associated with the ATTUNE Knee System. At the Nottingham University Hospital a reduction of 1 day from 6.6days with the ATTUNE Knee System compared to the Columbus ® Knee (95%CI: 0.1–1.9, P =0.0197) and of 0.8 days from 6.4 days compared to the SIGMA ® Knee (95%CI: 0.1–1.5, P =0.0212) could be achieved whilst improving patient outcomes 16…”

Background Although total knee arthroplasty (TKA) procedures are increasing, patient satisfaction is still inferior compared to total hip arthroplasty. The ATTUNE ® Knee System was designed to reduce pain and improve function, leading to greater patient satisfaction and decreased resource utilization in TKA. The objective of this study was to compare length of stay (LOS) of TKA with ATTUNE knee versus LCS ® knee implants. Methods A retrospective chart review analysis in a German center was conducted between 2008 and 2016. All patients without prior ipsilateral knee operation, treated with a cemented LCS or ATTUNE knee were included. Endpoints captured included gender, age, availability of home support, prior contralateral TKA, ASA grade and LOS. Statistical analyses included chi-squared test for differences in patient demographics and Welch two-sample t -test for difference in LOS. Results Mean LOS in the ATTUNE Knee group (N=85) was 8.3 days (SD: 1.79) compared to 10.4 days (SD: 1.91) in the LCS knee group (N=85). No significant differences in gender, age, availability of home support, prior contralateral TKA, or ASA grade between both cohorts were observed. The 2.1 days reduction was statistically significant ( P <0.001; 95%CI: 2.7–1.6). A sensitivity analysis outlined the impact of the study duration: even when assuming that 1.3 days reduction resulted from the observed national LOS decrease, the remaining 0.8 reduction in days LOS reduction was still significant ( P <0.01). Conclusion When comparing two cohorts with similar sociodemographic and medical factors, LOS of ATTUNE knee patients was 2.1 days shorter than patients treated with the LCS knee.

“…In addition to the clinical benefits observed with the use of one of these adapted design implants [5,9e11], improvements in endpoints which influence healthcare costs, such as hospital length of stay (LOS) and discharge destination have also been demonstrated; a recent US database study for example, demonstrated statistically significant reductions in LOS (P < .001), a reduced likelihood of discharge to a rehabilitation center (P < .001), and significantly reduced hospital costs (P < .01) when compared with another implant [15]. Singlecenter studies in other countries including Germany [16], Italy [17], and the UK [18] have also reported statistically significant reductions in LOS among patients receiving this adapted design implant vs the alternative devices examined in those studies.…”
