{Abstract}: <B>OBJECTIVE: </B>Quality of care in total knee arthroplasty (TKA) between implants was assessed using a novel composite outcome measure, early optimal recovery (EOR), to indicate ideal clinical outcomes and minimal healthcare resource utilization.<BR><B>METHODS: </B>Patients that underwent primary TKA in the study group (ATTUNE® Knee System) or control group (LCS® COMPLETE Knee System) were included in this retrospective, single-center study. EOR was defined as no complications, no readmissions, no extra outpatient visits, ≤ 48 h length of hospital stay (LOS), and restored range of motion and pain perception at 3-month follow-up. Multivariate logistic regression was used to compare EOR between the study and control groups. Results were adjusted for differences in baseline characteristics and are presented with 95% confidence intervals (CI). Data were collected from a specialized clinic for elective surgeries in the Netherlands, between January 2017 and December 2020.<BR><B>RESULTS: </B>A total of 566 patients (62.4% female, mean age 67 years) were included for analysis; 185 patients (32.7%) underwent TKA in the study group. Compared to the control group, patients in the study group had greater probability of achieving EOR (65.8% [95% CI: 55.1-75.2] vs. 38.9% [95% CI: 32.8-45.3]; p < 0.001), a LOS ≤ 48 h (77.2% [95% CI: 67.7-84.5] vs. 61.4% [95% CI: 54.7-67.7]; p < 0.05), and ideal pain perception at 3-month follow-up (93.3% [95% CI: 85.7-97.0] vs. 78.2% [95% CI: 71.0-83.9]; p < 0.05).<BR><B>CONCLUSIONS: </B>The study group was associated with a greater probability of achieving EOR versus the control group, suggesting improved quality of care.
