This study assessed (1) healthcare utilization (length of stay (LOS), nonhome discharge, 90-day readmission, and 1-year reoperation); (2) 1-year mortality; and (3) 1-year joint-specific and global health-related patient-reported outcome measures (PROMs) among patients who received cementless versus cemented TKA. Patients who underwent cementless and cemented TKA at a single institution (July 2015\u2013August 2018) were prospectively enrolled. A total of 424 cementless and 5,274 cemented TKAs were included. The cementless cohort was propensity score-matched to a group cemented TKAs (1:3-cementless: n\u2009=\u2009424; cemented: n\u2009=\u20091,272). Within the matched cohorts, 76.9% (n\u2009=\u2009326) cementless and 75.9% (n\u2009=\u2009966) cementless TKAs completed 1-year PROMs. Healthcare utilization measures, mortality and the median 1-year change in knee injury and osteoarthritis outcome score (KOOS)-pain, KOOS-physical function short form (PS), KOOS-knee related quality of life (KRQOL), Veteran Rand (VR)-12 mental composite (MCS), and physical composite (PCS) scores were compared. The minimal clinically important difference (MCID) for PROMs was calculated. Cementless TKA exhibited similar rates of median LOS (p\u2009=\u20090.109), nonhome discharge disposition (p\u2009=\u20090.056), all-cause 90-day readmission (p\u2009=\u20090.226), 1-year reoperation (p\u2009=\u20090.597), and 1-year mortality (p\u2009=\u20090.861) when compared with cemented TKA. There was no significant difference in the median 1-year improvement in KOOS-pain (p\u2009=\u20090.370), KOOS-PS (p\u2009=\u20090.417), KOOS-KRQOL (p\u2009=\u20090.101), VR-12-PCS (p\u2009=\u20090.269), and VR-12-MCS (p\u2009=\u20090.191) between the cementless and cemented TKA cohorts. Rates of attaining MCID were similar in both cohorts for assessed PROMs (p\u2009&gt;\u20090.05, each) except KOOS-KRQOL (cementless: n\u2009=\u2009313 (96.0%) vs. cemented: n\u2009=\u2009895 [92.7%]; p\u2009=\u20090.036). Cementless TKA provides similar healthcare-utilization, mortality, and 1-year PROM improvement versus cemented TKA. Cementless fixation in TKA may provide value through higher MCID improvement in quality of life. Future episode-of-care cost-analyses and longer-term survivorship investigations are warranted.<\/jats:p>","DOI":"10.1055\/s-0041-1739201","type":"journal-article","created":{"date-parts":[[2021,11,16]],"date-time":"2021-11-16T00:03:31Z","timestamp":1637021011000},"page":"530-539","source":"Crossref","is-referenced-by-count":12,"title":["Similar
