| description | OBJECTIVESPrevious studies on Medicare populations have shown improved outcomes and decreased 90-day episode-of-care costs with robotic arm-assisted total knee arthroplasty (RATKA). The purpose of this study was to evaluate expenditures and utilization following RATKA in the population younger than 65 years. STUDY DESIGNThis is a retrospective longitudinal analysis of a commercial claims data set. METHODSTKA procedures were identified using the OptumInsight Inc database. The procedures were stratified in 2 groups: the RATKA and manual TKA (MTKA) cohorts. Propensity score matching was performed at 1:5. Utilization and associated costs were analyzed for 90 days following the index procedure. A total of 357 RATKA and 1785 MTKA procedures were included in this analysis. RESULTSWithin 90 days post surgery, patients who had RATKA were less likely to utilize inpatient services (2.24% vs 4.37%; P = .0444) and skilled nursing facilities (1.68% vs 6.05%; P |

No patients in the RATKA group went to inpatient rehabilitation, whereas 0.90% of the MTKA arm went to an inpatient rehabilitation facility. Patients who utilized home health aides in the RATKA arm utilized significantly fewer home health days (5.33 vs 6.36 days; P = .0037). Costs associated with overall postsurgery expenditures were $1332 less in the RATKA arm ($6857 vs $8189; P = .0018). The 90-day global expenditures (index plus post surgery) were $4049 less in the RATKA arm ($28,204 vs $32,253; P < .0001). Length of stay after surgery was nearly a day less for the RATKA arm (1.80 vs 2.72 days; P < .0001). CONCLUSIONSRATKA was associated with shorter length of stay, reduced utilization of services, and reduced 90-day payer costs compared with MTKA.</description><identifier>ISSN: 1088-0224</identifier><identifier>EISSN: 1936-2692</identifier><identifier>DOI: 10.37765/ajmc.2020.43763</identifier><language>eng</language><subject>Health administration</subject><ispartof>The American journal of managed care, 2020-07, Vol.26 (7), p.e205-e210</ispartof><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c276t-5c018adbe0a16d8f0ebf399405718bb6e9c8df4993b74d0b7eab2eb28a0df2763</citedby></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>314,776,780,27901,27902</link.rule.ids></links><search><creatorcontrib>Pierce, James</creatorcontrib><creatorcontrib>Needham, Keith</creatorcontrib><creatorcontrib>Adams, Christopher</creatorcontrib><creatorcontrib>Coppolecchia, Andrea</creatorcontrib><creatorcontrib>Lavernia, Carlos</creatorcontrib><title>Robotic Arm–Assisted Knee Surgery: An Economic Analysis</title><title>The American journal of managed care</title><description>OBJECTIVESPrevious studies on Medicare populations have shown improved outcomes and decreased 90-day episode-of-care costs with robotic arm-assisted total knee arthroplasty (RATKA).
