Healthcare resource utilization for VELYS™ robotic-assisted solution compared to manual surgery for total knee arthroplasty.
Article in Journal of robotic surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThis study compared healthcare resource utilization associated with the use of VELYS™ Robotic-assisted solution (VRAS) vs. manual surgery for primary total knee arthroplasty (TKA).
methodsElectronic medical records of patients undergoing TKA from a single surgeon at a US critical access hospital (manual surgery: 2019 to 2020; VRAS: 2022 to 2023) were reviewed. The primary clinical/health economic outcome of interest was pain medication use (morphine milligram equivalents [MMEs]). The secondary clinical/health economic outcome of interest was hospital length of stay (LOS). Multivariable logistic regression models accounted for potential confounding.
resultsAmong 452 TKA cases (mean [SD] age 67.4 [9.0] years, 50.2% male), 215 patients (47.6%) received VRAS and 237 (52.4%) received manual surgery. VRAS patients were slightly older (67.9 vs. 66.9 years) and a greater proportion were male (55.7 vs. 46.0%). Unadjusted analyses found manual surgery patients used nearly twice as much pain medication (mean [SD] 156.2 [104.1] vs. 86.2 [83.6] MMEs; p < 0.001) and had longer mean (SD) and median LOS (mean 1.5 [0.7] vs. 1.1 [0.5] days and median 1.2 vs. 1.0 days; p < 0.001). After adjustment for age, sex, body mass index, and American Society of Anesthesiology score, manual surgery patients had 1.7 times higher MME consumption (p < 0.05) and 1.4 times longer LOS (p < 0.05). Further adjustment for differences in baseline comorbidities showed more pronounced differences: manual patients had 2.3 times higher MME consumption (p < 0.05) and 1.8 times longer LOS (p < 0.05).
conclusionsVRAS may facilitate significantly reduced pain medication and shorter LOS with TKA.
