Robotic-Assisted Primary Total Knee Arthroplasty is Associated With Decreased 90-Day Opioid Prescribing Patterns Compared to Manual Instrumentation.

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
Background: Robotic assistance minimizes bony resection and surrounding soft tissue damage during total knee arthroplasty (TKA), potentially decreasing postoperative pain. The objective of this study was to evaluate in-hospital opioid consumption, 90-day opioid prescribing patterns, length of stay (LOS), and patient-reported outcome measures (PROMs) following robotic-assisted vs manual primary TKA. Methods: Utilizing an institutional database, all patients undergoing primary unilateral TKA between 2019 and 2022 with 90-day minimum follow-up were retrospectively queried. Patients were excluded if they had another surgery within 90 days of the index TKA, were discharged to a rehabilitation center, or were prescribed opioid or benzodiazepine medications preoperatively. One-to-one propensity score matching identified 1476 patients undergoing robotic-assisted (n = 738) or manual (n = 738) TKA. Multivariable regression analysis assessed in-hospital morphine milligram equivalents (MMEs) consumption, LOS, 90-day opioid prescribing patterns (not necessarily consumption), and PROMs (preoperative, 6 weeks, and 3 months). Results: The robotic-assisted cohort consumed on average 12 fewer in-hospital MMEs ( Conclusions: Robotic-assisted TKA may confer shorter LOS with decreased 90-day opioid use patterns. This information is important given the increased scrutiny on opioid usage and recent focus on rapid recovery and ambulatory TKA pathways.
