No Difference in Early Range of Motion Between CORI Robotic-TKA and Conventional-TKA: A Single-Surgeon Series.

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: Despite the increasing use of robotic-assisted total knee arthroplasty (r-TKA), data on functional outcomes remain limited. This study evaluated 6-week range of motion (ROM) outcomes in patients who underwent r-TKA vs conventional TKA (c-TKA) to determine whether robotic assistance improves early postoperative ROM. Methods: A retrospective analysis was conducted on consecutive patients who underwent primary TKA by a single surgeon using r-TKA or c-TKA between 2019 and 2023. Exclusion criteria included simultaneous bilateral, revision, unicompartmental, and posttraumatic conversion arthroplasties. Knee flexion and extension ROM were measured preoperatively and at standardized 2- and 6-week postoperative visits. Manipulation under anesthesia (MUA) rates for postoperative stiffness were also analyzed. Linear mixed models assessed between-group differences in ROM over time, adjusting for race, sex, body mass index, and preoperative knee alignment. Results: A total of 1124 patients (mean age 65.5 ± 8.7 years) were included, with 729 (64.9%) in the c-TKA cohort and 395 (35.1%) in the r-TKA cohort. Knee extension ROM between the c-TKA and r-TKA groups was not different preoperatively (1.3 ± 6.7 vs 0.8 ± 5.0; Conclusions: Robotic-assisted TKA demonstrated comparable early postoperative ROM and MUA rates to c-TKA. Future studies should explore long-term ROM outcomes and their correlation with patient-reported outcomes to further guide clinical practice. Level of Evidence: III, Retrospective cohort.
