Better radiological outcomes but equal clinical function of a novel knee arthroplasty robot system: a prospective randomized controlled trial.
Trial report in International orthopaedics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
purposeThis study aimed to evaluate the early clinical and radiological outcomes of robot assisted total knee arthroplasty, and to determine the efficiency and safety of its bone resection and implant positioning of the novel robot system.
methods144 patients who underwent primary TKA were enrolled in this prospective, multicenter RCT conducted in three hospitals. five patients were lost to follow-up at six weeks after surgery. Therefore, 139 patients (73 in the RA TKA group and 66 in the CI TKA group) remained in the final analysis. The primary outcome was the rate of patients whose postoperative alignment was less than 3° deviated from the planned evaluated by full-length weight-bearing X-rays of the lower limb at 12 weeks postoperatively. Secondary outcomes included coronal and sagittal alignment of the components, operation times, blood loss, 12-week range of motion(ROM), 12-week postoperative functional outcomes and satisfaction evaluated by the American Knee Society Score (KSS) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and adverse events (AEs).
resultsAt 12 weeks postoperatively, we found the rate of radiographic inliers was significantly higher in the RA TKA group (90.4% vs. 59.1%; p < 0.05). The difference between planned and postoperative frontal femoral component (FFC) angle, frontal tibia component (FTC) angle and lateral femoral component (LFC) angle are significantly smaller in the RA TKA group (p < 0.05). The operation time was significantly longer in the RA TKA group than in the CI TKA group (133.01 vs. 92.33 min; p < 0.05). There was no significant difference in blood loss, 12-week ROM, 12-week postoperative functional outcomes and satisfaction evaluated by KSS and WOMAC scores. There were no AEs or SAEs that were determined to be "related" to the robotic system.
conclusionThe novel robot assisted TKA is safe and more precise in bone resection and implant positioning as demonstrated in this trial.
