Accuracy assessment of an artificial intelligence model in predicting intraoperative bone resection parameters for robotic-assisted total knee arthroplasty.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
The purpose of this study is to preliminarily evaluate the performance of our AI-assisted decision-making system compared to the final intraoperative parameters obtained under the supervision of the operating surgeon. This prospective study included 52 patients (54 knees) undergoing primary robotic-assisted TKA from November 2024 to February 2025. The AI system, developed from retrospective data, incorporated 17 parameters including resection depths, angles and gap measurements. We compared initial osteotomy parameters, AI predictions, and final implemented parameters. Accuracy was categorized as high (0–1 mm/°), medium (1–2 mm/°), or low precision (> 2 mm/°). The AI system achieved high precision across all parameters. For femoral varus/valgus angle, 100.00% of predictions fell with high precision, with 59.26% exactly matching final resection. Medial distal femoral resection showed 87.04% high precision. Similar high precision rates were observed for lateral distal femoral resection (83.33%), femoral rotation (88.89%), posterior condylar resections (98.15% medial, 92.59% lateral), and tibial resections (83.33% medial, 94.44% lateral and 88.89% for tibia varus/valgus angle). The AI decision support system demonstrated remarkable accuracy in predicting bone resection parameters for robotic-assisted TKA. These findings support AI integration in preoperative planning to enhance surgical precision and efficiency.
