Inter- and intra-operator variability in ligament balance measurements in total knee arthroplasty with the robotic navigation system (ROSA®): in vivo study.
Article in International orthopaedics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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 quantifies the reproducibility of soft tissue laxity and gap measurements under manual stress, and implant positioning planning using the imageless ROSA
methodsIn this single-centre prospective study, 17 patients undergoing robotic-assisted total knee arthroplasty were evaluated. Intra- and inter-operator variability was assessed by recording intraoperative measurements and planning outcomes using a standardized protocol for functional alignment (FA).
resultsBoth intra and inter-operator analyses demonstrated good to excellent reproducibility (ICC > 0.75-0.9) for soft tissue and gap assessments. Minor variability was observed in planning parameters (ICC < 0.60), specifically stylus height, femoral flexion, and distal femoral resection, likely reflecting subjective adjustments by the high-volume surgeon.
conclusionHigh reproducibility in soft tissue measurements and surgical planning across surgeons with different experience levels is shown by the ROSA
