Sagittal accuracy and functional impact of tibial slope in imageless robotic-assisted Total Knee Arthroplasty.
Article in International orthopaedics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
purposeStudy of the sagittal accuracy of the 'Robotic Surgical Assistant' (ROSA
methodsInclusion of patients who underwent primary Total Knee Arthroplasty (TKA) between 1/1/2021 and 15/4/2024. Divided into robotic-assisted TKA (RA-TKA) and manual TKA (M-TKA). Measurement of pre- and post-operative TS, using the posterior tibial cortex, on profile knee X-rays. 3° TS applied arbitrarily for both groups. ROM was measured pre-operatively and at three, six and 12 months post-operatively. Patient satisfaction assessed via Knee Injury and Osteoarthritis Outcome Score (KOOS) and Oxford Knee Score (OKS).
results266 patients were included in the study. The M-TKA (110) had a post-operative TS of 3.11° (± 2.12°). 81.21% were within 2° of the target and 92.87% within 3°. The RA-TKA (82) had a post-operative TS of -0.11° ± (1.93°). 36.83% were within 2° of the target and 56.63% within 3°. RA-TKA had a KOOS of 64.43 ± 12.87 and OKS of 33.05 ± 6.01. M-TKA had a KOOS of 64.18 ± 13.11 and OKS of 32.31 ± 5.97. Maximum flexion at 12 months was 118.74° ± 8.19° for M-TKA and 121.88° ± 7.43° for RA-TKA (p = 0.002).
