Short-term clinical outcomes of robotic-assisted total knee arthroplasty at 12-month follow-up: a prospective, multicenter, concomitant comparison to conventional total knee arthroplasty.

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
introductionThere is limited data available on short-term outcomes on a cut-block positioning robotic system. The purpose of this study was to compare 12-month clinical outcomes between robotic-assisted (raTKA) and conventional total knee arthroplasty (cTKA) with multiple outcomes and surgical centers.
methodsThis was a non-randomized controlled trial of patients who received either raTKA (n = 120) or cTKA (n = 101) at 6 different surgical centers. Variables of interest included occurrence of soft tissue release, complications and revisions at minimum one-year follow-up. Satisfaction, pain (numeric rating scale [NRS]), 5-dimensional European Quality of Life (EQ-5D-5 L) questionnaire (index and visual analog scale [VAS]), Oxford Knee Score (OKS), and the Forgotten Joint Score (FJS-12) were collected pre-operatively, and at six weeks, three months, and 12 months post-operative.
resultsThere were significantly less soft tissue releases with raTKA (28/120, 23.3%) vs. cTKA (51/99, 51.5%), p < 0.0001). There were significantly fewer cases of medial/lateral instability in the raTKA group at six-weeks (p = 0.038) and three-months (p = 0.007) post-operative. At one-year follow-up, 96.3 and 92.5% of raTKA and cTKA patients were satisfied with the overall results of their surgery, respectively. Significantly more raTKA patients were very satisfied (32.1% vs. 14.6%) with their ability to do home/yard work at six weeks (p = 0.018). Significantly (p = 0.042) less raTKA patients were dissatisfied (5.1% vs. 12.9%) with their ability to perform recreation at one-year post-operative. The EQ-5D-5 L increased significantly (p = 0.042) more in the raTKA group at one-year post-operative (0.529 ± 0.335 vs. 0.417 ± 0.323), but did not exceed the minimal clinical important difference.
conclusionraTKA was associated with fewer soft tissue release procedures and medial/lateral instability with greater satisfaction in performing home/yard work at six-weeks post-operative. raTKA was equivalent to cTKA for overall satisfaction, quality of life, and knee-specific patient reported outcome measures in the early post-operative period. LEVEL OF EVIDENCE: II.
