UTILIZATION OF ROBOTIC ARM ASSISTANCE FOR REVISION OF PARTIAL TO TOTAL KNEE ARTHROPLASTY: A CASE REPORT.
Article in Acta ortopedica brasileira, 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
Introduction: The introduction of robotic-assisted total knee and hip arthroplasty in Brazil since 2021 has demonstrated benefits, including greater precision in bone cuts and reduced tissue trauma. However, there is a lack of studies on the use of this technology in TKA revisions. This report presents the first robot-assisted TKA performed in Brazil, representing an innovative and pioneering approach. Case report: A 61-year-old female patient presenting with pain and limited flexion in her left knee, who underwent unicompartmental knee arthroplasty (UKA) in 2015. After conservative treatment with physical therapy and injections proved ineffective, it was decided to proceed with robot-assisted total knee arthroplasty. The procedure followed the Mako protocol, which included robotic anatomical marking, removal of the previous components, and ligament adjustments. Precise bone cuts were made using the robotic arm, followed by the cementation of prosthetic components. The surgery went smoothly, with a favorable postoperative course. Conclusion: The use of robotic assistance in revision anterior cruciate ligament surgery has proven promising, yielding good postoperative results. However, further studies are needed to standardize the technique and establish specific protocols.
