Post-traumatic Patellofemoral Ankylosis treated with Robotic Arm Assisted Patellofemoral Arthroplasty - A Case Report.
Article in Journal of orthopaedic case reports, 2025. 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: This case report describes the procedure and 2-year outcome in a patient with bony patellofemoral ankylosis who underwent robotic arm-assisted patellofemoral arthroplasty (RA-PFA). Case Report: A 21-year-old male with Post-traumatic Patellofemoral Ankylosis with quadriceps contracture underwent RA-PFA with Quadriceps-plasty. Preoperatively, the patient had a flexion deformity of 20° with no further active flexion or extension. Passive knee extension from 20° to 0° was possible. At 2-years follow-up, he was independently ambulant with good improvement in pain and functional clinical scores. He had an improved active flexion of 0°-80° and active extension of 80°-0° with no extension lag. Conclusion: This case suggests RA-PFA may be an effective intervention to restore knee function in Post-traumatic Patellofemoral Ankylosis despite the grossly altered anatomy.
