A Case Report of Unicompartmental Knee Arthroplasty Fracture of the Femoral Component.
Article in Journal of orthopaedic case reports, 2023. 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: Unicompartmental knee arthroplasty (UKA) is performed with yearly rate of 9% in UK, and <8% in USA. It has been shown to be a successful and less invasive alternative to complete knee arthroplasty in certain patients total knee arthroplasty (TKA). Fracture of the femoral component after (UKA) has never been reported in the literature. Consequently, to investigate the major causes and mechanisms of (UKA) failure, we present a case of femoral component failure following (UKA). Case Report: A 62-year-old patient with 2 years following an UKA presented with a right pain, stiffness, and gait abnormalities. After taking full history and careful examination and obtaining a new radiograph, a fracture of the femoral component was revealed. A revision surgery with TKA has been done, and the outcome was assessed regularly, and good results were achieved. Conclusion: The exact reason for a femoral component fracture following UKA is yet unknown. To make an early diagnosis and avoid the need for complex knee revision surgeries, long-term follow-up is crucial for early detection of the clinical signs and symptoms of implant failure.
