Bilateral Patellar Avascular Necrosis Following Total Knee Arthroplasties.
Article in Cureus, 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
A 79-year-old female with a history of bilateral knee osteoarthritis presented with severe knee pain, eight years post-bilateral total knee arthroplasties (TKAs). Notably, a lateral retinacular release had been performed alongside each arthroplasty. On examination, she displayed new painful prominences along the lateral aspects of both knees. Radiographs and CT scans revealed near-complete resorption of the bilateral patellae, indicating advanced avascular necrosis (AVN). After discussing treatment options, the patient opted for revision surgery to remove the patellar hardware, leading to significant improvements in pain, function, and mobility. This case underscores the need for close, long-term follow-up in patients who undergo TKA with concurrent lateral retinacular release, to monitor for potential complications like AVN.
