Subchondral Bone Injections for the Treatment of Knee Osteoarthritis.
Article in The archives of bone and joint surgery, 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
The existing literature on whether subchondral bone injections in knee osteoarthritis is advisable for relieving patient pain is minimal and the level of evidence is low. A recent case series (2023) analyzed 30 individuals with knee OA (Kellgren-Lawrence 2-3). It showed that combined intraarticular and subchondral BMAC (bone marrow aspirate concentrate injections) provided clinical and imaging benefits up to 24 months for the treatment of symptomatic knee OA, with a low failure rate, and a significant reduction of bone marrow edema. Besides, VAS (visual analog scale) pain worsened at the final follow-up, although remained lower compared to the baseline value. Although some studies mention that subchondral bone injections can relieve pain in mild/moderate knee OA, it does not seem reasonable to advise it until better-designed research can confirm the preliminary studies discussed in this article.
