Open synovectomy for treatment of tenosynovial giant cell tumors of the knee in children.
Article in Journal of surgical case reports, 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
We present seven pediatric cases of open knee synovectomy for tenosynovial giant cell tumor (TGCT)-four diffuse (D-TGCT) and three nodular (N-TGCT). The mean patient age at surgery was 11.3 ± 4.77 years. Five cases were diagnosed and treated within the past 2 years, indicating an unusually high incidence of TGCT in our institution. Subtotal synovectomy was performed through an anterior parapatellar approach, while posterior lesions were accessed between the semitendinosus and medial gastrocnemius muscles. The mean follow-up period was 39 ± 62.3 months (minimum 12 months). No recurrences were detected on follow-up MRI. Six patients regained full knee range of motion, and none exhibited postoperative monoarthritis. These favorable outcomes support open synovectomy as a safe and effective treatment for knee-localized D-TGCT and N-TGCT, especially in cases with posterior or retrocondylar localization.
