Transcatheter Arterial Embolization of Abnormal Neovessels for Patellar Tendinopathy: A Safety Evaluation: A Proof-of-Concept Study.
Article in Orthopaedic journal of sports medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Background: Patellar tendinopathy (PT) is common among athletes, and the current care is largely palliative. Purpose: To evaluate the safety of transcatheter arterial embolization (TAE) in patients with PT refractory to nonoperative treatments. Study Design: Case series; Level of evidence, 4. Methods: This was a multicenter, retrospective study in which recalcitrant PT was treated using TAE. TAE was performed by infusing temporary embolic material through a catheter inserted into the targeted genicular artery. Complications, numeric rating scale (NRS) for pain, Victorian Institute of Sport Assessment for the patella (VISA-P), time to return to training, and ultrasound findings were reported. Results: Between March 2017 and February 2023, a total of 98 patients with PT underwent TAE. Nine patients were lost to follow-up, and the remaining 89 patients (69 male; mean age, 26.1 ± 11.9 years) were followed up for 1 to 7 years (mean, 31.2 ± 16.1 months) after TAE. No major complications were observed. Mean VISA-P score improved from 24.9 ± 15.3 at baseline to 43.2 ± 21.6, 55.2 ± 22.3, and 67.4 ± 24.7, at 1, 3, and 6 months of follow-up, respectively. Mean NRS for pain improved from 7.6 ± 1.4 at baseline to 4.5 ± 2.3, 3.5 ± 2.4, and 2.7 ± 2.4 at the corresponding time points. VISA-P and NRS scores were 74.6 ± 26.2 and 2.3 ± 2.7, respectively, at the final follow-up. Mean times for return to light and full training were 7.8 ± 8.7 and 14.3 ± 11.5 weeks, respectively. Ultrasound demonstrated decreased patellar tendon thickness (9.5 ± 1.8 mm at baseline vs 6.6 ± 1.3 mm at the final follow-up) without tendon ruptures. Conclusion: TAE can be considered a safe alternate to existing treatment options for recalcitrant PT. A randomized controlled trial is required to elucidate its efficacy.
