Ultrasound-Guided Manual Therapy for the Infrapatellar Branch of the Saphenous Nerve Entrapment Presenting as Anterior Knee Pain: A Case Report.
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
The infrapatellar branch of the saphenous nerve (IPBSN) is the sensory branch that supplies the anteromedial knee. While iatrogenic injury following knee surgery is well documented, spontaneous or activity-related IPBSN entrapment is under-recognized and can mimic common extensor mechanism disorders. Herein, we present the case of a male physical education teacher in his 20s who developed reproducible anterior knee pain with lunge movements after repeated basketball jumps. The initial clinical suspicion was patellar tendinopathy; however, high-resolution ultrasound (HRUS) revealed IPBSN entrapment at the sartorius penetration site. Manual decompression of the sartorius muscle immediately alleviated the pain. Subsequently, ultrasound-guided soft tissue mobilization was performed, resulting in complete resolution of pain. This case highlights the diagnostic value of HRUS and introduces ultrasound-guided manual therapy as a potentially safe and effective conservative option for treating IPBSN presenting with anterior knee pain.
