Anteromedial Knee Pain Unmasked: Schwannoma of the Infrapatellar Branch of the Saphenous Nerve - A Rare Case Report.
Article in Journal of orthopaedic 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
Introduction: Schwannomas are benign, encapsulated peripheral nerve sheath tumors derived from Schwann cells. They are rarely seen around the knee, accounting for <1% of all schwannomas, and can mimic other benign swellings such as ganglion cysts or bursae. Case Report: We report a 32-year-old female who presented with anteromedial right knee pain and a tender swelling for 2 years. Radiographs were normal, and a provisional diagnosis of a ganglion cyst was made. The lesion was excised under local anesthesia through a vertical incision and found to be a well-encapsulated mass measuring approximately 1 × 1 × 1 cm, located superficial to the joint capsule. Based on its location, the swelling was suspected to arise from a branch of the saphenous nerve, most likely the infrapatellar branch. Histopathological examination confirmed the diagnosis of schwannoma. Conclusion: Schwannomas, though benign and uncommon around the knee, should be included in the differential diagnosis of localized knee pain with soft-tissue swelling and normal radiographs.
