Cadaveric Exploration of the Anatomical Position of the Adductor Canal.
Article in Acta medica academica, 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
objectiveThis study aimed to precisely identify the location of the adductor canal to assist knee surgeons during procedures. MATERIALS AND
methodsWe utilized twenty formalin-fixed cadavers to measure the length of the lower limb from the midinguinal point (MIP) to the base of the patella and divided the measured length into three parts: the proximal, middle, and distal. After dissecting the adductor canal, we measured the distance between the MIP and the proximal foramen and the distal foramen (adductor hiatus), the distance between the distal foramen and the base of the patella, and the length of the adductor canal. We also measured the location of the proximal and distal foramina concerning the upper and lower limits of the middle third of the thigh.
resultsThe mean lengths of the thigh and adductor canal were 39.59±3.6 cm and 15.24±2.26 cm, respectively. The average distances between the MIP and the proximal and distal foramina and between the distal foramen and the base of the patella were 14.39±1.98 cm, 29.56±2.22 cm, and 10.28±1.87 cm, respectively. In 75% of lower limbs, the proximal foramen was below the upper limit of the mid-third of the thigh, with an average distance of 1.74 cm, whereas in 85% of cases, the distal foramen was below the lower limit of the mid-third of the thigh, with an average distance of 3.3 cm.
conclusionThis study suggests that the ideal adductor canal block approach is within the middle third of the thigh.
