Effects of Anteromedial Portal versus Transtibial ACL Tunnel Preparation on Contact Characteristics of the Graft and the Tibial Tunnel Aperture.
Article in Clinics in orthopedic surgery, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers.
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
backgroundThe purpose of this study was to compare the tibial tunnel aperture contact characteristics simulating an anteromedial and transtibial anterior cruciate ligament (ACL) tunnel preparation.
methodsSeven matched pairs of cadaveric knees were tested. From each knee, a 10-mm quadriceps ACL graft was prepared. The native ACL was arthroscopically removed and tibial tunnels were drilled. In one knee, a transtibial technique was performed with femoral tunnel drilling approached through the tibial tunnel. For the anteromedial technique on the contralateral knee, the posterior tibial tunnel was chamfered with a rasp. The knees were then disarticulated and tibial tunnel aperture geometry was measured. A pressure sensor was placed between the graft and the posterior aspect of the tibial tunnel and the graft was secured with an interference screw. Contact force, contact area, contact pressure, peak contact pressure, hysteresis and stiffness were measured at cyclic loads of 50 N, 100 N, 150 N, and 200 N.
resultsTibial tunnel aperture area, diameter and deviation from a circle were significantly larger with the transtibial technique (
conclusionsIncreased peak contact pressure on the graft at the tibial aperture with the anteromedial technique may increase the stress on the graft and possibly lead to failure following ACL reconstruction.
