[Revision anterior cruciate ligament reconstruction with fluoroscopically controlled positioning of the femoral and tibial bone tunnel].
Review in Operative Orthopadie und Traumatologie, 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
objectiveThe goal of the fluoroscopically controlled tunnel positioning in anterior cruciate ligament (ACL) revision surgery is the prevention of malpositioning of femoral and tibial tunnel resulting in a reduced risk of rerupture of the ACL graft. INDICATIONS: Remaining instability of the ACL after performed surgery, either after tunnel filling or as a single-stage surgery. CONTRAINDICATIONS: Relative: minor instability, contraindications against performing intraoperative x‑rays, advanced osteoarthrosis. Absolute: general contraindications against surgery. SURGICAL TECHNIQUE: Supine position with tourniquet in place and lateral thigh support. Creation of the portals analogous to ACL surgery. Positioning of the drill wires using a targeting device, first femoral, then tibial. Now use of the C‑arm to fluoroscopically check the wire position using the ACL X‑app; correct it if necessary. If the position is adequate, use the quadrant method according to Bernard and Hertel (femoral) or according to Stäubli (tibial) to drill over to the target size of the drill channel. Subsequently, the transplant is drawn in and fixed. If necessary, add additional peripheral stabilization. POSTOPERATIVE MANAGEMENT: Knee brace for 6 weeks postoperatively, limited flexion at 90° for 2-3 weeks, partial weight bearing (20 kg) for 2-3 weeks.
resultsIn the 51 performed ACL revisions performed, there was a postoperative difference of 1 mm in Rolimeter measurement after 6 months.
