Outcomes of arthroscopic one-stage repair and reconstruction of Schenck II-IV knee dislocations with multiple ligament injuries: a single-center study.
Article in BMC surgery, 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
objectiveTo evaluate the outcomes of arthroscopic one-stage repair and reconstruction of Schenck II-IV knee dislocations with multiple ligament injuries.
methodsWe retrospectively reviewed the data of patients with Schenck II-IV knee dislocations and multiple ligament injuries treated in our hospital during 2019-2022. Patients underwent single-bundle reconstruction of the cruciate ligaments via an arthroscopic all-inside technique, along with repair/reconstruction of the collateral ligaments if necessary, and management of concomitant injuries. Knee joint function was evaluated using the International Knee Documentation Committee (IKDC) score, Lysholm score, Tegner activity score, visual analog scale (VAS) score, and range of motion.
resultsAll 38 patients (27 men, 11 women; ages, 17-58 years) were followed up for 24-36 months. No postoperative neurovascular or thrombotic complications occurred. For all patients, IKDC (35.76 vs. 83.16, P < 0.001), Lysholm (41.97 vs. 88.63, P < 0.001), Tegner activity (1.18 vs. 6.29, P < 0.001), and VAS scores (3.89 vs.0.21, P < 0.001), and active range of motion (87.08° vs. 126.24°, P < 0.001) were significantly better at the final follow-up than before surgery. The drawer test, Lachman test, pivot shift test, knee varus and valgus stress tests at 0° and 30°, and tibial external rotation test all turned negative after the surgery. Four patients (10.5%) returned to their pre-injury activity levels. All patients achieved grade V muscle strength at 1 year. One patient with preoperative thrombosis underwent anticoagulant treatment and developed no serious complications. A patient with peroneal nerve injury did not experience complications after decompression and postoperative exercises. All meniscus injuries were repaired if indicated.
conclusionsAcute one-stage arthroscopic reconstruction after knee dislocation with multiple ligament injuries yields satisfactory postoperative knee joint function. This surgical technique can be a treatment option for severe knee injuries.
