Comparison of Knee Function After Reconstruction With Posterolateral Corner Injury and With or Without Posteromedial Corner Injury for Treating Knee Dislocation Cases: A Prospective Cohort Study.
Article in Orthopaedic surgery, 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
backgroundIn the multiple ligament injury of the knee joint, apart from the anterior cruciate ligament and the posterior cruciate ligament, the Posterolateral Corner and the Posteromedial Corner are two structures that are easily overlooked. If not properly identified and repaired in one stage, the knee joint may be unstable, even failure of cruciate ligament reconstruction. The purpose of this article was to evaluate the effect of knee joint recovery after PLC (Posterolateral Corner) with or without PMC (Posteromedial Corner) injury.
methodsFrom 2016 to 2020, we screened a total of 2564 patients, of which 292 patients met the inclusion and exclusion criteria. In the end, a total of 44 people completed the study. Follow-up was performed at 1, 3, 6, 9, and 12 months after surgery. We used pain visual analog scale (VAS) for pain, IKDC score, Lysholm score, Tegner score. Opti-knee (a portable motion analysis system) was used to evaluate the stability of the knee joint at 1 year. In our prospective cohort study, we used the unpaired Student's t-test for statistical analysis.
resultsThe knee joint function of PLC group and PLC combined PMC group was better than that before operation at 3 or 6 months after operation. Except for IKDC at 9-month follow-up and Tegner score at 9-month and 12-month follow-up, there was no significant difference between the other groups.
conclusionsPLC and PLC combined with PMC injury showed similar prognostic effects, although the PLC group was numerically superior to the other group. We recommend primary repair and reconstruction in patients with confirmed PLC and PMC injuries to achieve the best postoperative recovery.
