Medial Meniscus Posterior Root Tears Associated With Medial Collateral Ligament Injury in Young and Middle-Aged Adults: A Report of Three Cases.

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
Medial meniscus posterior root tears (MMPRTs) are increasingly recognized as a significant cause of rapid medial compartment degeneration. Although commonly observed in middle-aged patients with degenerative changes, traumatic MMPRTs in younger individuals are uncommon and may be overlooked, particularly when occurring alongside medial collateral ligament (MCL) injuries. Herein, we report three cases of MMPRTs associated with Grades I-II MCL injuries in young to middle-aged adults. All patients sustained a valgus force during athletic activity and were initially diagnosed with isolated MCL injuries based on early magnetic resonance imaging (MRI). Upon referral to our institution, persistent medial joint pain prompted a repeat MRI, which revealed concomitant MMPRTs. Surgical repair was performed 3-4 months postinjury using circumferential fiber augmentation with either transtibial pullout or centralization techniques. Postoperative MRI at 6-12 months showed no progression of meniscal extrusion. Two patients returned to sports, and one discontinued follow-up due to pregnancy. These cases emphasize the importance of considering MMPRT in young patients presenting with MCL injuries. Early treatment is most important to avoid delayed diagnosis and prevent cartilage degeneration.
