1 · What the graph read from it

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.

2 · The registry

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

purposeThis study aimed to systematically evaluate the existing literature to account for the clinical and functional outcomes, complications and rate of return to sports among patients treated for distal medial collateral ligament (MCL) lesions that are isolated or associated with other knee ligament injuries.

methodsA systematic review was conducted based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Included were studies that reported postoperative clinical and functional outcomes in patients who had undergone surgery for an isolated or combined distal MCL lesion for medial knee instability. The authors evaluated surgical technique, rehabilitation protocol, postoperative outcomes (Lysholm, IKDC and Tegner scores and valgus stress radiograph), and return to sports and complication rates across the included studies.

resultsA total of 70 patients (55 male, 15 female) were included. The mean age at surgery was 26.9 ± 8.2 years. The mean time from injury to surgery was 3.9 ± 3.0 weeks, while the mean follow-up was between 6 and 68 months, with a mean of 45.8 ± 21.4 months. A total of seven (10%) complications were reported and six (8.6%) revision surgeries. The mean Lysholm score on 27 (38.6%) patients was 87.2 ± 7.3, while IKDC2000 was reported only in one study was 62. Regarding return to sport, five articles reported a full return to sports activity after 6-9 months, while when return to sports was evaluated by Tegner reporting a mean value of 7.8 ± 2.4 (range: 3-10).

conclusionNotwithstanding conflicting data, most patients who have undergone distal MCL lesion surgical treatment, either in isolation or associated with knee ligamentous injuries, achieve satisfactory clinical and functional outcomes, a low rate of postoperative complications, and a high rate of return to recreational sports. LEVEL OF EVIDENCE: Level V, systematic review.
