Clinical benefits of pie-crusting the medial collateral ligament for medial meniscal disease: a systematic review and meta-analysis.

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
backgroundThis study aims to conduct a systematic review and meta-analysis of the existing literature concerning the percutaneous medial collateral ligament release technique, assessing its effectiveness during medial meniscal arthroscopy, with a particular focus on clinical outcomes and radiological impacts.
methodsA systematic review was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, utilizing a PRISMA checklist. A comprehensive electronic search was conducted using PubMed, EMBASE, and Cochrane Library databases to identify studies involving percutaneous medial collateral ligament release during arthroscopic knee surgery with reported postoperative outcomes. Only articles published in English or Chinese were included, while studies related to total knee arthroplasty, cadaveric specimens and concomitant knee injuries were excluded. Literature screening, data extraction, and risk of bias assessments were meticulously executed by two independent authors to ensure the robustness and reliability of the findings. The outcome measures were the Lysholm Score, the IKDC Score, and joint space width.
resultsAmong the 180 studies initially identified, 13 studies met the predetermined inclusion criteria and were subsequently incorporated into this systematic review and meta-analysis. The pie-crusting group exhibited significantly higher Lysholm and IKDC scores at 24 months compared to non-pie-crusting controls (p = 0.001 and p = 0.0006, respectively). Additionally, there was no statistically significant difference in joint space width observed between the preoperative measurements and those collected at the 24-month follow-up (p = 0.73). No complications or adverse effects associated with the pie-crusting procedure were reported.
conclusionThis systematic review and meta-analysis provide compelling evidence for the clinical effectiveness of percutaneous medial collateral ligament release during arthroscopic meniscal surgery for patients with a narrow medial joint space. The pie-crusting technique enhances surgical visualization and improves postoperative clinical outcomes, all while maintaining a favorable safety profile with no increase in the risk of complications or joint instability. These findings collectively underscore the safety and efficacy of the pie-crusting technique as an adjunctive procedure in medial meniscal arthroscopy.
