Effects of arthroscopic meniscectomy or meniscoplasty of discoid meniscus on lower limb axial alignment: a systematic review and meta-analysis.
Synthesis in BMC musculoskeletal disorders, 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
backgroundThe purpose of this study was to investigate the effect of meniscectomy and meniscoplasty on the lower limb axial alignment in patients with discoid meniscus (DM).
methodA literature search was conducted in both Chinese and English databases (Chinese search bases: China National Knowledge Infrastructure, Wanfang, and China Science and Technology Journal Database; English search bases: PubMed, Embase, Cochrane Library, Web of Science). In the bilateral experiments, the weighted mean difference (WMD) with a 95% Confidence Interval (CI) was used as the pooled effect size, while the Effect Size (ES) with 95%CI was used for continuous variables in single-group experiments.
resultsTotally, 11 papers were included. There was no statistically significant difference in the post-arthroscopic surgery outcomes when comparing DM and non-DM in terms of mechanical axis deviation (MAD), mechanical lateral distal femoral angle (mLDFA), tibiofemoral angle (TFA), lateral knee space, and Lysholm score (all P > 0.05). The mechanical proximal tibia angle (mPTA) improvement after DM surgery was lower than that after non-DM surgery (P < 0.05). No significant differences were found in MAD, mLDFA, TFA, or lateral knee space after various arthroscopic DM surgeries (all P > 0.05).
conclusionPostoperative lower limb axial alignment and knee function did not significantly differ between DM and non-DM patients, nor did they vary substantially with different surgical approaches for DM. This study suggests that further and more in-depth research is needed to assess the changes in lower limb axial alignment following surgery in patients with DM.
