Synthesis in BMC musculoskeletal disorders, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07202390 (Intraarticular Gold Microparticles for Knee Osteoarthritis. A Randomized Trial), which is not on this map. Cited by 11 papers.

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.

Abstract

backgroundStudies comparing the effectiveness of arthroscopic knee surgery and conservative treatment on knee osteoarthritis (OA) came up with inconsistent results. Systematic review on this topic still is still lacking. This systematic review and meta-analysis aimed to evaluate the effectiveness of arthroscopic knee surgery on knee OA, compared to conservative treatments. MATERIALS AND

methodsLiterature searches were performed in PubMed, Embase, and Cochrane Library databases for randomized controlled trials (RCTs) published before on 1st July 2024. Studies comparing the effectiveness of arthroscopy and conservative treatments only on knee OA were included. Quality of included studies was evaluated by risk of bias 2 (ROB2). Long-term results in terms of pain relief, functional recovery and patients reported satisfaction were meta-analyzed to evaluate the therapeutic effectiveness.

resultsTen studies were included in this review, among which only 1 was considered as low risk of bias. Five studies were involved in meta-analyses and no difference was found in therapeutic effectiveness of arthroscopic surgery and conservative treatment on knee OA, in the evaluation of VAS (p = 0.63), WOMAC (p = 0.38), SF-36 (p = 0.74) and patient satisfaction (p = 0.07).

conclusionThe evidence does not support the effectiveness of arthroscopic knee surgery compared to conservative treatments in knee OA.
