Direct visualization-guided PENG block (Pericapsular nerve Group): optimizing postoperative analgesia in total hip arthroplasty.
Article in Journal of orthopaedic surgery and research, 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 pericapsular nerve group (PENG) block has proven to be an effective strategy for postoperative pain management in total hip arthroplasty (THA). However, its implementation requires specialized equipment and expertise, which limits its reproducibility. The objective of this study was to describe the technique of direct visualization-guided PENG block (PENG-DV) and assess its outcomes for postoperative pain control.
methodsA retrospective cohort study was conducted in patients who underwent THA through a direct anterior approach (DAA) and received the PENG-DV block as part of a standardized multimodal analgesia protocol. Demographic variables, pain score on the visual analogue scale (VAS), opioid consumption, muscle strength, and ambulation within the first 24 h were evaluated.
resultsOf the 128 patients identified, 112 were included in the analysis. The cohort was predominantly female (60.7%), with a mean age of 63 years. The median postoperative VAS score was 2 and 3 at 12 and 24 h respectively, increasing to 5 during physical therapy. By postoperative day one, 83.9% of patients ambulated, and most achieved muscle strength ≥ 3 for both hip flexion and knee extension. A total of 54.5% of patients required opioid rescue, with a mean morphine equivalent consumption of 10 mg within the first 24 h.
conclusionPENG-DV for THA via DAA appears to be a promising strategy for effective pain control in the immediate postoperative period, as part of a multimodal analgesic approach designed to reduce opioid consumption and promote early mobilization.
