No superior method for analgesia after total knee arthroplasty: randomised controlled comparison of adductor canal block combined with iPACK block versus posterior capsule block.
Trial report in Archives of orthopaedic and trauma surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveThe aim of this study compare the effectiveness of the space between the popliteal artery and the posterior knee capsule (iPACK) and posterior capsule injection (PCI) in patients with primary end stage knee osteoarthritis treated with total knee arthroplasty (TKA).
methodsThis was a double-blind, prospective, randomised trial. A total of 195 participants were randomly assigned to one of three groups: Group 1 with an adductor canal block (ACB) plus iPACK. Group 2 with ACB + PCI and a final control group with ACB only. All participants underwent primary total knee arthroplasty. Outcome measures comprised pain assessment using the Visual Analog Scale (VAS) and monitoring opioid analgesic consumption. VAS measurements were taken at the 1st, 6th, 12th, 24th, 48th, and 72nd hours, followed by the 10th day and the 12th week.
resultsAge, sex, BMI and side of surgery were analyzed and no significant differences were found. Groups ACB + iPACK and ACB + PCI exhibited significantly lower VAS scores compared to the control group at 3, 6, and 12 h after surgery, with group ACB + iPACK showing the lowest VAS scores among all groups. No significant difference in VAS values between groups was detected after 24 h postoperatively and after that. Significant differences were observed between groups in opioid consumption. The values for the first hour, first day, second day, and total consumption exhibited statistically significant differences between the groups.
conclusionOur study has shown that PCI in combination with ACB is not inferior to the iPACK technique. It is our belief that these combination techniques can be used in accordance with the surgeon's experience and preference. It is important to remember that PCI is quicker and easier to perform without using ultrasonography.
