The efficacy and safety of subcutaneous continuous local infiltration analgesia with ropivacaine in patients undergoing total knee arthroplasty: a comparative study.
Article in BMC musculoskeletal disorders, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundContinuous local infiltration analgesia (CLIA) can be administered via intraarticular or periarticular techniques in patients undergoing total knee arthroplasty (TKA). The purpose of this investigation was to retrospectively report a single-center experience of epidural analgesia with subcutaneous CLIA versus epidural analgesia without CLIA among patients undergoing TKA.
methodsThis single-center retrospective study was conducted in Saudi Arabia. From January 01, 2014, to December 30, 2020, medical records of all patients who underwent TKA were reviewed. Patients who received subcutaneous CLIA with epidural analgesia were assigned to the intervention group, whereas those who received epidural analgesia without subcutaneous CLIA were assigned to the control group. The efficacy endpoints included: (i) postoperative pain scores at 24 h, 48 h, 72 h, and 3 months; (ii) postoperative opioid consumption at 24 h, 48 h, 72 h, and 24-72 h (cumulative); (iii) length of hospital stay; and (iv) postoperative functional recovery of the knee 3 months post-operation, according to the Knee Injury and Osteoarthritis Outcome Score.
resultsAt rest and during mobilization, the CLIA group (n = 28) achieved significantly lower postoperative pain scores 24 h, 48 h, 72 h, and 3 months post-operation than the non-CLIA group (n = 35). Subgroup analysis revealed that the CLIA group achieved significantly less opioid consumption 24 h and 48 h post-operation than the non-CLIA group. There was no difference between the groups regarding the length of hospital stay or functional scores 3 months post-operation. There was no significant difference between the groups regarding the rate of wound infection, other infections, and readmission within 30 days.
conclusionSubcutaneous CLIA is a technically feasible and safe procedure without major adverse events but with reduced postoperative pain scores (at rest and during mobilization) and opioid consumption. Additional larger studies are warranted to confirm our results. Moreover, a head-to-head comparison between subcutaneous CLIA and periarticular or intraarticular CLIA is an interesting prospective investigation.
