[Postoperative pain therapy after total knee arthroplasty : Is the local infiltration anesthesia the best therapy?]
Article in Schmerz (Berlin, Germany), 2020. 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
backgroundOptimal perioperative pain management after total knee arthroplasty is necessary to promote mobilization and achieve early rehabilitation. The aim of this study was to determine whether local infiltration anesthesia (LIA) is the better postoperative pain therapy compared to a femoral nerve block (FNB) or a sciatic nerve block (SNB) using routine data.
methodsData from the acute pain registry "Qualitätsverbesserung in der postoperativen Schmerztherapie" (QUIPS) were analyzed. The endpoints included postoperative maximal pain, frequency of pain-related movement impairment, nausea, and number of patients requesting opioids postoperatively. The influence of regional anesthesia in addition to general anesthesia was analyzed in 5 groups.
resultsIn total, the data of 8754 patients could be examined. It was found that the addition of LIA (β = -0.087 p = 0.000) or FNB (β = -0.137 p = 0.000) to general anesthesia is associated with a small but significant reduction of postoperative maximum pain. Between LIA, FNB, and SNB no relevant differences could be detected. DISCUSSION: The pain reduction achieved by adding LIA or FNB in patients after total knee arthroplasty is relatively small. Comparison of techniques is hindered as there exists no widely accepted standard for performing LIAs yet.
