Efficacy of interspace between the popliteal artery and the capsule of the posterior knee (iPACK) block versus periarticular local infiltration analgesia after unilateral total knee arthroplasty: Prospective randomized control trial.
Trial report in Saudi medical journal, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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
objectivesTo compare the efficacy of interspace between the popliteal artery and the capsule of the posterior knee (iPACK) block with periarticular local infiltration analgesia (LIA) to assess postoperative pain control and enhanced recovery after total knee arthroplasty (TKA).
methodsThis research was carried out at King Saud University Medical City, Riyadh, Saudi Arabia, from September 2020 to March 2021. Eighty Patients scheduled for elective unilateral TKA were randomized to receive either iPACK or periarticular LIA along with adductor canal block under spinal anesthesia. The primary outcome was postoperative pain score, and secondary outcomes included physical rehabilitation, duration of surgery, length of post-anesthesia care unit stay, hemodynamics, and length of hospital stay.
resultsThe pain score during activity in iPACK group was significantly lower compared to LIA group at 4 hours postoperatively, but no significant difference was observed at 24 or 48 hours. The timed up and go test took significantly longer for patients in LIA group at 4, 24, and 48 hours compared to those in iPACK group. No significant differences in knee range of motion were observed between the 2 groups at any point.
conclusionBased on our findings, iPACK block is an effective technique in reducing pain in the immediate postoperative period without affecting motor function, resulting in enhanced recovery following primary TKA.
