1 · What the graph read from 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.

2 · The registry

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

backgroundBoth high tibial osteotomy (HTO) and unicompartmental knee arthroplasty (UKA) are well-established treatments for medial knee osteoarthritis (OA). However, it is unclear whether HTO or UKA leads to better clinical outcomes and lower complication rates. This meta-analysis compared the clinical outcomes and complications of HTO and UKA in patients with medial knee OA.

methodsAll studies comparing the functional outcome, postoperative pain, revision rate to total knee arthroplasty (TKA), postoperative complications, postoperative velocity, and postoperative range of motion (ROM) as assessed with various measurement tools in patients with medial knee OA treated with HTO or UKA were included.

resultsSixteen studies were included in the meta-analysis. The proportion of patients who underwent revision to TKA (OR 1.56, 95% CI: 0.61-3.98; P = .35) did not differ significantly between HTO and UKA. In contrast, functional outcome (OR 0.47, 95% CI: 0.24 to 0.95; P = .04), postoperative pain (OR 0.28, 95% CI: 0.12 to 0.62; P = .002), postoperative complications (OR 2.48, 95% CI: 1.26 to 4.90; P = .009), postoperative velocity (95% CI: -0.11 to -0.00; P = .03), and postoperative ROM (95% CI: 2.02 to 15.23; P = .01) were significantly different between the 2 groups.

conclusionsThere were no significant differences in the revision rate to TKA between HTO and UKA. However, results from subgroup analyses suggested that opening-wedge HTO resulted in a lower revision rate to TKA than did UKA, whereas closing-wedge HTO resulted in a higher revision rate to TKA than did UKA. In addition, UKA resulted in significantly better functional outcomes and postoperative velocity, along with less postoperative pain, fewer postoperative complications, and lower postoperative ROM. Based on the findings of current meta-analysis, UKA appears to be as efficacious and safe as HTO in the treatment of medial knee OA.
