Osteotomies around the knee are not correlated to substantial post-operative ankle pain.

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
purposeThe relationship between osteotomies around the knee and ankle alignment has been well established. However, little is known about the incidence of new-onset ankle pain after knee osteotomies in the setting of both varus and valgus lower limb malalignments. The purpose of this study is to determine the incidence and characteristics of ankle pain after knee osteotomies; and to clarify the relationship between knee alignment correction, coronal changes suffered by the ankle joint and the development of new-onset ankle pain.
methodsFifty-four lower limbs in 51 consecutive patients, who underwent realignment osteotomies around the knee between April 2013 and October 2020, were retrospectively reviewed. Ultimately, 39 patients (42 knees) were enrolled: 34 had varus deformities and eight had valgus deformities. Ankle pain was assessed according to the Numerical Pain Rating Scale by telephonic interview. The magnitude of alignment correction and the consequent change of both knee and ankle joint lines were analyzed. Correlation between the former and the onset of post-operative ankle pain was evaluated. Patient satisfaction and complications were also noted.
resultsThe incidence of new-onset ankle pain after knee realignment osteotomy was 14%, at a mean follow-up of 55 ± 26 months (range 12-93 months). The mean time between osteotomy and onset of ankle pain was 21 ± 25 months (range 2-60 months). The degree of coronal correction was significantly correlated with ankle joint obliquity changes. However, a significant correlation with post-operative ankle pain was not found (p > 0.05).
conclusionFourteen percent of the patients who underwent osteotomies around the knee developed new-onset persistent low-intensity ankle pain. The knee and ankle joint biomechanics are closely related, however, only a small percentage of patients suffer from low-intensity ankle pain which is successfully managed with occasional analgesics. Most osteotomies around the knee seem to require no particular concern for the ipsilateral ankle function.
