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

introductionPosterior hindfoot endoscopy is a safe and effective treatment for posterior ankle impingement syndrome (PAIS). However, data on the outcomes of needle arthroscopy for PAIS in athletes are still lacking. The purpose of this study is to investigate the clinical outcomes and return to sports following hindfoot endoscopic surgery utilizing 1.9-mm-diameter needle arthroscopy in the treatment of PAIS, especially in athletes, including ballet dancers. MATERIALS AND

methodsA retrospective cohort study was conducted to evaluate patients who underwent hindfoot endoscopic surgery using 1.9-mm-diameter needle arthroscopy for PAIS between 2021 and 2023. Clinical outcomes were evaluated preoperatively and 12 months after surgery using the Japanese Society for Surgery of the Foot (JSSF) scale and the Self-Administered Foot Evaluation Questionnaire (SAFE-Q). The time to return to sports training and complete return to sports activities were also evaluated.

resultsThirteen patients (5 males and 8 females) with a mean age of 21.1 years were included. The mean follow-up time was 17.1 months. Sports activities included ballet (7 patients), soccer (3 patients), lacrosse (2 patients), and tennis (1 patient). The mean JSSF scale significantly improved from 79.1 preoperatively to 98.3 at the final follow-up (p < 0.001). The mean SAFE-Q scores improved significantly postoperatively in all subscales, except the shoe-related subscale. The mean time to return to sports-specific training was 3.8 weeks. All patients were able to return to full sports activities, and the mean time to return to full sports activities at the pre-injury levels was 6.3 weeks. The ballet dancers returned to full activity at the pre-injury levels at a mean time of 7.3 weeks.

conclusionsPosterior hindfoot endoscopy employing 1.9-mm-diameter needle arthroscopy demonstrated excellent clinical outcomes in the management of PAIS in this preliminary case series, including ballet dancers who typically require longer recovery periods. While these results suggest potential advantages including earlier return to sports compared to historical controls, further comparative studies with conventional arthroscopy are needed to confirm these findings. LEVEL OF EVIDENCE: Level IV, Case series.
