Postoperative footdrop following total hip arthroplasty: Epidemiology, risk factors, and associated complications.

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
Background: Footdrop is a relatively uncommon complication following total hip arthroplasty (THA) caused by injury to the sciatic and peroneal nerve. Few studies have evaluated the risk factors or trends for the development of this challenging complication. As such, this study aims to describe the epidemiology, procedural risk factors, and related complications of postoperative footdrop following THA. Methods: Adult primary or revision THA patients were identified using the PearlDiver database. Eligible patients were filtered into cohorts based on the development of footdrop within 90 days of surgery and matched 1:1 by age, sex, and comorbidities. Epidemiological trends in footdrop were evaluated by age and year between 2010 and 2022. Patient demographics, comorbidities, procedural characteristics, hospital outcomes, and occurrence of intra- and post-operative complications were compared. Results: In total, 2282 footdrop (0.3 %) and 893,159 (99.8 %) no footdrop THA patients were included, with a mean age of 64.9 years and 56.2 % were women. The incidence of footdrop decreased from 0.3 % to 0.2 % between 2010 and 2022 and was not associated with age. Preoperatively, footdrop patients more frequently underwent revision THA (Footdrop = 12.3 % vs No footdrop = 5.7 %, Conclusion: Patients developing footdrop following THA were more likely to be women, undergoing revision surgery, and had higher rates of prior lumbar fusion and medical comorbidities. They reported more postoperative complications and subsequent revisions following THA. This study informs us of the risk factors footdrop and may contribute to better patient counseling and surgical planning before undergoing THA.
