The Forced Drop Leg Test: A Novel Intraoperative Technique Enhancing Stability Assessments in Total Hip Arthroplasty.
Article in Journal of orthopaedic case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Introduction: Prosthetic instability remains a major challenge in total hip replacement (THR), which can result in dislocation, reduced mobility, and prosthetic loosening, requiring revision surgery. The forced drop leg test (FDLT) introduces a proactive approach by assessing hip stability under forced flexion, adduction, and rotation mimicking real-world dislocation mechanisms. Technique: Standard exposure and trial implants are utilized to evaluate fit and alignment. With the trial components in place, the leg is abducted to 30-40°, then forcefully dropped into a sterile pouch in front. The hip joint is subsequently examined for dislocation or subluxation. In case of any dislocation or subluxation, reassessment of the component size and position is necessary. Conclusion: Preliminary evidence suggests that FDLT enhances existing stability checks, although broader clinical validation and protocol standardization are necessary to confirm its effectiveness.
