Impact of Chronic Opioid Use in Recurrent Dislocations following Revision Total Hip Arthroplasty: An Iatrogenic Charcot-Like Arthropathy Case Report.
Article in Hip & pelvis, 2026. 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
The challenging complication of recurrent dislocation following total hip arthroplasty (THA) is often attributed to component malposition, soft tissue imbalance, or spinopelvic pathology. We report a case of intractable recurrent dislocation following revision THA for a periprosthetic femoral fracture in a 91-year-old female. The patient experienced multiple painless dislocations despite performing component revision to enhance stability and confirming acceptable combined anteversion by computed tomography. We performed a comprehensive review of the patient's history and noted chronic, high-dose analgesic use, including the continuous use of a fentanyl patch for three years. Therefore, we hypothesized chronic opioid use contributed to the severe hyposensitivity to pain by eliminating the protective sensory feedback mechanisms essential to joint stability and mimicking the pathophysiology of Charcot arthropathy. Since potent analgesics can mask protective sensation and precipitate iatrogenic Charcot-like arthropathy, our case highlights the necessity to evaluate medication history in elderly patients with unexplained, painless recurrent instability.
