Pseudotumor in Ceramic-on-Ceramic Total Hip Arthroplasty: A Case Report.
Article in Cureus, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Pseudotumors are a rare complication of total hip arthroplasty (THA), arising from local soft tissue reactions. These reactions can lead to painful joint effusions and prosthetic loosening, often necessitating revision surgery. Metal-on-metal and metal-on-polyethylene prostheses are particularly prone to this complication due to the accumulation of metal debris from prosthetic wear, which represents a significant drawback. In contrast, ceramic-on-ceramic (CoC) prostheses are considered a superior alternative, offering lower wear rates and avoiding complications related to metal debris. This case report presents a rare instance of pseudotumor formation in a CoC THA. A 57-year-old patient underwent a cementless CoC THA in 2010. Despite developing a pulmonary embolism, the patient experienced no prosthetic-related complications until 2021, when they presented to the Royal Orthopaedic Hospital with concerns about a deep vein thrombosis. MRI and ultrasound scans of the hip revealed a complex collection involving the iliopsoas bursa and a small joint effusion, prompting a biopsy. Histopathology confirmed a pseudotumor with tissue necrosis, macrophages, neutrophils, and ceramic debris. In 2024, the patient underwent revision arthroplasty with excision of the pseudotumor. The original prosthesis was well-fixed, with minimal damage to the ceramic head and acetabular liner, and there were no signs of infection or metallosis. Following the revision, the patient's pain resolved, and they were satisfied with the outcome of the surgery.
