Clinical signs and symptoms of chronic periprosthetic joint infection in the hip and knee: a systematic review and meta-analysis.
Synthesis in Archives of orthopaedic and trauma surgery, 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
purposethe diagnosis of prosthetic joint infection (PJI) as a serious complication after total hip and knee arthroplasty is important; however, current criteria lack a universal definition and often exclude key clinical symptoms. This study evaluates the prevalence of clinical signs and symptoms of chronic hip and knee PJI to provide a descriptive map of clinical presentation.
methodsWe conducted a systematic search of Medline, Embase, Web of Science and Scopus to identify studies reporting the prevalence of clinical signs and symptoms in chronic hip or knee PJI published up to June 29, 2024. Statistical analysis was conducted in STATA 17.0 to calculate pooled prevalence and assess heterogeneity. Risk of bias was evaluated using the Joanna Briggs Institute tool. Meta-regression based on the PJI sample size was performed, and a corresponding bubble plot was generated.
resultsOf the initial 3,081 records, 2,360 were excluded during title and abstract screening, and 721 articles underwent full-text screening to minimize the exclusion of relevant studies. Ultimately, 26 cohort studies met the inclusion criteria, comprising 2,350 cases. The criteria used to define PJI varied among studies, with the Musculoskeletal Infection Society (MSIS) criteria being the most commonly used. Meta-analysis showed that 38.1% of patients had fever, 24.7% had a fistula or sinus tract, 85.5% reported pain, 62.1% showed local inflammation, and 49.3% had swelling. Subgroup analysis based on the joint and microorganisms involved reduced heterogeneity levels.
conclusionWe concluded that pain, local inflammatory signs, along fever are the most prevalent symptoms of chronic periprosthetic joint infection in the hip and knee. High heterogeneity in several symptoms indicates the pooled prevalence should be interpreted with caution.
