Total knee arthroplasty (TKA) remains the standard for advanced OA, yet up to 20% of patients experience chronic postsurgical pain (CPSP). Genicular nerve radiofrequency ablation (GNRFA) can alleviate pain in those unresponsive to conservative treatments or TKA.

However, biases in AI, arising from sex, race, socioeconomic status (SES), and statistical methods, can exacerbate disparities in pain management. This narrative review examines these biases and proposes strategies to mitigate them. A comprehensive literature search across databases such as PubMed, Google Scholar, and PsycINFO focused on AI applications in pain management and sources of biases. Sex and racial biases often stem from societal stereotypes, underrepresentation of females, overrepresentation of European ancestry patients in clinical trials, and unequal access to treatment caused by systemic racism, leading to inaccurate pain assessments and misrepresentation in clinical data. SES biases reflect differential access to healthcare resources and incomplete data for lower SES individuals, resulting in larger prediction errors. Statistical biases, including sampling and measurement biases, further affect the reliability of AI algorithms. To ensure equitable healthcare delivery, this review recommends employing specific fairness-aware techniques such as reweighting algorithms, adversarial debiasing, and other methods that adjust training data to minimize bias. Additionally, leveraging diverse perspectives-including insights from patients, clinicians, policymakers, and interdisciplinary collaborators-can enhance the development of fair and interpretable AI systems. Continuous monitoring and inclusive collaboration are essential for addressing biases and harnessing AI's potential to improve pain management outcomes across diverse populations.</p>","PeriodicalId":16661,"journal":{"name":"Journal of Pain Research","volume":"18 ","pages":"1021-1033"},"PeriodicalIF":2.5,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11878133/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143557120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most individuals who experience pain after an LAS self-report a moderate pain intensity level that interferes with activity. This pain experience is mostly described through study designs and outcomes that limit the understanding of the acute to chronic pain transition after an LAS. The purpose of this prospective study is to quantify the prevalence rate of chronic ankle pain at 6-months post-injury and identify susceptibility and resiliency factors that contribute to pain chronification after an LAS. The objective of this study will be accomplished through a two-site prospective cohort study design with data collected at four timepoints (<7 days post-LAS, 3-, 6-, and 12-months post-LAS). A target sample size of 200 men or women (100 per site) between 18 and 45 years of age who sustain an acute LAS within the previous 7-days will be enrolled. Participants will complete a series of standardized electronic surveys at each timepoint to self-report the presence of chronic ankle pain, healthcare utilization patterns, subsequent musculoskeletal injury, and new co-morbid conditions. Additionally, participants will complete validated patient-reported outcomes (PROs) electronically to characterize the pain burden and undergo quantitative sensory testing to assess mechanical pain sensitivity via pressure pain thresholds, pain facilitation via temporal summation, and pain inhibition via a conditioned pain modulation response at all timepoints. Lastly, clinician-based outcomes will be completed at 3-, 6-, and 12-months post-LAS to examine dynamic postural control, functional performance, and walking mechanics. We hypothesize that 30% of participants will self-report chronic ankle pain at 6-months post-injury.
