Do patient personality traits influence total joint arthroplasty outcomes? A systematic review.

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
Background: Outcomes after total joint arthroplasty are influenced by various biopsychosocial factors, among which preoperative psychological status and personality traits play a crucial role. Given that personality traits - such as extroversion, psychoticism, anxiety, and neuroticism - represent a wider, enduring framework compared to transient mental states like depression and stress, their impact on surgical outcomes is significant. This systematic review aims to evaluate the influence of personality traits on clinical outcomes after total joint arthroplasty. Methods: PubMed, Web of Science, Scopus, and Embase were explored from initiation until May 2025. The inclusion terms were "personality traits," "total knee arthroplasty," and "total hip arthroplasty," along with related MeSH terms, with no boundaries for language. Backward reference citation searches were also conducted. Results: Finally, a total of 15 studies were included. Anxiety is one of the most substantial factors impacting the consequences of total joint arthroplasty. Although there is unsatisfactory evidence supporting pain reduction in extroverted individuals, extroversion has been associated with improved quality of life and postoperative functional outcomes. Additionally, neuroticism has a negative correlation with quality of life and is linked to increased pain levels. Pessimism is associated with greater pain, reduced knee function improvement, and increased activity limitations. Based on quality-of-life questionnaires, extroversion and melancholic traits were associated with higher scores. However, neuroticism showed a negative correlation with Short Form (SF)-36 scores. Conclusions: Pain was the most significant assessed outcome. A positive association was observed between pain and traits such as extroversion, neuroticism, pessimism, anxiety, depression, and persistence. Concerning quality of life, features like extroversion and melancholic temperament were associated with higher quality of life, whereas neuroticism had a negative correlation with SF-36. Based on these findings, considering personality and psychological factors can contribute to improving surgical outcomes, and preoperative counseling is recommended.
