Background & Aims
Detecting predictors influencing the choice between surgical intervention and conservative treatment in hip osteoarthritis is crucial. Unraveling these factors is vital for tailored patient care. This prospective cohort study aimed to investigate the influence of pain, psychosocial and psychophysical features, and hip disability factors on patients’ decision to undergo hip replacement surgery for unilateral hip osteoarthritis.
Methods
Subjects aging over 18 with unilateral painful hip osteoarthritis were selected through medical history, clinical examination, and hip X-ray imaging. Pain, hip disability, psychosocial, and psychophysical parameters, were assessed using Visual Analogic Scale (VAS), Harris Hip Score (HHS), Pain Catastrophizing Scale (PCS), Pressure Pain Threshold (PPT), and Conditioned Pain Modulation (CPM). Patients were evaluated at inclusion and after a one-month conservative treatment which comprised medications, exercises, and physiotherapy. Patients were asked about their satisfaction with conservative treatment, and dissatisfied individuals were offered the option of hip surgery. Based on their decision, patients were categorized into Non-Surgical and Surgical groups for statistical analysis. T-tests, chi-squared tests, and two-way repeated measures ANOVA compared groups. Binomial logistic regression analyzed the probability of opting for surgical treatment.
Results
Fifty-one subjects with unilateral hip osteoarthritis were evaluated. No dropouts occurred. Significant differences were observed between surgical and non-surgical groups for coxarthrosis degree, pain duration, PCS, and HHS (p<0.05). Patients opting for surgery had higher pain, psychosocial and hip impairment. The logistic regression model explained 59.1% of variance and identified HHS and higher pain levels during Flexion, Adduction, Internal Rotation (FADIR) test as significant predictors for the decision to undergo surgery. Specifically, an increase in FADIR pain levels is correlated with a heightened probability of opting for hip surgery.
Conclusions
In conclusion, this study offers valuable insights into the multifaceted factors influencing patients’ choices for hip replacement surgery. Emphasizing the importance of a comprehensive assessment, including psychosocial evaluation, is pivotal. Furthermore, our findings underscore the significance of pain levels during passive movements and the degree of joint disability as critical influencers in the decision-making process regarding surgical intervention. These considerations contribute significantly to the overall understanding of factors guiding clinical decisions and ultimately improving patient care in hip osteoarthritis management.
