Post-traumatic growth trajectories and influencing factors in patients undergoing hip and knee arthroplasty: a prospective longitudinal study

The PTG scores in THA/TKA patients demonstrated a curvilinear upward trajectory over time, maintaining moderate to low overall levels. Notably, the 1-month postoperative period emerged as a critical window for targeted interventions. Joint function, self-efficacy, proactive coping strategies, and social support significantly enhanced PTG levels, whereas yield-avoidant coping strategies showed negative correlations with PTG scores. Healthcare providers should monitor multidimensional factors influencing PTG variations across different time points, formulating evidence-based health education programs and personalized interventions to accelerate rehabilitation processes.
