The Impact of Preoperative Inflammatory Activity in Patients with Ankylosing Spondylitis on Postoperative Joint Function: A Retrospective Cohort Study

These findings suggest that elevated preoperative inflammatory markers, particularly ESR, are not contraindications for THA in AS patients. Instead, they may indicate a greater capacity for postoperative functional recovery. The study supports a proactive surgical approach in appropriately selected AS patients, emphasizing the need for individualized assessment and consideration of systemic inflammation as a potential marker of postoperative improvement rather than a barrier to surgical intervention. These insights could refine surgical decision-making and optimize timing for THA in AS patients.
