Introduction
This study aimed to examine the effects of body mass index (BMI) on functional recovery after total hip arthroplasty (THA).
Materials and methods
This prospective case-control study included 269 patients who underwent primary THA. Participants were categorized into normal weight, overweight, and obese groups based on the World Health Organization criteria. Recovery outcomes were assessed across BMI groups using gait measurements and the Japanese Orthopaedic Association (JOA) hip scores.
Results
Patients with obesity exhibited slower recovery in walking speed and stride length at 6 months and 1 year than did their less-obese counterparts. At 1 year post-surgery, the JOA hip scores showed no significant differences among the BMI groups, thereby indicating similar satisfaction levels despite initial functional recovery differences.
Conclusions
Although patients with obesity faced early recovery challenges, particularly regarding gait, satisfaction with THA outcomes was comparable across all BMI groups at 1 year. These findings highlight the need for personalized management and rehabilitation strategies for optimizing THA outcomes for patients with obesity.
