BMI not associated with clinical outcomes after hip arthroscopy

Despite some initial clinical differences, multivariate analysis results published in The American Journal of Sports Medicine showed no associations between BMI and clinical outcomes after hip arthroscopic surgery with capsular plication for femoroacetabular impingement.
“Overall, our data demonstrates that BMI greater than normal range does not appear to have a significant deleterious effect on patient-reported clinical outcomes when controlling for additional confounding variables,” Bryan M. Saltzman, MD, told Healio.com/Orthopedics. “This supports the notion that all patients, irrespective of BMI, could be counseled that they could expect long-term improvements in both pain and function following hip arthroscopy.”
Saltzman and colleagues categorized 381 patients (61% were women) undergoing primary hip arthroscopic surgery for femoroacetabular impingement (FAI) by preoperative BMI into underweight, normal, overweight, obese or morbidly obese groups. Researchers collected hip outcome score-activities of daily living (HOS-ADL), HOS-sports, modified Harris Hip score, VAS for pain, satisfaction and patient acceptable symptomatic state (PASS) for the HOS-ADL preoperatively and at 3 months, 1 year and a minimum of 2 years postoperatively.
Results showed significant differences in the trend among HOS-ADL, HOS-sports and modified Harris Hip scores at 2 years postoperatively, with normal BMI patients demonstrating greater scores vs. patients who were overweight, obese or morbidly obese. Researchers noted lower satisfaction scores among patients who were obese, as well as lower improvements in VAS pain scores among patients who were overweight, obese or morbidly obese. According to results, increasing BMI had an association with higher infection risk.
However, multivariate analysis showed patient clinical outcomes had no significant differences between the BMI categories. Researchers found no specific risk factors to be significantly associated with decreases in the change in VAS, HOS-ADL, HOS-sports, modified Harris Hip score, satisfaction or PASS for the HOS-ADL score among patients who were obese. – by Casey Tingle
