Does obesity affect outcomes after hip arthroscopy? A cohort analysis.

Abstract: Obesity presents a challenging problem in surgical treatment and has led to poorer postoperative outcomes. The purpose of this study was to evaluate whether hip arthroscopy in the obese patient influences postoperative clinical and patient-reported outcome scores.

METHODS: From February 2008 to February 2012, data were collected prospectively on all patients undergoing primary hip arthroscopy. A total of 680 patients were included. All patients were assessed preoperatively and postoperatively with four patient-reported outcome measures. Pain was estimated on the visual analog scale. The patient satisfaction score was measured. Three groups were stratified by body mass index. The non-obese group, those with a body mass index of <30 kg/m(2) (mean, 23.61 kg/m(2)), included 562 patients with a mean age of 34.78 years. The class-I obese group, those with a body mass index of ≥30 to 34.9 kg/m(2) (mean, 33.85 kg/m(2)), included ninety-four patients with a mean age of 44.02 years. The class-II obese group, those with a body mass index of ≥35 to 39.9 kg/m(2) (mean, 39.11 kg/m(2)), included twenty-four patients with a mean age of 39.33 years.
