Diabetes Mellitus Is Not a Negative Prognostic Factor for Patients Undergoing Hip Arthroscopy

Diabetes mellitus (DM) has been associated with inferior clinical outcomes and comorbidities in general. The authors sought to compare the outcomes of hip arthroscopy at minimum 2-year follow-up for patients with DM with those of patients without DM. Data were prospectively collected and retrospectively reviewed for patients who underwent hip arthroscopy between February 2008 and December 2014. The inclusion criteria were patients with DM who underwent hip arthroscopy for the treatment of femoroacetabular impingement and labral tears and had preoperative patient- reported outcomes. The exclusion criteria were preoperative Tönnis grade greater than 1, previous ipsilateral hip surgery, and/or previous conditions. All patients with DM were matched in a 1:2 ratio to control patients without DM. The matching criteria were age at surgery, sex, body mass index, workers' compensation, capsular treatment, and acetabular Outerbridge grade 0 or 1 vs 2, 3, or 4. Of 29 eligible patients with DM, 26 (89.7%) had minimum 2-year follow-up. Twenty-six patients with DM were matched and compared with 52 patients without DM. Acetabuloplasty was performed more frequently in the control group (P=.01). There were no other statistically significant differences detected in terms of demographics, preoperative radiographic imaging, intraoperative findings, procedures, preoperative scores, follow-up scores, revision rates, rates of conversion to total hip arthroplasty, or complication rates. Patients with DM demonstrated favorable improvements at 2 or more years after arthroscopic labral treatment when compared with a matched control group without DM. The DM group demonstrated a non-statistically significant trend toward inferior outcomes in all patient-reported outcomes, visual analog scale score, and satisfaction.
