Summary
Patients with diabetes mellitus demonstrate similar and favorable improvements at minimum 2 years after arthroscopic labral treatment when compared to a matched control group without diabetes mellitus.
Abstract
Background
Although diabetes mellitus (DM) and hip arthroscopy have both become increasingly common, the impact of DM on hip arthroscopy outcomes has not been studied. We hypothesized that patients with DM undergoing hip arthroscopy for labral tears have inferior outcomes at a minimum of 2 years postoperatively compared to patients without DM.
Methods
Data were prospectively collected and retrospectively reviewed on patients that underwent hip arthroscopy between February 2008 and December 2014. The inclusion criteria were patients with DM that underwent hip arthroscopy for the treatment of femoro-acetabular impingement (FAI) and labral tears, and had preoperative modified Harris Hip Score (mHHS), Non-Arthritic Hip Score (NAHS), Hip Outcome Score – Sports Specific Subscale (HOS-SSS), and Visual Analogue Scale (VAS). The exclusion criteria were preoperative Tonnis grade > 1, previous hip conditions and/or ipsilateral hip surgery. All patients with DM were matched in a 1:2 ratio to control patients without DM. The matching criteria were age at surgery ± 8 years, gender, BMI ± 5, Worker’s Compensation claim, capsular treatment (release vs. closure), and acetabular Outerbridge grade 0 or 1 vs. 2, 3, or 4.
Results
Of 29 eligible patients with DM, 26 (89.7%) had minimum two-year follow-up. Twenty-six patients with DM were matched and compared to 52 patients without DM. Acetabuloplasty was performed more frequently in the control group (p=0.01). 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, conversion rates to total hip arthroplasty (THA), or complication rates.
Conclusions
Patients with DM demonstrate similar and favorable improvements at a minimum of 2 years after arthroscopic labral treatment when compared to a matched control group without DM. However, the DM group demonstrated a non-statistically significant trend towards inferior outcomes in all PROs, VAS, and satisfaction
