Popis: The purpose of this retrospective study was to report on the functional outcome after both open and arthroscopic rotator cuff (RC) repair in normal weight, pre-obese and obese patients. It was hypothesized that obesity is a negative prognostic factor for clinical outcome and failure for the RC repair. One hundred and forty-six patients who underwent either open or arthroscopic rotator cuff repair between 2006 and 2010 were included in this study. Seventy-five patients (56.7 ± 10.1 years of age) after open RC repair and 71 patients (59.0 ± 9.1 years of age) treated arthroscopically were available for evaluation. In both groups a double-row reconstruction was performed. Patients were divided in three groups according to their body-mass index. The mean follow-up was at 43 ± 16 (minimum 24) months. At follow-up, the clinical outcome was assessed by the DASH and Constant score. An ultrasound of both shoulders was performed in all patients. The mean BMI was 28.3 ± 5.3 in the arthroscopic group and 27.7 ± 4.3 in the open group. Overall, in both groups similar clinical results were noted [Constant–Murley score 78.3 ± 18.2 arthroscopic vs. 77.0 ± 21.8 for open surgery; DASH 12.7 ± 18.2 arthroscopic vs. 15.6 ± 21.6 for open surgery (p = 0.81)]. Both the failure rate and the clinical outcome were significantly worse for obese patients (BMI > 30, p = 0.007). The failure rate was 15.8% for the normal-weight patients, 8.2% in the pre-obese group and in the obese group 28.6%. The RC repair failure occurred in 11 cases in both groups after arthroscopic or open treatment (15.0%). Both the arthroscopic and the open approach showed equivalent clinical results and failure rates. Obesity (BMI > 30) causes less favorable results in the Constant and DASH scores and showed higher re-tear rates.
