Ateschrang A, et al. - Experts reported the functional outcome after both open and arthroscopic rotator cuff (RC) repair in normal weight, pre-obese and obese patients, presuming that obesity was a negative prognostic factor for clinical outcome and failure for the RC repair. Equivalent clinical results and failure rates were demonstrated by both the arthroscopic and the open approach. In the Constant and DASH scores, obesity (BMI > 30) was seen to cause less favorable results and it showed higher re-tear rates. For the normal-weight patients, the failure rate was 15.8%, in the pre-obese group it was 8.2% and in the obese group 28.6%.
