Description
Summary:Purpose Acute traumatic and chronic non-traumatic rotator cuff tears are etiologically distinguishable entities. However, prospective studies comparing tear characteristics and outcomes between these two types of tears are lacking. The purpose of this study was to compare the tear characteristics, clinical and functional outcomes, and tendon healing as assessed on magnetic resonance imaging (MRI), between traumatic and non-traumatic rotator cuff tears. Methods MRI proven rotator cuff tears were allocated into two groups according to the history of injury: Group 1 included 28 patients with traumatic tears and group 2 included 33 patients of non-traumatic cuff tears. Both the groups were compared for preoperative tear characteristics (tear size, muscle atrophy, fatty degeneration), range of motion, strength of shoulder abduction and external rotation, functional outcomes, and tendon integrity on MRI, 2 years after the surgery. Results Postoperative mean active range of abduction ( p  = 0.005), abduction strength ( p  = 0.013), external rotation strength ( p  = 0.027), University of California at Los Angeles score ( p
