“…Several overlapping systematic reviews and meta-analyses examined predictors of retears and worse outcomes after RC repair. ∥ Predictors of retears included older age, 52,106,133,144,190 smoking, 196 increased tear size, 52,106,133,144,175,190 additional biceps or acromioclavicular procedures, 52,106 preoperative fatty infiltration, 52,93,133,175 multiple tendon involvement, 52,175 diabetes, 175 DR repairs, 175 increased retraction of the tendon, 52 and decreased bone mineral density. 52 Predictors of worse outcomes included older age, 52 female sex, 52 smoking, 17,196 diabetes, 52 lower baseline scores, 190 workers’ compensation status, 92,106,175,190 decreased preoperative muscle strength, 52,175 increased tear size, 52 preoperative fatty infiltration, 93 <3 months between injury and surgery, 143 decreased sports activity, 52 preoperative shoulder stiffness, 52 and obesity.…”
