|Study: Predicting Outcomes of Arthroscopic Rotator Cuff Repair
A study published online in The American Journal of Sports Medicine used predictive modeling to determine which patients were the best candidates for arthroscopic rotator cuff repair (ARCR). The following predictors of functional outcomes after ARCR were included in each model: age, sex, workers’ compensation (WC) status, previous cuff repair, tear size, tear shape, multiple-tendon involvement, tendon stump length, Goutallier classification, critical shoulder angle, length of follow-up, and baseline subjective outcomes score. Postoperative American Shoulder and Elbow Surgeons (ASES); 12-Item Short Form Health Survey Physical Component Summary (SF-12 PCS); and Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) scores, as well as patient satisfaction, were considered. A total of 449 shoulders had a minimum of two-year postoperative patient-reported outcomes (PROs) at a mean 4.8 years. ASES score significantly improved from pre- (58.0) to postoperatively (98.3). At two years, women were significantly more likely to undergo reoperation than men (5.8 percent versus 1.8 percent). Significant independent predictors of lower postoperative ASES scores were previous ARCR, female sex, and a WC claim. Significant predictors of worse QuickDASH scores were a WC claim, female sex, previous ARCR, and at least seven years of follow-up. Significant predictors for lower SF-12 PCS scores were a WC claim, female sex, and lower baseline SF-12 PCS. Significant independent predictors of patient satisfaction were previous ARCR, a WC claim, female sex, and age.
