Complications Within 6 Months After Arthroscopic Rotator Cuff Repair: Registry-Based Evaluation According to a Core Event Set and Severity Grading

[摘要] Purpose: To report complications after arthroscopic rotator cuff repairs (ARCRs) in a large patient cohort based on clinical application of a newly defined core event set (CES) and severity grading. Methods: Consecutive primaryARCRs documented in a local clinical registry between February 2010 and September 2016 were included. Clinicians documented adverse events (AEs) reported until the final, 6-month postoperative follow-up according to the CES. The CES is an organized list of relevant AEs sorted into 3 intraoperative event groups (device, osteochondral, and soft tissue) and 9 postoperative event groups (device, osteochondral, pain, rotator cuff, surgical-site infection, peripheral neurologic, vascular, superficial soft tissue, and deep soft tissue). Severity was determined using an adaptation of the Clavien-Dindo classification. Cumulative complication risks were calculated per event group and stratified by severity and rotator cuff tear extent. Results: A total of 1,661 repairs were documented in 1,594 patients (mean age, 57 years [standard deviation, 9 years]; 38% women); 21% involved partial tears. All events were recorded according to the CES. Intraoperative events occurred in 2.2% of repairs. Weidentified 329 postoperative events in 307 repairs (305 patients); 93% had 1 AE. The cumulative AE risk at 6 months was 18.5%; AE risks were 21.8% for partial tears, 15.8% for full-thickness single-tendon tears, 18.0% for tearswith 2 ruptured tendons, and 25.6% for tears with 3 ruptured tendons. AE risks per event group were as follows: 9.4% for deep soft tissue, with shoulder stiffness (7.6%) being the most common event; 3.4% for persistent orworsening pain; 3.1% for rotator cuff defects; 1.7% for neurologic lesions; 0.8% for surgical-site infection; 0.7% for device; 0.4% for osteochondral; 0.2% for superficial soft tissue, and 0.1% for vascular. Most AEs had severity grades I (160 [49%]) and II (117 [36%]). Conclusions: Comprehensive local AE documentation according to the CES and severity grading was possible and showed that about one-fifth ofARCRs were affected, mostly by one AE of low severity. Shoulder stiffness was the most frequent event.
