BACKGROUND: Studies on the results of arthroscopic repair of massive rotator cuff tears have reported widely varied prognoses. Among other factors, the sizable discrepancy can be attributable to the fact that the current definition of massive rotator cuff tears covers an extensive area of tendons. HYPOTHESIS: Functional and radiological results according to subgroups would show significant inter-subgroup differences preoperatively and postoperatively. STUDY DESIGN: Cohort study; Level of evidence, 2...

The incidence of arthroscopic rotator cuff repair (RCR) continues to rise. Given the changing healthcare climate, it is becoming increasingly important to critically evaluate current practice and attempt to make modifications that decrease costs without compromising patient outcomes. We conducted a study of the costs associated with arthroscopic anchorless (transosseous [TO]) RCR and those associated with the more commonly performed anchor-based TO-equivalent (TOE) method to determine whether there are any cost savings with the TO-RCR method...

Polyhydroxyalkanoate (PHA) mesh is a bioresorbable scaffold used to reinforce the suture-tendon interface in rotator cuff repairs (RCRs). We conducted a study of cyclic and ultimate failure properties of PHA mesh-augmented single-row RCRs and nonaugmented RCRs. Eight pairs of fresh-frozen cadaver humeri (6 male, 2 female) were tested. Mean (SD) age was 61 (9) years. The supraspinatus tendon was resected and reattached in a single-row configuration using 2 triple-loaded suture anchors and 6 simple stitches. The opposite humerus underwent RCR augmented with 2 strips of 13-mm × 23-mm PHA mesh...

The presentation of anaplastic lymphoma kinase protein (ALK)-negative anaplastic large cell lymphoma (ALCL) in bone is rare. We describe a patient with ALK-negative ALCL presenting with clinical and radiographic findings suggesting osteomyelitis 6 months after left rotator cuff repair surgery. A review of the characteristics of ALK-negative ALCL with primary bone involvement is presented. ALCL should be considered in patients not responding to therapies for osteomyelitis.

An increasing number of orthopaedic surgeries are performed at ambulatory surgical centers (ASCs), as is exemplified by the 272% population-adjusted increase in outpatient rotator cuff repairs from 1996 to 2006. Outpatient surgery is convenient for patients and cost effective for the healthcare system. The rate of complications and adverse events following orthopaedic surgeries at ASCs ranges from 0.05% to 20%. The most common complications are pain and nausea, followed by infection, impaired healing, and bleeding; these are affected by surgical and patient risk factors...

Purpose. To compare the biomechanical properties of 3 suture-bridge techniques for rotator cuff repair. Methods. Twelve pair-matched fresh-frozen shoulder specimens were randomized to 3 groups of different repair types: the medially Knotted Suture Bridge (KSB), the medially Untied Suture Bridge (USB), and the Modified Suture Bridge (MSB). Cyclic loading and load-to-failure test were performed. Parameters of elongation, stiffness, load at failure, and mode of failure were recorded. Results. The MSB technique had the significantly greatest load to failure (515...

BACKGROUND: Fatty degeneration of the cuff muscles is usually evaluated at the Y-view in oblique sagittal images. It was recently proposed that muscle shift after repair may influence the fatty degeneration values, and the evaluation of the muscles at a more medial site was recommended. However, the differences in muscle quality in accord with measurement sites have been unclear. Here we evaluated differences in fatty degeneration of the rotator cuff muscles measured quantitatively at different sites, using T2 mapping...

PURPOSE: To determine the most cost-effective treatment strategy for patients with massive rotator cuff tears and pseudoparalysis of the shoulder without osteoarthritis of the glenohumeral joint (PP without OA). Specifically, we aimed to compare arthroscopic rotator cuff repair (ARCR) versus reverse total shoulder arthroplasty (RTSA) and investigate the effect of patient age on this decision. METHODS: A Markov decision model was used to compare 3 treatment strategies for addressing PP without OA: (1) ARCR with option to arthroscopically revise once, (2) ARCR with immediate conversion to RTSA on potential failure, and (3) primary RTSA...
