“…In our study, the prevalence of rerupture among all supraspinatus tendon tears was 46% for the entire series but only 26.9% among small-to-intermediate supraspinatus tendon tears. This is in agreement with reported rerupture prevalences in similar MR-based investigations [18,23]. Intraoperatively torn tendons e Three infraspinatus tendon tears are excluded in this section * Statistical difference of rerupture prevalence between patients with favorable and unfavorable outcome **Statistical difference of rerupture prevalence between non-massive and massive tears ***Statistical difference of rerupture prevalence between SS tear and SS/IS tear ****Statistical difference of rerupture prevalence between SS tear and SB/SS/IS tear The number of torn tendons is said to influence the rerupture prevalence [3,9,10,21].…”

“…Tendon rerupture has attracted preferential attention and has been extensively assessed by means of arthrography [2][3][4][5], ultrasound [6][7][8][9][10][11][12][13][14][15], arthrography combined with computed tomography (CT) [16][17][18], magnetic resonance (MR) imaging [13,[16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33], and MR arthrography [34].…”

MR assessment of the repaired rotator cuff: prevalence, size, location, and clinical relevance of tendon rerupture

The objectives of this study were to use magnetic resonance (MR) imaging to evaluate the prevalence, size, location, and clinical relevance of tendon rerupture following complete repair of full-thickness rotator cuff tear (RCT). A total of 78 surgically proven full-thickness rotator cuff tears in 74 patients were retrospectively included in the study. Clinical assessment was performed using the University of California at Los Angeles score. Postoperative MR imaging was evaluated to determine prevalence, size, and location of tendon rerupture. At a mean 48.4 months' follow-up, 62 shoulders (79.5%) had favorable outcomes and 45 shoulders (57.6%) showed rerupture on MR imaging studies. Reruptures were significantly more prevalent among patients with intermediate-to-bad outcomes (81.3%), with surgically demonstrated two-tendon tears (78.9%) or three-tendon tears (100%), and with preoperative fatty degeneration of the supraspinatus muscle greater than 1 (91.6%). Reruptures were also significantly larger in those subgroups. Complete repair of RCT of all sizes may have favorable outcomes in a significant proportion of patients in spite of a high prevalence of reruptures. Preoperative tear size and degree of muscle fatty degeneration influence the prevalence and rerupture size. After repair of supraspinatus tears, reruptures tend to invade the posterior aspect of the tendon.

“…Thus, if rotator cuff repair was performed, not the normal but the abnormal MR appearance of tendons is the expected finding. Even reduced tendon thickness and partial or full-thickness tendon "tears" can be observed as a "normal" finding in asymptomatic patients, who have undergone rotator cuff surgery with a favorable functional outcome [6,50,51]. In the study by Zanetti and coworkers, full-thickness defects were, however, significantly smaller in asymptomatic patients (<11 mm) than in symptomatic patients [6].…”

Multimodality imaging of the postoperative shoulder

Multimodality imaging of the postoperative shoulder includes radiography, magnetic resonance (MR) imaging, MR arthrography, computed tomography (CT), CT arthrography, and ultrasound. Target-oriented evaluation of the postoperative shoulder necessitates familiarity with surgical techniques, their typical complications and sources of failure, knowledge of normal and abnormal postoperative findings, awareness of the advantages and weaknesses with the different radiologic techniques, and clinical information on current symptoms and function. This article reviews the most commonly used surgical procedures for treatment of anterior glenohumeral instability, lesions of the labral-bicipital complex, subacromial impingement, and rotator cuff lesions and highlights the significance of imaging findings with a view to detection of recurrent lesions and postoperative complications in a multimodality approach.

Purpose:We wanted to evaluate the relationship between the clinical outcomes and cuff integrity after open rotator cuff repair and we wanted to analyze the causes of rotator cuff retear. Materials and Methods: 78 patients who underwent open rotator cuff repair were enrolled from 2004 to 2006. All the patients were observed for a minimum follow-up of 12 months and they were evaluated by magnetic resonance imaging (MRI). The clinical outcomes were accessed by dividing the patients into the retear group and the intact group. The groups were also compared to analyze the cause of rotator cuff retear according to the preoperative tear size, the symptom duration, and so on. Results:The clinical outcome of the retear group (n=22) was improved significantly after operation (p<0.001, p<0.001), but the muscle power was not improved significantly (p=0.099, p=0.243). More retears were found in the patients who had a larger preoperative tear (p<0.001) and the symptom duration of the retear group was longer (p=0.027). Conclusion: Although there were retear after rotator cuff repair, the clinical outcomes were improved. Yet the muscle power of the supraspinatus and external rotator were not improved significantly. There were more retears for the cases that had a larger preoperative tear size and a longer duration of symptoms.
