Rotator cuff tears are a major cause of morbidity. Following rotator cuff tears, muscle atrophy and fatty infiltration begin in the tissue, limiting repair potential and leading to a higher re-tear rate and a worse functional outcome. We evaluated whether fatty degeneration resulting from a complete supraspinatus tear with retraction is associated with an injury to the suprascapular nerve. Four...

BACKGROUND Arthroscopic rotator cuff repair has become popular in the last few years because it avoids large skin incisions and deltoid detachment and dysfunction. Earlier arthroscopic single-row (SR) repair methods achieved only partial restoration of the original footprint of the tendons of the rotator cuff, while double-row (DR) repair methods presented many biomechanical advantages and high...

With a range of tear characteristics such as chronicity, degree of fatty atrophy, and number of tendons involved as well as varying patient-specific characteristics including age, injury mechanism, and expectations after treatment to consider, proper and successful treatment of a rotator cuff tear is multifactorial and, consequently, challenging. Although conservative management of a rotator cu...

We have used Fourier transform infrared spectroscopy (FTIR) to characterise the chemical and structural composition of the tendons of the rotator cuff and to identify structural differences among anatomically distinct tears. Such information may help to identify biomarkers of tears and to provide insight into the rates of healing of different sizes of tear. The infrared spectra of 81 partial, s...

The prevalence of partial rotator cuff tears (PRCTs) is high in the general population. Our hypothesis that barbotage, when associated with platelet-rich plasma (PRP), an effective method for healing these tears. aim this study was to compare effects barbotage or without PRP on supraspinatus tendon (PSTTs). This assessed Western Ontario Rotator Cuff Index score and ultrasound (US) images at 6 w...

The long head of biceps tendon (LHBT) is frequently involved in rotator cuff tears and can cause anterior shoulder pain. Tendon hypertrophy, hourglass contracture, delamination, tears, and tendon instability in the bicipital groove are common macroscopic pathologic findings affecting the LHBT in the presence of rotator cuff tears. Failure to address LHBT disorders in the setting of rotator cuff...

Babaei-Ghazani A, Eftekhar-Sadat B, Ghabili K: Simultaneous bilateral biceps tendon rupture: a case report with practical sonographic diagnosis. Am J Phys Med Rehabil 2015;94:e13Ye18. Simultaneous bilateral complete tear of the biceps tendons is a rare clinical entity with challenging treatment approaches. Current diagnostic imaging of rupture of the biceps tendon has reverted to magnetic reson...

Subscapularis tendon tears present a technical challenge because both diagnosis and arthroscopic treatment can be difficult. One difficulty is the limited visualization and working space of the anterior shoulder. Although most tears of the subscapularis are partial- or full-thickness tears of the upper third of the tendon, occasionally, larger or more retracted tears are encountered. Various te...

INTRODUCTION: The clinical outcomes of rotator cuff repair vary among patients and are affected by multiple factors including chronic inflammation. Although inflamed synovium is a common clinical observation at the time of surgery, the role of this inflammation plays on clinical outcomes is not well elucidated. Several recent studies have shown that there is elevation of pro-inflammatory cytoki...
