In this surgical technique, we aimed to describe our preferred method that anatomically repairs both layers of delaminated rotator cuff tear separately in a knotless transosseous equivalent manner.

BACKGROUND Fatty degeneration of the rotator cuff muscles may have detrimental effects on both anatomical and functional outcomes following shoulder surgery. The purpose of this study was to investigate the relationship between tear geometry and muscle fatty degeneration in shoulders with a deficient rotator cuff. METHODS Ultrasonograms of both shoulders of 262 patients were reviewed to asses...

BACKGROUND The purpose of this study was to determine when cuff re-tear commonly occurs in the postoperative period and to investigate the clinical factors that might predispose to an early cuff re-tear. METHODS All patients with rotator cuff (supraspinatus ± infraspinatus) tear that required arthroscopic repair during the period between June 1, 2010, and May 31, 2012, with completed serial u...

BACKGROUND AND PURPOSE We describe the structural abnormalities in the painful shoulder of stroke survivors and their relationships to clinical characteristics. Method- Eighty-nine chronic stroke survivors with poststroke shoulder pain underwent T1- and T2-weighted multiplanar, multisequence MRI of the painful paretic shoulder. All scans were reviewed by one radiologist for the following abnorm...

INTRODUCTION: There are various shapes of full-thickness rotator cuff tears, but they are mainly categorized into two types; crescent-shaped and L-shaped tears. Although it is widely accepted that the tear often propagates with time, the exact propagation pattern in each type of tear is still remains unknown. In the present study, we attempted to clarify the stress distribution in the tendons w...

BACKGROUND Long head biceps (LHB) degeneration, in combination with rotator cuff tears, can be a source of chronic shoulder pain. LHB tenotomy reduces pain and improves joint function although the pathophysiological context is not well understood. Tendon integrity depends on the extracellular matrix (ECM), which is regulated by matrix metalloproteinases (MMP). It is unclear which of these enzym...

BACKGROUND Little is known about the influence of rotator cuff pathology on sleep. The purpose of this study was to determine which patient-reported factors correlate with sleep disturbance in patients with rotator cuff disease. METHODS A nonrandomized, cross-sectional cohort study was performed to evaluate the effects of rotator cuff disease on sleep quality. Data collected at time zero (bef...

Large to massive rotator cuff tears are challenging to repair, although there are several options for dealing with them. Among them, superior capsular reconstruction was recently introduced as an effective procedure for retaining the static stability of the shoulder joint and preventing the progression to cuff tear arthropathy. The purpose of this technique-based article is to describe a surgic...

BACKGROUND The purpose of this prospective study was to report the long-term risks of rotator cuff tear enlargement and symptom progression associated with degenerative asymptomatic tears. METHODS Subjects with an asymptomatic rotator cuff tear in one shoulder and pain due to rotator cuff disease in the contralateral shoulder enrolled as part of a prospective longitudinal study. Two hundred a...
