Arthroscopic Extreme Medialized Repair for Massive Rotator Cuff Tear: Resection of Cartilage and Subchondral Bone Over the Top of the Humeral Head.

Rotator cuff repair is a widely performed surgery. Its purpose is to improve shoulder function, fix tendons to bones, restore anatomical structure, and prevent the progression of rotator cuff tear arthropathy and associated muscle degeneration. However, in large and massive tears, the tension imposed during repair becomes too high.

Alteration of coracoacromial ligament thickness at the acromial undersurface in patients with rotator cuff tears.

Background: Some researchers have stated that magnetic resonance imaging (MRI) is useful for assessing the coracoacromial ligament (CAL) at the acromial undersurface. However, few studies have investigated the reliability and clinical significance of MRI findings for the CAL at the acromial undersurface. The purpose of this study was to determine the association between CAL thickness at the acromial undersurface and rotator cuff tear size.

Where and what damage occurs at the acromial undersurface in patients with rotator cuff tears?

Background: The gross pathology of the acromial undersurface in shoulders with rotator cuff tears with subacromial impingement is not completely understood. Many researchers have focused on damage to the anterior one-third area of the acromial undersurface, but few have studied the middle and posterior one-third areas. The purpose of this study was to clarify where and what damage occurs at the acromial undersurface in patients with rotator cuff tears.

Newly devised anterior portal technique for arthroscopic bankart repair using suture anchors.

Many techniques and instrument systems have been developed for performing arthroscopic Bankart repair using a suture anchor. The suture anchor procedure relies on a secure knot, which does not become entangled in the anterior portal. A newly devised anterior portal technique can solve this problem.
