OBJECTIVE: The aim of this article is to review the postoperative MRI appearances of irreparable massive rotator cuff tears (RCTs) after surgery was performed using newer techniques, including patch repair, muscle tendon transfer, superior capsular reconstruction, and subacromial balloon implantation. CONCLUSION: Newer surgical techniques are emerging for the management of massive RCTs. As radiologists become increasingly likely to encounter postoperative imaging studies of RCTs repaired using these techniques, familiarity with the normal postoperative appearances and complications associated with these techniques becomes important...

Despite relatively good results of current symptomatic treatments for rotator cuff disease, there has been an unmet need for fundamental treatments to halt or reverse the progress of disease. The purpose of this study was to assess the safety and efficacy of intratendinous injection of autologous adipose-tissue derived MSCs (AD MSCs) in patients with rotator cuff disease. The first part of the study consists of 3 dose-escalation cohorts; the low- (1.0x107 cells), mid- (5.0x107 ), and high-dose (1.0x108 ) groups with 3 patients each for the evaluation of the safety and tolerability...

PURPOSE: To determine the influence of preoperative factors on reparability of rotator cuff tears (RCTs) and yield a predictive model for predicting irreparability preoperatively. METHODS: Among patients with full-thickness RCTs, the reparable group underwent arthroscopic rotator cuff repairs for reparable RCTs whereas the irreparable group underwent alternative surgical procedures for irreparable RCTs. We analyzed age, sex, chronic pseudoparalysis (CPP), mediolateral and anteroposterior tear sizes, acromiohumeral distance (AHD), tangent sign, fatty infiltration (FI) (group 1, Goutallier stage 0 or 1; and group 2, Goutallier stage 2, 3, or 4), and tendon involvement (TI) (type 1, supraspinatus; type 2, supraspinatus and subscapularis; type 3, supraspinatus and infraspinatus; and type 4, all 3 tendons)...

PURPOSE: The purpose of this study was to explore whether preservation of native enthesis during rotator cuff repair (RCR) results in a histologically and biomechanically better rotator cuff-greater tuberosity (RC-GT) connection in an animal model. METHODS: Thirty-six New Zealand white rabbits were used in this study. The supraspinatus tendons were cut from the footprint to create a rotator cuff tear (RCT) on both shoulders, followed by immediate repair, with a 1 mm thick tendon stump remaining on the footprint...

It is still unknown whether glenoid inclination or lateral acromial roof extension is a more important determinant for development of rotator cuff tears (RCT) or osteoarthritis (OA) of the shoulder. It was the purpose of this study, to evaluate whether there is a potential predominance of one of these factors in pathogenesis of RCT or concentric OA. We analyzed 70 shoulders with advanced degenerative RCT and 54 shoulders with concentric OA undergoing primary shoulder arthroplasty (anatomical or reverse) using antero-posterior radiography and multiplanar computed tomography...

Surgical repair of rotator cuff tears presents a significant clinical challenge with high failure rates and inferior functional outcomes. Graft augmentation improves repair outcomes, however currently available grafting materials have limitations. While cell-seeded decellularized tendon slices may facilitate cell infiltration, promote tendon incorporation and preserve original mechanical strength, the unique fibrocartilage zone is yet to be successfully reestablished. In this study, we investigated the biological and mechanical properties of an engineered tendon-fibrocartilage-bone composite (TFBC) with cyclic tension (3% strain, 0...

Superior capsular reconstruction has received increased attention as a surgical technique to address massive 'irreparable' rotator cuff tears; however, the functional limitations and surgical techniques associated with this repair have yet to be sufficiently explored. The goal of this study was to utilize a multidisciplinary approach to characterize the biomechanics of this repair by: 1) identifying activities of daily living that may overburden graft, and 2) optimizing surgical techniques used during implantation...

BACKGROUND: Most of the literature on shoulder arthroplasty failure comes from high-volume centers. These reports tend to exclude the experience of community orthopedic surgeons, who perform most of the shoulder joint replacements. METHODS: We analyzed the failure reports mandated by the US Food and Drug Administration for all hospitals. Each reported event from 2012 to 2016 was characterized by implant, failure mode, and year of surgery. RESULTS: For the 1673 anatomic arthroplasties, the most common failure modes were glenoid component failure (20...
