BACKGROUND: Intra-synovial tendon injuries display poor healing, which often results in reduced functionality and pain. A lack of effective therapeutic options has led to experimental approaches to augment natural tendon repair with autologous mesenchymal stem cells (MSCs) although the effects of the intra-synovial environment on the distribution, engraftment and functionality of implanted MSCs is not known. This study utilised a novel sheep model which, although in an anatomically different location, more accurately mimics the mechanical and synovial environment of the human rotator cuff, to determine the effects of intra-synovial implantation of MSCs...

A 'terrible triad' of anterior shoulder dislocation, axillary nerve damage and rotator cuff tear has been previously described. However, we are unaware of any report of anterior shoulder dislocation, humeral fracture, axillary neuropathy and subsequent rotator cuff tear requiring surgery when the axillary neuropathy was deemed permanent. We report the case of a 20-year-old woman who fell in a motocross accident and had an anterior shoulder dislocation, humeral fracture and axillary neuropathy. The fracture was treated surgically with open reduction and internal fixation...

BACKGROUND: Advances in DNA sequencing technologies have made it possible to detect microbial genome sequences (microbiomes) within tissues once thought to be sterile. We used this approach to gain insights into the likely sources of Cutibacterium acnes (formerly Propionibacterium acnes) infections within the shoulder. METHODS: Tissue samples were collected from the skin, subcutaneous fat, anterior supraspinatus tendon, middle glenohumeral ligament, and humeral head cartilage of 23 patients (14 male and 9 female patients) during primary arthroplasty surgery...

Background: After rotator cuff repair, some patients have ongoing problems significant enough to warrant presentation to a clinic for reassessment. Purpose/Hypothesis: The purpose of this study was to determine whether this cohort of patients was more likely to have a healed rotator cuff. We hypothesized that patients who had an unscheduled postoperative visit were more likely to have a healed rotator cuff than those who did not have an unscheduled postoperative visit...

Despite the development in shoulder surgery, massive irreparable rotator cuff tears still remain challenging for orthopaedic surgeons. Many surgical methods are addressed to this kind of pathology, but each of them has its own limitations. We decided to fuse the ideas of superior capsular reconstruction, "GraftJacket" technique, and partial rotator cuff repair. In this way, the technique using the long head biceps tendon simultaneously as a vascularized bridge between rotator cuff remnants and greater tubercle and as a depressor for the humeral head was created...

INTRODUCTION: There is currently no consensus on the choice between tenotomy and tenodesis of the long head of the biceps tendon in rotator cuff repair. The Popeye sign is often seen as a drawback of tenotomy. The main objective of the present study was to determine the frequency and clinical impact of the Popeye sign. HYPOTHESIS: The Popeye sign is rarely found clinically, and shows little functional impact following tenotomy. MATERIALS AND METHODS: A single-center non-randomized prospective study was conducted between February and October 2015 in all patients undergoing rotator cuff surgery...

BACKGROUND: This study investigated the feasibility and safety of all-suture anchors in arthroscopic rotator cuff repair. METHODS: All patients were diagnosed with a rotator cuff tear by ultrasound or magnetic resonance imaging (MRI). Patients with partial tears, massive tears, subscapularis tears, or previous shoulder surgery, were excluded. MRI and clinical outcome were investigated in all patients at 1.58 years (range, 1.0-2.0 years) after rotator cuff repair with all-suture anchors (prospective case series)...

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...

BACKGROUND: The impending burden of revision shoulder arthroplasty has increased interest in outcomes of revision procedures. Painful glenoid arthrosis following hemiarthroplasty is a common cause of reoperation, and conversion to anatomic total shoulder arthroplasty is one option. METHODS: We identified patients who underwent revision of painful hemiarthroplasty to total shoulder arthroplasty over a 15-year period in a single tertiary-care health system. Presurgical and operative data were analyzed for 28 patients who met the inclusion and exclusion criteria...
