PURPOSE: To investigate the 2-year postoperative clinical and subjective outcomes after arthroscopic rotator cuff repair (ARCR) with xenologous porcine dermal patch augmentation compared with ARCR alone. METHODS: Patients aged 60 years or older with a complete supraspinatus (SSP) tendon tear underwent primary ARCR with a transosseous-equivalent technique. By use of a matched-pair comparative trial design, a consecutive series of 20 patients receiving additional xenologous porcine dermal patch augmentation (patch group) was matched by tear location with 20 patients who received ARCR only (control group)...

BACKGROUND: The repair of anterior L-shaped tears is usually difficult because of the lack of anterior rotator cuff tendon to cover the footprint. The biceps tendon is usually exposed from the retracted anterolateral corner of the torn tendon and can be easily used to augment rotator cuff repair. Hypothesis/Purpose: This study compared the clinical outcomes of the biceps augmentation technique with those of partial tendon repair for the arthroscopic treatment of large anterior L-shaped rotator cuff tears to evaluate the role of additional biceps augmentation in tendon healing...

Various biomaterial technologies are promising for tissue engineering, including electrospinning, but commercial scale-up of throughput is difficult. The goal of the study was to evaluate meltblown fabrics as candidate scaffolds for rotator cuff tendon tissue engineering. Meltblown poly(lactic acid) fabrics were produced with several polymer crystallinities and airflow velocities (500(low), 900(medium) or 1400(high) m<sup>3</sup>air/hour/m fabric). Fiber diameter, alignment, and baseline bi-directional tensile mechanical properties were evaluated...

Healing of rotator cuff (RC) injuries with current suture or augmented scaffold techniques fails to regenerate the enthesis and instead forms a weaker fibrovascular scar that is prone to subsequent failure. Regeneration of the enthesis is the key to improving clinical outcomes for RC injuries. We hypothesized that the utilization of our tissue-engineered tendon to repair either an acute or a chronic full-thickness supraspinatus tear would regenerate a functional enthesis and return the biomechanics of the tendon back to that found in native tissue...

Despite the vast improvement in techniques for arthroscopic rotator cuff surgery, repairs of massive and large tears remain an issue as they are associated with significantly high failure rates, particularly in the elderly population. As a result, there has been a focus of attention to improve rotator cuff repair healing rates. One of the strategies is augmentation of the repair with a patch. Arthroscopic augmentation is, however, technically demanding with challenges in introduction and stabilization of the patch...

BACKGROUND: There are several options for reconstruction of proximal humerus resections after wide resection for malignant tumors in children. The clavicula pro humero technique is a biologic option that has been used in the past, but there are only scant case reports and small series that comment on the results of the procedure. Because the longevity of children mandates a reconstruction with potential longevity not likely to be achieved by other techniques, the clavicula pro humero technique may be a potential option in selected patients...

Biceps tendinopathy is a relatively common ailment that typically presents as pain, tenderness, and weakness in the tendon of the long head of the biceps brachii. Though it is often associated with degenerative processes of the rotator cuff and the joint, this is not always the case, thus, the etiology remains considerably unknown. There has been recent interest in elucidating the pathogenesis of tendinopathy, since it can be an agent of chronic pain, and is difficult to manage. The purpose of this article is to critically evaluate relevant published research that reflects the current understanding of pain and how it relates to biceps tendinopathy...

Tearing of the rotator cuff commonly occurs as among one of the most frequently experienced tendon disorders. While treatment typically involves surgical repair, failure rates to achieve or sustain healing range from 20 to 90%. The insufficient capacity to recover damaged tendon to heal to the bone, especially at the enthesis, is primarily responsible for the failure rates reported. Various types of biomaterials with special structures have been developed to improve tendon-bone healing and tendon regeneration, and have received considerable attention for replacement, reconstruction, or reinforcement of tendon defects...

Symptomatic partial-thickness rotator cuff tears and full-thickness tears with poor tissue quality often pose a dilemma for orthopaedic surgeons. Despite advances in repair techniques and fixation devices, retear rates remain high. Progression of partial-thickness tears has been noted to be over 50%, with remaining fibers seeing increased strain. Patch augmentation that induces a healing response while decreasing peak strain of adjacent tissue is becoming more popular among orthopaedic surgeons. Therefore, we present an all-arthroscopic technique guide for application of a Food and Drug Administration-approved bovine bioinductive patch (Rotation Medical, Plymouth, MN)...

The management of irreparable rotator cuff tears is a difficult problem to deal with. The options include nonoperative route with anterior deltoid exercises, debridement with or without long head of biceps tenotomy, partial rotator cuff repair, tuberoplasty, muscle transfer, patch augmentation, biodegradable spacers, and reverse shoulder arthroplasty. None of these options are without their limitations. In recent years, arthroscopic superior capsular reconstruction has gained popularity as an alternative technique to address irreparable rotator cuff tears...

BACKGROUND: Fatty infiltration in skeletal muscle is directly linked to loss of muscle strength and is associated with various adverse physical outcomes such as muscle atrophy, inflammation, insulin resistance, mobility impairments, and even mortality in the elderly. Aging, mechanical unloading, muscle injury, and hormonal imbalance are main causes of muscle fat accumulation, and the fat cells are derived from muscle stem cells via adipogenic differentiation. However, the pathogenesis and molecular mechanisms of fatty infiltration in muscles are still not fully defined...

Rotator cuff (RC) tears represent a large proportion of musculoskeletal injuries attended to at the clinic and thereby make RC repair surgeries one of the most widely performed musculoskeletal procedures. Despite the high incidence rate of RC tears, operative treatments have provided minimal functional gains and suffer from high re-tear rates. The hypocellular nature of tendon tissue poses a limited capacity for regeneration. In recent years, great strides have been made in the area of tendonogenesis and differentiation towards tendon cells due to a greater understanding of the tendon stem cell niche, development of advanced materials, improved scaffold fabrication techniques, and delineation of the phenotype development process...

BACKGROUND: Recurrence rate of rotator cuff tears is still high despite the improvements of surgical techniques, materials used and a better knowledge of the healing process of the rotator cuff tendons. Large to massive rotator cuff tears are particularly associated with a high failure rate, especially in elderly. Augmentation of rotator cuff repairs with extracellular matrix or synthetic patches has gained popularity in recent years with the aim of reducing failure. The aim of this study was to investigate the outcome of rotator cuff repairs augmented with denatured extracellular matrix in a series of patients who underwent arthroscopic rotator cuff repair for large to massive tears...

Chronic tendinopathy in an active and ageing population represents an increasing burden to healthcare systems. Rotator cuff tendinopathy alone accounts for approximately 70 % of all shoulder pain. Tendinopathic tissue has a disorganised extracellular matrix, altered vasculature, and infiltration of fibroblasts and inflammatory cells. This altered biology may contribute to the limited success of surgical repair strategies. Electrospun resorbable scaffolds can potentially enhance endogenous repair mechanisms by influencing the tissue microenvironment...

INTRODUCTION: Rotator cuff tears are common diseases of the upper extremity. There are no recommendations to the surgeon on how to prepare the footprint to ensure optimal tendon-to-bone healing. However, biologic augmentation using stem cells and growth factors is considered to encourage the healing process of the tendon. The aim of the study was to investigate the biomechanical and histological outcome of different footprint preparations in rotator cuff repair. MATERIAL AND METHODS: One hundred and eighty-nine Sprague-Dawley rats were randomly assigned to either spongialization, radiofrequency ablation or an untreated control group...
