Shoulder instability and rotator cuff pathology can provide a challenging problem, especially in the revision setting. Allograft use in primary or revision surgical intervention for shoulder instability and rotator cuff tear may be a valuable resource. This paper reviews allograft tissue use in shoulder surgery for instability and rotator cuff tear.

REVIEW
Raymond E Chen, Ilya Voloshin
The long head of the biceps brachii is a well-known "pain generator" in the shoulder. Biceps tendinitis, instability, and rupture encompass the majority of symptomatic lesions. Clinical diagnosis, particularly of biceps tendinitis, can be difficult, given the nonspecific physical examination findings. Treatment options are initially nonoperative, with surgical management reserved for specific presentations or refractory cases. In recent years, biceps tenodesis and tenotomy have become the mainstays of operative treatment...

Failed rotator cuff repairs can pose a clinical challenge to the treating orthopedic surgeon. There are many nonsurgical and surgical options available to address the failed rotator cuff repair. Surgical options include revising the primary repair, partial or nonanatomic repair, tendon transfer, biological augmentation or use of tissue-engineered grafts for reconstruction, or total joint arthroplasty (typically with a modern reverse total shoulder arthroplasty system). The treating surgeon must assess the patient's functional status, health status, and expectations in order to customize the appropriate treatment plan for addressing the failed rotator cuff repair...

REVIEW
Alexis Dang, Michael Davies
Rotator cuff disease encompasses a broad spectrum of injury and pathology with an increasing incidence with age. Pain with overhead activity, localizing to the deltoid region, and loss of active range of motion of the shoulder are among the most common presenting symptoms. Treatment options are dependent on the extent of disease and patient symptoms, and may range from physical therapy to surgical repair using a variety of possible techniques. Tear thickness, size, and morphology frequently dictate the repair techniques that are used, such as margin convergence, anterior and posterior interval slides, and mobilization of the rotator interval and supraspinatus with a subscapularis repair...

REVIEW
Meagan M McCarthy, Eric McCarty
Articular cartilage injuries in the glenohumeral joint present a unique and difficult problem for the patient and surgeon alike. Various etiologies exist for the development of these cartilage lesions; therefore, treatment options are vast and must be chosen thoughtfully, especially in the young, active patient. Across all treatment modalities, the goal is for the patient to regain lasting function and mobility while decreasing pain.

REVIEW
Matthew J Best, Miho J Tanaka
Multidirectional instability (MDI) is a debilitating condition that involves chronic subluxation or dislocation of the shoulder in >1 direction. Numerous proposed mechanisms of MDI exist, which occurs in the setting of redundant capsular tissue. Symptoms can range from recurrent dislocations or subluxations to vague aching pain that disrupts activities of daily living. Magnetic resonance imaging is often performed during evaluation of this condition, although magnetic resonance arthrography may provide more detailed images of the patulous capsule...

REVIEW
Edward Lyle Cain, Michael K Ryan
Recurrent traumatic glenohumeral instability is a complex problem with multiple variables to consider, but patient demographics, activities, as well as clinical and radiographic findings provide significant information to help choose the best treatment option. Although nonoperative treatment is a viable option for primary glenohumeral instability and in-season instability, recurrent instability exhibits anatomic factors which render nonsurgical treatment limited in scope. A proper patient history, clinical examination, and standard and advanced imaging are necessary in the assessment of patients with recurrent traumatic instability...

REVIEW
Jeffrey R Dugas, Matthew W Crozier
Because of the lack of bony restraints and minimal articular contact, the glenohumeral joint can attain significant range of motion; however, this results in the propensity for instability. The most generic form of instability, traumatic anterior instability, reliably produces a series of pathoanatomic findings. While reliable, these findings contribute to the complexities of caring for patients after an initial instability event. Numerous studies have examined this issue and determined that careful consideration of patient factors can guide successful treatment, whether it be surgical or nonsurgical, after initial instability...

The shoulder is a complex joint, with a wide range of motion and functional demands. An understanding of the intricate network of bony, ligamentous, muscular, and neurovascular anatomy is required in order to properly identify and diagnose shoulder pathology. There exist many articulations, unique structural features, and anatomic relationships that play a role in shoulder function, and therefore, dysfunction and injury. Evaluation of a patient with shoulder complaints is largely reliant upon physical exam...

REVIEW
Neil Bakshi, Michael T Freehill
The overhead athlete places tremendous forces across the shoulder which result in necessary adaptive, but also potentially pathologic structural change. In this chapter we aim to review the biomechanics of throwing, the mechanisms of injury with overhead sports, the detailed history, and physical examination in this population, and concluding with specific diagnoses and the various treatment options.

It is commonly recommended to reconstruct a torn anterior cruciate ligament in active patients; however, there is no consensus concerning the tissue source to use for the reconstruction. Bone-patellar tendon-bone and hamstring (semitendinosis +/- gracilis) autografts are most commonly used, with allografts being another option. Each tissue has its pros and cons, with allografts often cited as having higher failure rates. However, review of the literature comparing autografts and allografts have showed similar outcomes in age-matched adult populations...

This is a study of amniotic epithelial cells, which form the innermost layer of the amniotic membrane. These cells can be easily isolated and display peculiar and unique properties, such as plasticity and differentiation potential toward the 3 germinal layers, that may aid regeneration and/or repair of damaged or diseased tissues and organs. A robust literature based on in vitro, experimental, and clinical studies in large animals demonstrates that these cells can enhance the regeneration of tendons, bone, and articular cartilage...

Tissue engineering strategies have relied on engineered 3-dimensional (3D) scaffolds to provide architectural templates that can mimic the native cell environment. Among the several technologies proposed for the fabrication of 3D scaffold, that can be attractive for stem cell cultivation and differentiation, moulding or bioplotting of hydrogels allow the stratification of layers loaded with cells and with specific additives to obtain a predefined microstructural organization. Particularly with bioplotting technology, living cells, named bio-ink, and additives, such as biopolymer microdevices/nanodevices for the controlled delivery of growth factors or biosignals, can be organized spatially into a predesigned 3D pattern by automated fabrication with computer-aided digital files...

Tendon injuries, bone defects, and cartilage defects are complex clinical conditions leading to pain and dysfunctions. Tendon, bone, and cartilage are highly specialized and organized tissues, and the self-healing may be limited by their histologic features, or impaired by the local conditions. Furthermore, the resultant tissue often shows inferior properties compared with native tissue, leading to high rates of reruptures and revision surgeries. A growing field of research has explored tendon, bone, and cartilage regeneration using mesenchymal stem cells (MSCs), because of their multipotency, and because they are relatively easy to harvest...

Joint conditions incapacitate free movement driving to a sedentary lifestyle, a major risk factor for chronic diseases. Regenerative procedures, involving the use of mesenchymal stem/stromal cells along with platelet-rich plasma (PRP), can help patients with these conditions. We describe the main characteristics of cellular products (bone marrow concentrate, stromal vascular fraction of adipose tissue, and mesenchymal stem/stromal cells derived from these tissues), and the potential benefits of combination with PRP in 3 scenarios: PRP lysates used during laboratory cell expansion; PRP to prime cellular products or the host tissue before cell implantation; PRP used as a vehicle for cell transplantation and to provide trophic signals...

In the last few decades, several techniques have been used to optimize tendon, ligament, and musculoskeletal healing. The evidence in favor of these techniques is still not proven, and level I studies are lacking. We performed an analysis of the therapeutic strategies and tissue engineering projects recently published in this field. Here, we try to give an insight into the current status of cell therapies and the latest techniques of bioengineering applied to the field of orthopedic surgery. The future areas for research in the management of musculoskeletal injuries are outlined...

Arthroscopic rotator cuff repair is a commonly performed repair. Technical developments provide surgeons the tools to create biomechanically robust repairs. How can the biological response mirror the strong and stable surgery? Platelet-rich plasma (PRP) is a supraphysiological platelet concentration which may positively augment rotator cuff healing. Not all PRPs are the same. High leukocyte levels and thrombin activation may be detrimental to tendon healing. Thrombin activation triggers an immediate release of growth factors and may actually inhibit some parts of the healing response...
