Latissimus dorsi tendon transfer is an effective option for young and active patients with massive irreparable posterosuperior rotator cuff tears and intact subscapularis tendon. This approach has been shown to relieve pain and improve shoulder function in both the short and long term. We describe a surgical technique using an acromial osteotomy to better expose the greater tuberosity for the tendon transfer without disrupting the deltoid muscle. The latissimus dorsi tendon is reinforced with a human dermal collagen matrix (GraftJacket; Wright Medical Group) for additional augmentation of the muscle to gain more excursion for the tendon transfer to the greater tuberosity...

A revision rotator cuff repair is a technically challenging surgical procedure. This can be further complicated by the presence of poor quality of the cuff tissue, as well as a large greater tuberosity cyst, typically located at the rotator cuff footprint. This Technical Note discusses the surgical approach to deal with a revision rotator cuff tear with a large humeral head cyst. This described arthroscopic technique is performed in a single-stage procedure using a human dermal allograft (GraftJacket) for augmentation...

BACKGROUND: Retearing after rotator cuff surgery is a major clinical problem. Numerous scaffolds are being used to try to reduce retear rates. However, few have demonstrated clinical efficacy. We hypothesize that this lack of efficacy is due to insufficient mechanical properties. Therefore, we compared the macro and nano/micro mechanical properties of 7 commercially available scaffolds to those of the human supraspinatus tendons, whose function they seek to restore. METHODS: The clinically approved scaffolds tested were X-Repair, LARS ligament, Poly-Tape, BioFiber, GraftJacket, Permacol, and Conexa...

Massive irreparable rotator cuff tears can be reconstructed with latissimus dorsi tendon transfers (LDTT). Although uncommon, the natural length of the latissimus dorsi tendon (LDT) could be insufficient for transfer even after adequate soft tissue releases. Descriptions of cases where grafts were needed to lengthen the LDT are therefore rare. We located only two reports of the use of an acellular dermal matrix to increase effective tendon length in tendon transfers about the shoulder: (1) GraftJacket patch for a pectoralis major tendon reconstruction and (2) ArthroFlex® patch for LDTT...

Tibialis anterior tendon rupture causes substantial morbidity. The present study describes the outcomes of augmented, half-thickness tibialis anterior tendon segment transposition, a novel reconstruction technique. This was an institutional review board-approved retrospective review of 3 patients with surgically treated attritional distal rupture with 1-year follow-up. The postdebridement tendon defect prohibited primary repair and was managed by distal transposition of a half-thickness healthy segment. This repair was augmented with human acellular dermal matrix allograft (Graftjacket, Wright Medical Technology, Memphis, TN)...

Surgical repairs of rotator cuff tears have high re-tear rates and many scaffolds have been developed to augment the repair. Understanding the interaction between patients' cells and scaffolds is important for improving scaffold performance and tendon healing. In this in vitro study, we investigated the response of patient-derived tenocytes to eight different scaffolds. Tested scaffolds included X-Repair, Poly-Tape, LARS Ligament, BioFiber (synthetic scaffolds), BioFiber-CM (biosynthetic scaffold), GraftJacket, Permacol, and Conexa (biological scaffolds)...

BACKGROUND: Treatment of glenohumeral osteoarthritis in young patients is challenging. Total shoulder arthroplasty reliably addresses pain and dysfunction but compromises glenoid bone stock. Various efforts have been made to avoid a prosthetic glenoid component or to prevent glenoid erosion after hemiarthroplasty. Capsular interposition, meniscal allograft, and more recently, GraftJacket (Wright Medical Technology Inc, Arlington, TN, USA), a human dermal collagen allograft, have been proposed for interposition arthroplasty in young patients with glenohumeral osteoarthritis...

BACKGROUND: We describe a retrospective study that uses the Broström-type surgical procedure with modifications that augment deficient and torn ligaments with acellular human dermal grafts. At the onset of this study, the most prevalent dermal graft available to us was GraftJacket (Wright Medical Technology, Arlington, Tennessee). Greater than 50% of the study participants were grafted with this product, but more recently other equally effective human dermal grafts have been used with no apparent difference...

OBJECTIVE: Rising prevalence of obesity and uncontrolled diabetes mellitus has resulted in an increasing number of patients with multiple comorbidities who require treatment for chronic complex wounds. Because patients with diabetes and foot ulcers may have a higher risk for amputations, techniques that facilitate complex wound healing and prevent limb amputation are desirable. Here, we investigate a limb preservation strategy that includes application of a human acellular dermal wound matrix (HADWM)...

UNLABELLED: Diabetic foot ulcers (DFUs) affect a significant number of people and the treatment is challenging and costly. Since only a small portion of patients respond to standard care, the majority require more advanced wound healing interventions. Human acellular dermal matrices-regenerative tissue matrices derived from human tissue and processed from screened donated skin-can aid wound closure by restoring the missing physiological factors to the microenvironment. A literature review of the clinical literature was performed to estimate the comparative effectiveness of one specific human acellular dermal wound matrix (HADWM; Graftjacket regenerative tissue matrix) versus standard care in healing DFUs...

A chronic wound fails to complete an orderly and timely reparative process and places patients at increased risk for wound complications that negatively impact quality of life and require greater health care expenditure. The role of extracellular matrix (ECM) is critical in normal and chronic wound repair. Not only is ECM the largest component of the dermal skin layer, but also ECM proteins provide structure and cell signalling that are necessary for successful tissue repair. Chronic wounds are characterised by their inflammatory and proteolytic environment, which degrades the ECM...

BACKGROUND: Biologic glenoid resurfacing is a treatment option for young patients with glenohumeral arthritis. An optimal synthetic graft for glenoid resurfacing should allow repopulation with host cells, be durable enough to tolerate suture fixation and forces across the joint, and present no host inflammatory response. We report two cases of giant cell reaction to GraftJacket(®) after biologic glenoid resurfacing. CASE DESCRIPTION: Two patients who underwent hemiarthroplasty and biologic glenoid resurfacing using GraftJacket(®) had a foreign body giant cell reaction that required revision surgery...

Management of failed first metatarsophalangeal joint implant arthroplasty, especially in the face of infection, is an area of debate without a clear consensus. The purpose of the present report was to explore a new option of reconstructing the joint with an acellular dermal matrix substance in a single case study during a 12-month follow-up period. A staged approach that began with removal of the failed 2-component great toe implant, Koenig(®), excisional debridement of the wound with resection of the necrotic bone (proximal phalanx and distal portion of the first metatarsal bones), and culture-specific antibiosis therapy...

BACKGROUND: Acellular human dermal matrix grafts (Graftjacket; Wright Medical Technology, Arlington, TN, USA) are used clinically for rotator cuff augmentation without a detailed understanding of their biomechanical effects. The purpose of this study was to evaluate the effect of augmentation with dermal grafts on the biomechanical effects of rotator cuff repairs. METHODS: Nine matched pairs of human cadaveric shoulders were used. A single-row rotator cuff repair combined with an augmentation graft was performed on one shoulder, and a single-row repair was performed on the contralateral shoulder as a control...

The diabetic foot remains a major cause of morbidity worldwide. Even though considerable progress has been achieved over the past years, there is still an urgent need for improvement. While established therapeutic modalities (revascularization, casting and debridement) remain the mainstay of management, there is, therefore, continuous development of new treatment options. This review provides an outlook of advances in topical treatment, including bioengineered skin substitutes (such as Dermagraft, Apligraf, HYAFF, OASIS and Graftjacket), extracellular matrix proteins (such as Hyalofill and E-matrix), as well as miscellaneous further therapeutic adjuncts...

Current biomedical scaffolds utilized in surgery to repair soft tissues commonly fail to meet the optimal combination of biomechanical and tissue regenerative properties. Carbon is a scaffold alternative that potentially optimizes the balance between mechanical strength, durability, and function as a cell and biologics delivery vehicle that is necessary to restore tissue function while promoting tissue repair. The goals of this study were to investigate the feasibility of fabricating hybrid fibrous carbon scaffolds modified with biopolymer, polycaprolactone and to analyze their mechanical properties and ability to support cell growth and proliferation...
