BACKGROUND: Tendons are dense connective tissues and critical components for the integrity and function of the musculoskeletal system. Tendons connect bone to muscle and transmit forces on which locomotion entirely depends. Due to trauma, overuse and age-related degeneration, many people suffer from acute or chronic tendon injuries. Owing to their hypovascularity and hypocellularity, tendinopathies remain a substantial challenge for both clinicians and researchers. Surgical treatment includes suture or transplantation of autograft, allograft or xenograft, and these serve as the most common technique for rescuing tendon injuries...

BACKGROUND: In a recently published, prospective randomized controlled trial (RCT) comparing aseptically processed dehydrated human amnion/chorion allograft (dHACA) to standard of care (SOC), 85% wound closure rates were reported in the dHACA arm while only 25% of patients in the SOC arm healed. OBJECTIVE: The purpose of this retrospective crossover study is to evaluate the effectiveness of dHACA in those patients that failed to respond to the SOC treatments and who exited the original study after failing up to 12 weeks of SOC treatment...

Common terminal sterilization methods are known to alter the natural structure and properties of soft tissues. One approach to providing safe grafts with preserved biological properties is the combination of a validated chemical sterilization process followed by an aseptic packaging process. This combination of processes is an accepted method for production of sterile healthcare products as described in ANSI/AAMI ST67:2011. This article describes the validation of the peracetic acid and ethanol-based (PAAE) chemical sterilization process for allograft dermal tissues at the Musculoskeletal Transplant Foundation (MTF, Edison, NJ)...

BACKGROUND: Allogeneic grafts derived from amnion/chorion are known to be efficacious in healing chronic diabetic foot ulcerations (DFUs). The goal of this study was to compare aseptically processed dehydrated human amnion and chorion allograft (dHACA) versus standard of care (SOC) in facilitating wound closure in nonhealing DFUs. METHODS: Patients with DFUs treated with SOC (off-loading, appropriate debridement, and moist wound care) after a 2-week screening period were randomized to either SOC or wound-size-specific dHACA (AmnioBand, Musculoskeletal Transplant Foundation, Edison, N...

BACKGROUND: Acellular dermal matrices (ADMs) are frequently used in reconstructive surgery and as scaffolds to treat chronic wounds. The 3-dimensional architecture and extracellular matrix provide structural and signaling cues for repair and remodeling. However, most ADMs are not uniformly porous, which can lead to heterogeneous host engraftment. In this study, we hypothesized that a novel human reticular ADM (HR-ADM; AlloPatch Pliable, Musculoskeletal Transplant Foundation, Edison, N...

PURPOSE: The objective of this study was to evaluate the performance of acellular human dermis reinforcement during laparoscopic hiatal hernia repair. METHODS: A prospective non-randomized, single institution study enrolled patients undergoing laparoscopic hiatal hernia repair. Acellular human dermis, FlexHD (Musculoskeletal Transplant Foundation, Edison, NJ) or AlloDerm (LifeCell Inc., Branchburg, NJ) were used to buttress the repair after primary closure. A protocol barium swallow (BAS) was performed at 6 months and then as needed due to clinical indications...

BACKGROUND: Damage control surgery and management of the open abdomen has led to a significant improvement in survival in trauma and emergency surgical patients. However, subsequent abdominal reconstruction has become a significant challenge. The objective of this study was to compare 2 different acellular dermal matrices in regard to hernia recurrence and complications in patients who present with a large complicated ventral hernia as a result of trauma or emergency surgery. STUDY DESIGN: A prospective quasi-experimental time-interrupted series design was used to evaluate the incidence of hernia recurrence in trauma/emergency surgery patients who had a ventral hernia repair with a biologic matrix...

IMPORTANCE: Acellular dermal matrices have many current and potential applications, but their long-term safety has not been extensively studied. In particular, limited information exists regarding such materials' resistance to infection. OBJECTIVE: To assess the resistance to microbial penetration of common acellular dermal matrix materials used in reconstruction after skin cancer excision, treatment of chronic ulcers and burns, breast reconstruction, hernia repairs, and other applications...

Defining the ideal material for frontal sinus obliteration remains controversial. Autogenous cancellous bone is effective because of its biological properties: it undergoes fast revascularization acting as an active scaffold for bone healing, but is linked to additional donor site morbidity. Bone dust harvesting from the skull surface produces no sequelae but availability is limited. Many efforts have been made to overcome these drawbacks, and an ideal bone substitute sought. Demineralized Bone Matrix (DBX; Musculoskeletal Transplant Foundation, Edison, NJ, USA) is a commercially available product composed of demineralized bone particles reduced after proper processing of human bone in combination with sodium hyaluronate...

BACKGROUND: There are many products approved for aesthetic soft tissue augmentation. Despite this abundance, there is limited objective data regarding safety, longevity, and complication rates. Instead, most reports rely on subjective measures to report volume changes and outcomes, making product comparison difficult. OBJECTIVES: The authors developed and validated a mathematical model to prospectively calculate and analyze three-dimensional (3D) volumetric changes associated with nasolabial fold augmentation based on human acellular dermis...

The regulations in the recent German Tissue Act have completely changed the working situation for musculoskeletal tissue establishments. According to the requirements of section 20b, section 20c and section 21a AMG it should be possible to maintain local bone banks but centralised regional tissue banks will dominate in the future. The transmission of viral and non-viral infectious pathogens continues to be the most serious of the potential adverse effects of allogenic tissue transplants. Accordingly, tissue banks must focus on comprehensive and robust quality assurance in the areas of donation, testing, processing and preservation...

The Musculoskeletal Transplant Foundation Symposium held in September 2003, in Edinburgh, Scotland provided the opportunity for an orthopaedic surgeon experienced in tissue banking and musculoskeletal allograft transplantation to summarize to orthopaedic colleagues the past and current efforts made by the Food and Drug Administration to ensure the safety of allograft tissues, aspects of tissue banking, concerns of allograft safety and future Food and Drug Administration proposals. The review allows an orthopaedic surgeon an understanding of allograft safety issues and provides information for better informed consent to be obtained by the orthopaedic surgeon from the recipient patient...

Authors of recent reports in the medical literature indicate that allograft-associated infection primarily is attributable to violations of proper tissue processing procedures, and illustrate the need for effective quality assurance systems to avoid transplantation of potentially infectious tissue. I describe the experience of the members of the Musculoskeletal Transplant Foundation with the selection, the processing, and the safety of bone and tissue donors for allograft implantation. In 2002, the Musculoskeletal Transplant Foundation screened 10,497 potential donors, but only 4431 (42%) met stringent criteria for recovery...

A retrospective study and review of the literature was performed on the use of demineralized bone implants for the correction of orbital and craniofacial defects. Demineralized bone implants heal by endochondral osteogenesis, inducing a transformation of local cells, as well as by osteoconduction, similar to autogenous grafts. They induce the chemotaxis and transformation of mesenchymal cells into chondroblasts, followed by ossification. They also act as a scaffold, with bone resorption taking place simultaneous with bone formation...

The placement of oral implants into jaw bone has a high predictability provided an adequate bone volume surrounding the implant is present to ensure primary stability and resistance to functional loading forces after completion of osseointegration. In the distal area of the maxilla, an adequate bone volume is often lacking because of the proximity of the sinus cavities. The aim of this study was to evaluate histologically the simultaneous placement of endosseous implants into the sinus cavity and the surgical elevation of the sinus floor including filling the cavity with different grafting materials...

With the advent of cyclosporine, a powerful and selective immunosuppressant, comes resurgence of a long-sought goal: to transplant modules of allointegumentary/musculoskeletal tissues or components thereof for the repair of peripheral tissue defects. Because these modules of integumentary and/or musculoskeletal tissue are actually composites of various tissues, they are also known as composite tissue allografts. The immediate goal of the studies reviewed herein is to lay the foundation in transplant immunobiology for the clinical exploitation of composite tissue allografts...
