Although ankle arthrodesis is the reference standard for end-stage ankle arthritis, loss of mobility and adjacent joint arthritis are consequences that alternatives to arthrodesis attempt to avoid. The purpose of the present study was to report the clinical results of interpositional arthroplasty using acellular dermal matrix in 4 patients (age 32 to 42 years) for the treatment of advanced ankle osteoarthritis. The primary findings included relief of pain, with improvement in tibiotalar joint range of motion from a mean of 16...

INTRODUCTION: Acellular dermal matrix (ADM) assisted implant-based breast reconstruction (IBBR) has grown in popularity over traditional submuscular techniques. Numerous human, bovine or porcine derived ADMs are available with the type used varying considerably worldwide. Yet, comparative evidence for the efficacy of different ADMs particularly xenogenic is limited. This study directly compares early outcomes of porcine (Strattice™) and bovine (Surgimend™) ADMs in IBBR. METHOD: Retrospective study of sequential experience of immediate IBBR using Strattice or Surgimend ADM...

Acellular dermal matrix allografts (ADMs) have been hypothesized to create a zone of immobile connective tissue (ICT) extending apical to the mucogingival junction (MGJ). This 12-month prospective randomized trial investigated the presence of ICT after the use of two commercially available ADMs with coronally advanced flaps in the treatment of Miller Class I and II recession defects. This study demonstrated that the use of either type of ADM resulted in predictable root coverage and a zone of ICT extending apical to the MGJ by 1...

BACKGROUND: Placement of a closed suction drain is a common cause of patient complaints, such as postoperative pain or discomfort following immediate expander-implant breast reconstruction. This study aims to identify factors that affect drainage volume, time to drain removal, and seroma formation. METHODS: A retrospective chart review of prospectively collected data was conducted on patients who underwent immediate expander-implant breast reconstructions following nipple-sparing or skin-sparing mastectomy without skin excision (nipple areolar complex excision only) between February 2010 and April 2015...

BACKGROUND/AIMS: Bone marrow Mesenchymal stem cells (MSCs) are promising for promoting cutaneous wound healing through reinforcing cellular processes. We evaluated the effect of GFP-tagged MSCs transplantation on skin regeneration in excisional wounds in mice. METHODS: MSCs from GFP-labeled transgenic mice were co-cultured with acellular dermal matrix (ADM) scaffolds, and MSC-ADM scaffolds were transplanted into surgical skin wounds of BALB/c mice. After implantation, the survival and behavior of MSCs were examined by second harmonic generation and two-photon excitation fluorescence imaging, western blotting and DNA amplification and sequencing...

BACKGROUND AND OBJECTIVES: Two staged tissue expander-implant with acellular dermal matrix (TE/I + ADM) and deep inferior epigastric perforator (DIEP) flap are the most common implant and autologous methods of reconstruction in the U.S. Implant-based techniques are disproportionally more popular, partially due to its presumed cost effectiveness. We performed a comprehensive cost analysis to compare TE/I + ADM and DIEP flap. METHODS: A comparative cost analysis of TE/I + ADM and DIEP flap was performed...

BACKGROUND: Nipple sparing mastectomy (NSM) with immediate prosthetic reconstruction is routinely performed due to excellent aesthetic results, and safe oncologic outcomes. Typically, subpectoral expanders are placed, but in select patients, this can lead to significant postoperative pain and animation deformity, due to pectoralis major muscle disinsertion and stretch. Prepectoral reconstruction is a technique that eliminates dissection of the pectoralis major, by placing the prosthesis completely above the muscle with complete acellular dermal matrix (ADM) coverage...

Paraffinoma is a destructive complication of paraffin oil injection, usually associated with massive tissue destruction, thus requiring radical surgery and subsequent complex reconstruction. Although breast and penile paraffinomas have been widely described and their management is quite standardized, paraffinomas of the knee are still rare and only few case reports or small case series are available in the current literature. We describe the case of a 77-year-old man with a large paraffinoma of the right knee that occurred after self-injection of paraffin oil, 58 years before...

This study compared the efficacy and safety of a human acellular dermal matrix (ADM), D-ADM, with a conventional care arm and an active comparator human ADM arm, GJ-ADM, for the treatment of chronic diabetic foot ulcers. The study design was a prospective, randomized controlled trial that enrolled 168 diabetic foot ulcer subjects in 13 centers across 9 states. Subjects in the ADM arms received one application but could receive one additional application of ADM if deemed necessary. Screen failures and early withdrawals left 53 subjects in the D-ADM arm, 56 in the conventional care arm, and 23 in the GJ-ADM arm (2:2:1 ratio)...

INTRODUCTION: Autologous free flaps are the criterion standard for reconstructions of complex soft tissue defects; however, they are limited by donor-site morbidities. The arteriovenous (AV) loop model enables the generation of soft tissue constructs based on acellular dermal matrices with a functional microvasculature and minimal donor site morbidity. The ideal scaffold for AV loop-based tissue engineering has not been determined. METHODS: AV loops were placed into subcutaneous isolation chambers filled with either a collagen-elastin scaffold or a collagen-glycosaminoglycan scaffold in the thighs of rats...

BACKGROUND: A split-thickness skin graft (STSG) is performed to cover a large full-thickness skin defect. Esthetic and functional deficits can result, and many studies have sought to overcome them. This study compared the effectiveness of the acellular dermal matrix (ADM) graft and STSG concerning esthetic and functional effectiveness of ADM on scar quality. METHODS: Of the patients who underwent anterolateral thigh free flap from 2011 to 2015, patients who received skin graft only (n = 10) or skin graft with ADM (n = 20) for coverage of the donor site were enrolled...

BACKGROUND: Heel reconstruction represents a challenge for all plastic surgeons due to the anatomical and functional features of this weight-bearing area. In the last decade a combined use of acellular dermal matrices and skin grafts has been proposed as a reliable and less invasive alternative for complex wound management; nevertheless only a few cases have been reported in the literature. METHODS: We describe the long-term outcome of 2 cases of severe degloving trauma of the plantar region with massive soft tissue defects of the foot, that underwent surgical reconstruction with artificial dermis and skin grafts...

Acellular dermal matrix (ADM) such as Alloderm(®) is sometimes used in tissue reconstruction in primary and reconstructive breast surgeries. As ADM is incorporated into the native tissues, the evolving imaging findings that would correlate with varying degrees of host migration and neoangiogenesis into the matrix can be challenging to recognize. In the setting of a palpable or clinical area of concern after breast reconstructive surgery following breast cancer, confident diagnosis of a mass representing ADM rather than recurring or developing disease can be challenging...

Kyeong-Tae Lee, Goo-Hyun Mun
BACKGROUND: The current diversity of the available acellular dermal matrix (ADM) materials for implant-based breast reconstruction raises the issue of whether there are any differences in postoperative outcomes according to the kind of ADM used. The present meta-analysis aimed to investigate whether choice of ADM products can affect outcomes. METHODS: Studies that used multiple kinds of ADM products for implant-based breast reconstruction and compared outcomes between them were searched...

PURPOSE: Controversy exists regarding complications associated with the use of acellular dermal matrix (ADM). This likely stems from the heterogeneous and unmatched patient characteristics in study groups. The purpose of this study was to analyze complications in a matched cohort to identify whether ADM use increased postoperative complications of the first-stage immediate expander-implant breast reconstructions. METHODS: A retrospective matched-cohort study was performed...
