INTRODUCTION: Surgical instrumentation is now available to facilitate wound debridement. The 2 primary options involve different energy applications, but both have the potential to spray. The Versajet II (Smith & Nephew, London, UK) utilizes a high-powered water jet to disrupt tissue and remove debris by means of the Venturi effect. The SonicVac (Misonix, Farmingdale, NY) is a direct-contact, low-frequency ultrasound debriding device. It delivers a high-energy ultrasound to a wound surface via a fluid medium, causing bubble cavitation, a physical effect of rapid pressure waves causing bubbles to form and implode that releases mechanical energy...

BACKGROUND: Reducing polyethylene (PE) wear by increasing the cross-linking encouraged surgeons to hope for increased total knee arthroplasty (TKA) survival rates. Different methods of manufacturing cross-linked polyethylene (XLPE) were introduced, following promising in vitro results. Is there a measurable effect of cross-linking on TKA survival? METHODS: A registry study was conducted, focusing on fixed tibial inserts in primary TKA. Conventional PE represented 87% of the liners, 10% were cross-linked and 2% were antioxidant PE...

BACKGROUND: In young patients with osteonecrosis of the femoral head (ONFH), short-stem total hip arthroplasty (THA) could allow a potential advantage in preserving metaphyseal bone-stock, when revision surgery might become necessary. However, only a few studies have evaluated the outcome of short-stem THAs in ONFH. We reviewed the prospectively collected data of a cementless partial neck-retaining short-stem with ceramic-on-ceramic bearings in ONFH patients. METHODS: Thirty patients (37 hips) younger than 60 years (mean age at surgery, 51...

Background Arthrosis of the knee is a common problem in Germany that is often treated with arthroplasty. To support the orthopaedic surgeon, person-matched instruments (PMI) are available from several providers. In this study we investigated the clinical and radiological outcome of the use of the PMI Visionaire(™) (Smith&Nephew). Furthermore, we investigated the influence of operative experience of the orthopaedic surgeon on the clinical and radiological results. Time in the operating room (OR) was identified as a parameter for cost effectiveness even during training to become an orthopaedic surgeon...

BACKGROUND: A new polyurethane foam dressing impregnated with 3% povidone-iodine (Betafoam; Genewell, Seoul, Korea) was recently developed based on the hypothesis that its physical properties, including improved moisture-retention capacity and antimicrobial activity, are at least as good as those achieved with the current foam dressings that contain silver, but also associated with reduced cost and cytotoxicity to host cells. The purpose of this in vitro study was to evaluate the efficacy of Betafoam by comparing its physical properties, antimicrobial activity, and cytotoxicity with those of 3 silver foam dressings (Allevyn-Ag [Smith & Nephew, Hull, United Kingdom]; Mepilex-Ag [Mölnlycke Health Care, Gothenburg, Sweden]; and PolyMem-Ag [Ferris MFG Corp, Burr Ridge, Illinois]) used worldwide...

BACKGROUND: A fast and stable wound closure is important, especially for extended and unstable wounds found after burn injuries. Growth can regulate a variety of cellular processes, including those involved in wound healing. Growth differentiation factor 5 (GDF-5) can accelerate fibroblast cell migration, cell proliferation, and collagen synthesis, which are essential for wound healing. Nevertheless, no standardized evaluation of the effect of GDF-5 on the healing of full-thickness wounds has been published to date...

BACKGROUND: The use of bipolar electrodes for arthroscopic procedures carries a theoretical ex vivo risk of inducing burn injuries. Few studies have measured the in vivo temperatures produced by bipolar electrodes during arthroscopy, and their results are conflicting. The objective of this study was to evaluate the temperature profile within the subacromial space during shoulder arthroscopy with two different electrode systems. HYPOTHESIS: The primary hypothesis was that the two electrode systems produced similar temperature variations and peak temperatures...
