Tendons heal through three different overlapping phases; the inflammatory, proliferative and remodeling phase. Many studies have investigated what factors influence healing of tendons. However, little was known about inflammation and the immune cells present during Achilles tendon healing by the time this thesis started. We developed a flow cytometry method for our rat model of tendon healing, which enabled us to study different leukocyte subpopulations during Achilles tendon healing. The general aim of this thesis was to understand more about inflammation and the immune cell populations present during tendon healing and how the immune cell composition changes during normal tendon healing. Moreover, we investigated how different factors that are known to influence tendon healing affected the composition of the immune cell population. First, we described the immune cells during the time course of tendon healing focusing on different subpopulations of macrophages and T cells. Then, we studied how these cells were influenced by reduced mechanical loading. Mechanical loading prolonged the presence of M1 macrophages and delayed the switch to regulatory T cells and M2 macrophages compared to reduced mechanical loading. Next, the effect of nonsteroidal anti-inflammatory drugs (NSAIDs) on the leukocyte composition revealed that, even though NSAIDs influence the mechanical properties of healing tendon, this effect was not mediated via changes in the leukocyte sub-populations during early and mid-time tendon healing. Further, the effect of corticosteroids during the inflammatory and remodeling phases of tendon healing was an improved healing of tendons and a reduction of CD8a T cells when corticosteroid was administered after the inflammatory phase. Lastly, we investigated if impairment of tendon healing by NSAIDs was related to mechanotransduction or microdamage during mechanical loading and showed that NSAIDs impair tendon healing by reducing the response to microdamage. In conclusion, these studies show that inflammation plays an important role during Achilles tendon healing, and factors that influence healing can also alter the presence or polarization of immune cell populations.

Biomechanics of Tendons and Ligaments: Tissue Reconstruction looks at the structure and function of tendons and ligaments. Biological and synthetic biomaterials for their reconstruction and regeneration are reviewed, and their biomechanical performance is discussed. Regeneration tendons and ligaments are soft connective tissues which are essential for the biomechanical function of the skeletal system. These tissues are often prone to injuries which can range from repetition and overuse, to tears and ruptures. Understanding the biomechanical properties of ligaments and tendons is essential for their repair and regeneration. - Contains systematic coverage on how both healthy and injured tendons and ligaments work - Includes coverage of repair and regeneration strategies for tendons and ligaments - Presents an Interdisciplinary analysis on the topic

This book presents the latest advances in the field of regenerative medicine in plastic surgery. It is the first authoritative reference documenting all the ways that plastic surgical practice and regenerative medicine science overlap or provide a road map for the future of both specialties. The Editors have provided a valuable service by gathering in one place the leading voices in these two fields in clear and concise manner.The first part introduces readers to essential principles of skin and soft tissue regeneration, e.g. the possibility of using mesenchymal stem cells for wound healing. Since bone serves as a supportive tissue in most of the body, bone regeneration is an important aspect of regenerative medicine; accordingly, the second part discusses the novel bone implants, activated bone grafts and bone tissue engineering. The book’s third part, focusing on cartilage regeneration, includes chapters on e.g. stem cells and ear regeneration. In turn, part four addresses muscle and tendon regeneration: from tendon to bone and tendon to muscle, as well as aging in the realm of muscle regeneration. Lastly, part five highlights nerve regeneration, deepening surgeons’ knowledge to help them successfully treat injuries to the peripheral neural system. Written by leading experts this book is an invaluable resource for researchers, students, beginners and experienced clinicians in a range of specialties. "With beautiful clinical images and artwork, this book will be a central companion to both practicing plastic surgeons who wish to remain abreast of oncoming technologic advances and regenerative medicine researchers who wish to understand the current state of the art of surgical reconstruction." - Geoffrey C. Gurtner, MD, FACS Johnson and Johnson Distinguished Professor of Surgery Professor (by courtesy) of Bioengineering and Materials Science Inaugural Vice Chairman of Surgery for Innovation Stanford University School of Medicine

Every year workers' low-back, hand, and arm problems lead to time away from jobs and reduce the nation's economic productivity. The connection of these problems to workplace activities-from carrying boxes to lifting patients to pounding computer keyboards-is the subject of major disagreements among workers, employers, advocacy groups, and researchers. Musculoskeletal Disorders and the Workplace examines the scientific basis for connecting musculoskeletal disorders with the workplace, considering people, job tasks, and work environments. A multidisciplinary panel draws conclusions about the likelihood of causal links and the effectiveness of various intervention strategies. The panel also offers recommendations for what actions can be considered on the basis of current information and for closing information gaps. This book presents the latest information on the prevalence, incidence, and costs of musculoskeletal disorders and identifies factors that influence injury reporting. It reviews the broad scope of evidence: epidemiological studies of physical and psychosocial variables, basic biology, biomechanics, and physical and behavioral responses to stress. Given the magnitude of the problem-approximately 1 million people miss some work each year-and the current trends in workplace practices, this volume will be a must for advocates for workplace health, policy makers, employers, employees, medical professionals, engineers, lawyers, and labor officials.
