T1  - Structure-Function relationships of equine menisci
JF  - PLoS ONE
N2  - Meniscal pathologies are among the most common injuries of the femorotibial joint in both human and equine patients. Pathological forces and ensuing injuries of the cranial horn of the equine medial meniscus are considered analogous to those observed in the human posterior medial horn. Biomechanical properties of human menisci are site-and depth-specific. However, the influence of equine meniscus topography and composition on its biomechanical properties is yet unknown. A better understanding of equine meniscus composition and biomechanics could advance not only veterinary therapies for meniscus degeneration or injuries, but also further substantiate the horse as suitable translational animal model for (human) meniscus tissue engineering. Therefore, the aim of this study was to investigate the composition and structure of the equine knee meniscus in a site-and age-specific manner and their relationship with potential site-specific biomechanical properties. The meniscus architecture was investigated histologically. Biomechanical testing included evaluation of the shore hardness (SH), stiffness and energy loss of the menisci. The SH was found to be subjected to both age and site-specific changes, with an overall higher SH of the tibial meniscus surface and increase in SH with age. Stiffness and energy loss showed neither site nor age related significant differences. The macroscopic and histologic similarities between equine and human menisci described in this study, support continued research in this field.

T1  - Verletzungen und Schäden bei Breiten- und Leistungssportlern des  modernen Fechtsports: eine Langzeitanalyse
T1  - Acute and chronic injuries in modern fencing – A long-term evaluation
N2  - There are only a few prospective studies about injury characteristics in modern fencing. The study aimed to identify the patterns of acute and chronic injuries in fencing. In retrospective questionnaire fencers were questioned about acute injuries and chronic health problems related to modern fencing. Additionally, fencers were questioned in a prospective observational study over a period of 18 months. Elite fencers as well as amateurs were part of the study. The study examined the frequency, location, severity, and the causes of incidences and possible interrelations.  Acute and chronic injuries in fencing occur frequently. They mostly affect the lower extremities. Sprains and strains are the leading acute injuries, while chronic injuries include mostly tendinopathies and chronic pain. The injury rate and pattern differ between gender and performance level. Since typical injury causes can be identified, there can be valuable preventive measures concluded.
N2  - Prospektive Studien zu Verletzungsmustern und deren Ursachen im modernen Fechtsport gibt es nur wenige. Das Ziel dieser Studie war es, typische Verletzungen und Schäden aufzudecken, sowie deren Entstehungsmuster, um potenzielle Präventionsmaßnahmen ableiten zu können. Wir befragten 353 Teilnehmer aus ganz Deutschland retrospektiv, von denen wir 163 Fechter für regelmäßige Follow-Ups über 18 Monate gewinnen konnten. Anschließend erfolgte die Analyse der Gesamtpopulation und im Vergleich zwischen den Disziplinen, Geschlechtern und Leistungsklassen. Das Risiko für Verletzungen und Schäden im Fechtsport ist vergleichsweise niedrig. Die meisten Verletzungen betrafen die untere Extremität. Dabei war vor allem der Bänder- und Muskelapparat von Sprunggelenk, Oberschenkel und Knie gefährdet. Verletzungen entstanden besonders im Rahmen des Ausfalles. Typische chron. Ereignisse im Fechtsport sind Entzündungen und Schmerzen der unteren Extremität. Das Risiko unterscheidet sich signifikant zwischen den Leistungsklassen sowie den Geschlechtern. Es konnten typische Risikofaktoren und Verletzungsmechanismen identifiziert werden. Daraus lassen sich sinnvolle Präventionsmaßnahmen ableiten.
