(2011), Problems and complications of surgical techniques for treatment of full-thickness cartilage defects. Zeitschrift fur Orthopadie und Unfallchirurgie, 149 (1), 45-51. Abstract: Aim: There has been great progress concerning the surgical treatment of full-thickness cartilage defects within recent years. Surgical techniques such as arthroscopic microfracturing (MF), autologous osteochondral transplantation (OCT) and autologous chondrocyte implantation (ACI) have been introduced and, by using these techniques, reliable and satisfying clinical results can be achieved. Nevertheless, there are also technique-related problems and characteristic complications of all surgical techniques in the field of cartilage repair. Knowledge of these complications is essential for every surgeon using these techniques. The aim of the present article is to give an overview concerning technique-associated and characteristic complications of the most common cartilage repair techniques including arthroscopic microfracturing, autologous osteochondral transplantation and autologous chondrocyte implantation (ACI). Methods: In order to identify relevant literature concerning complications following cartilage repair, medical databases including “MEDLINE”, “ovid” and “Web of Science” were searched for the terms “autologous chondrocyte implantation”, “autologous chondrocyte transplantation”, “microfracture”, “osteochondral transplantation”, “cartilage repair”, “cartilage defect” and “complications” in October 2009. The present publication represents a non-systematic review including publications which were considered relevant for describing charateristic complications and adverse events in surgical techniques used for cartilage repair. Results: Although the number of studies describing complications and adverse events following surgical cartilage repair studies is limited, for all techniques included in the present review (arthroscopic microfracturing, autologous osteochondral transplantation and autologous chondrocyte implantation) technique-associated and characteristic complications could be identified. While regenerative tissue following microfracturing seems to be limited in terms of durability, intralesional bone formation and elevation of the subchondral bone plate seem to be characteristic problems of this technique. Harvest morbidity, degeneration of the surrounding cartilage, necrosis of the transplanted cylinders and a lack of integration of the cartilage into the surrounding cartilage seem to be related to the transplantation of osteochondral cylinders (OATS/OCT), while hypertrophic regenerative cartilage, disturbed fusion into the adjacent cartilage, delamination and insufficient cartilage regeneration are associated with the autologous chondrocyte implantation (ACI). Conclusion: The present paper identifies technique-associated complications for the most common surgical techniques used for cartilage repair. Even if the clinical relevance of the complications described in the current article has not been investigated to its fullest extent, the awareness of these characteristic complications is essential in order to avoid them whenever possible or to develop standardised treatment regimes for these problems. This needs to be addressed in further investigations.

(2007), As mirrored by the journal: Themes and trends of educational psychology in the years 2005 to 2007. Zeitschrift fur Padagogische Psychologie, 21 (3-4), 195-202. Abstract: From 2008 on Jens Moeller will take over from Detlev Leutner the role of the editor of the German Journal of Educational Psychology. This gives the reason to analyse figures, facts and trends of contemporary educational psychology as they are mirrored in the articles of the Journal. It turns out that the Journal enjoys great and increasing popularity among authors, leading to an increase of manuscript submissions and, thus, to an increasing rejection rate. Analysing the Journal’s impact factor shows that its variability over time is due to the variability of self-citations (i.e., citations from the Journal to the Journal), not to the variability of non self-citations (i.e., citations from other journals to the Journal). The non-self-citations represent a rather stable component of the Journal’s impact factor that amounts to 0.50 impact-factor points which is quite large relative to other German journals in the field of educational psychology. Concerning research themes, there is a strong trend favouring articles on << self-concept, motivation, and emotion in the learning process >> to the disadvantage of articles on << leaming and instruction >> and << educational psychological research on training programs >>. Overall, the German Journal of Educational Psychology seems to be in a good position for meeting future challenges.

Zeitschrift fur Padagogische Psychologie, 24 (3-4), 163-169. Abstract: From 2010 on Oliver Dickhauser will take over the role of the editor of the German Journal of Educational Psychology from Jens Moller. This gives the reason to analyze figures, facts and trends of contemporary educational psychology as they are mirrored in the articles of the Journal. It turns out that the Journal enjoys great popularity among authors, leading to a stable number of manuscript submissions. Analyzing the Journal’s impact factor shows that its variability over time is mostly due to the variability of self-citations (i.e., citations from the Journal to the Journal). Notably, the number of non-self-citations (i.e., citations from other journals to the Journal) increased to 0.72 in 2009. Concerning research themes, there is a trend favoring articles on “learning and instruction” (with a high numbers of papers on teaching and teachers) depending on corresponding special issues of the Journal. Overall, the German Journal of Educational Psychology seems to be in a good position for meeting future challenges.
