using platelet rich plasma to treat jumper s knees exploring the effect of a second closely timed Infiltration
Journal of Science and Medicine in Sport, 2016Co-Authors: Jeanfrancois Kaux, Jeanlouis Croisier, Benedicte Forthomme, Le C Goff, Frederic Buhler, Betty Savanier, Sandra Delcour, Andre Gothot, Jeanmichel CrielaardAbstract:Abstract Objectives Some clinical series have evaluated the effect of platelet-rich plasma (PRP) in the treatment of proximal patellar tendinopathy. Although it is possible that a single infiltrative administration may prove to be an effective treatment for this indication, most of the existing studies evaluated the effects of two or three successive Infiltrations. The aim of this study was to evaluate whether two Infiltrations of PRP proves more effective than a single treatment. Design Prospective, randomized and comparative study of level 2. Methods Twenty patients suffering from chronic proximal patellar tendinopathy were enrolled into the study and split into two randomized groups (one or two Infiltrations of PRP, respectively). The 3-month follow-up evaluation consisted of VAS, IKDC and VISA-P scores, along with algometer, isokinetic and ultrasounds evaluations. After 1 year, subjects were contacted to define their functional evolution. Results The concentration of the PRP used for each Infiltration was similar in both groups, and contained no red or white cells. Results revealed no difference in treatment efficacy between the groups. Conclusions The comparison between one or two Infiltrations of PRP did not reveal any difference between the two groups at short to mid term. A second closely-timed Infiltration of PRP to treat proximal patellar tendinopathies is not necessary to improve the efficacy of this treatment in the short term.

description of a standardized rehabilitation program based on sub maximal eccentric following a platelet rich plasma Infiltration for jumper s knee
Muscles ligaments and tendons journal, 2014Co-Authors: Jeanfrancois Kaux, Benedicte Forthomme, Jeanmichel Crielaard, Mariehelene Namurois, Philippe Bauvir, Nathalie Defawe, Francois Delvaux, Cedric Lehance, Jeanlouis CroisierAbstract:Introduction. Different series emphasized the necessity of rehabilitation program after Infiltration of platelet-rich plasma (PRP) in case of tendino - pathy. However, most of them describe only briefly the reeducation protocol and these programs vary. Our aim was to extensively describe a specific standardized rehabilitation program. Methods. After a review of literature of post-PRP Infiltration protocols, we had developed a standardized rehabilitation protocol. This protocol was evaluated by 30 subjects with chronic jumper’s knee who. A standardised progressive sub-maximal eccentric program supervised by a physical therapist for 6 weeks was started 1 week post-Infiltration. The patient benefited also from electromyostimulation, isometric strengthening and stretching of the quadriceps, cycloergometer and cryotherapy. After the supervised program, the patient had to make an auto-reeducation added to the reathletisation protocol for 6 more weeks which was followed by maintenance exercises up to 1 year. The assessments were made using a VAS, IKDC and VISA-P scores. Results. The VAS, IKDC and VISA-P scores decreased very significantly with time. The compliance to auto-reeducation was good. Conclusions. We proposed a simple and efficient protocol based on sub-maximal eccentric reeducation to add to PRP Infiltrations in case of patellar tendinopathy

effect of pyrolysis temperature on the microstructure and capillary Infiltration behavior of carbon carbon composites
Ceramics International, 2018Co-Authors: Xiaojun Wu, Nico Langhof, Rebecca Habath, Walter Dr. Krenkel, Franziska LenzAbstract:Abstract Carbon fiber fabric reinforced plastics were pyrolyzed at temperatures between 900 °C and 1600 °C to convert them into carbon/carbon (C/C) composites. The effects of pyrolysis temperatures on the microstructure, mechanical properties, and especially on the capillary Infiltration behavior of C/C composites, suitable for liquid silicon Infiltration (LSI), were investigated. The porosity of these C/C composites shows a decreasing trend with increasing pyrolysis temperature. The established model can explains the pyrolysis mechanism and the Infiltration behaviors. Within the initial stage, the capillary Infiltration rate of C/C composites with the model fluid water increases rapidly. In the second stage, where thermal imaging indicates that water has reached the top area of the plates at the initial stage. Capillary Infiltration rate, based on water Infiltration experiments mass increase, decreases because the shrinkage of micro-delamination take place at higher pyrolysis temperature. In combination with LSI results, a model for the capillary Infiltration behavior of C/C is proposed.
