  • Oslo Sports Trauma Research Center - 132 - Injury risk on artificial turf in youth football
    has been concern whether there is an increased risk of injury related to increased training and match exposure to artificial turf Thus the aim of this study was to examine whether there is a difference in injury risk playing on natural turf compared to second and third generation artificial turf in youth football This prospective cohort study was carried out during Norway Cup 2005 2008 The injury registration included the 11 a side classes which comprised all the players 13 to 19 years of age of both genders In total the study comprised approx 4 000 teams 60 000 players and 8 000 matches All injuries both acute and overuse related were registered and the injury definition was all injuries painful conditions or physical complaints which occur during the match even if the player is able to continue to play The injury registration involved the referee who prior to each match handed out an injury record form to each team The coaches were instructed to fill out the form during the match Immediately after each match the form was collected by the referee and handed over to the technical headquarters along with the match score card This study will tell

  • Oslo Sports Trauma Research Center - 128 - Ultrasound-guided sclerosis of neovessels in painful chronic patellar tendinopathy – a prospective study
    randomized controlled study with sclerosing the vessels in patients with the diagnosis of Jumper s knee has shown promising results and by this prospective study we want to improve knowledge of the treatment options for patellar tendinopathy Specifically this study will investigate if sclerosing the neovessels would affect the level of patellar tendon pain and knee function in a large group of patients with patellar tendinopathy Jumper s knee affects athletes in many sports and elite jumping athletes appear to be the most susceptible The high prevalence long duration of symptoms and low function scores suggest that in some sports patellar tendinopathy may cause at least as much impairment for athletic performance as acute knee injuries Based on studies on Achilles tendinopathy and patellar tendinopathy our hypothesis is that the vessels and possibly also the nerves accompanying the vessels are involved in the pain mechanism in chronic painful Achilles and patellar tendinosis A randomized controlled study showed promising results of sclerosing treatment on patients with patellar tendinopathy This prospective study will recruit patients with jumper s knee from the clinics cooperating in this project Patients with patellar tendinopathy and neovascularisation will receive up to a maximum of five ultrasound guided

  • Oslo Sports Trauma Research Center - 194 - Focal cartilage defects in the knee and life quality
    validated global knee score suitable for comparison of patients with knee complaints attributable to different causes Hypothesis Complaints because of localized cartilage defects in the knee reduce quality of life measured by KOOS to a different extent than those due to anterior cruciate ligament deficiency and osteoarthritis when comparing patients within the working population scheduled for surgery Methods Previously registered KOOS baseline data on patients enrolled in different knee treatment

  • Oslo Sports Trauma Research Center - 138 - Validation of the visual inspection approach in video analysis
    Although our group has recently developed a more sophisticated method to estimate joint kinetics from video sequences this is too time consuming to apply on a large number of injury tapes Simple visual assessment of joint kinematics may therefore be an alternative if the number of videos to be analyzed is large However the accuracy and precision of such analyses are unknown Therefore the purpose of this study was to test the accuracy and precision of researchers to estimate kinematics from video sequences of situations that typically lead to ACL injuries We also tested if accuracy and precision could be improved by a training program Methods Using a traditional surface marker based infrared 240 Hz 3D motion analysis system we recorded running and cutting trials from three test subjects Six international researchers were asked to provide estimates of kinematic variables from 27 video composites from one two or three ordinary cameras systematically varying viewing angles and time point of analysis The analysts thereafter went through a training program where 35 similar composites were analyzed and feedback on the kinematics as measured by the 3D motion analysis system was provided on a group basis Finally the pre test was repeated to

  • Oslo Sports Trauma Research Center - 139 - Mechanisms of ACL injury inbasketball: video analysis of 39 cases
    et al who attempted to quantify the joint kinematics most descriptions were qualitative and the results are difficult to compare across studies Furthermore apart from one study on team handball previous video analyses have only investigated a limited number of cases from mixed sports The purpose of this study was therefore to describe the mechanisms of ACL injury in basketball based on videos of injury situations Methods Six international experts performed visual inspection analyses of 39 videos 17 male 22 female of ACL injury situations from high school college and professional basketball games Two pre defined time points were analyzed initial ground contact and 50 ms later The analysts were asked to assess the playing situation player behaviour and joint kinematics Results Results There was contact at the assumed time of injury in 11 of the 39 cases five males six females Four of these cases were direct blows to the knee all in men Eleven of the 22 female cases collided or were pushed by an opponent prior to the time of injury The estimated time of injury based on the group median ranged between 17 and 50 ms after initial ground contact The mean knee flexion angle was

  • Oslo Sports Trauma Research Center - 126 - Preventing injuries in female youth football-a randomized controlled study
    hamstrings groin and ankle injuries serious knee injuries such as anterior cruciate ligament ACL injuries are a particular concern in female soccer However a study with a sufficient number of players has not yet been carried out Thus predicting the injury rate among junior players is difficult F MARC 11 is a specific warm up program that has recently been designed by an expert group within F MARC FIFA Medical Assessment Research Center in order to prevent the four most common types of injuries in soccer i e injuries to the ankles knees groin and hamstrings respectively The program includes 10 exercises It is time efficient requires little equipment and it is easy to carry out regardless of age and skill level The program is designed to be a part of the warm up period at each training session and includes stabilization exercises for abdomen back and hip strength training for thigh and hamstrings muscles and also varying balance and jumping exercises This study will provide us with detailed information on the injury panorama in this group of young female soccer players and answer the question whether we can reduce the risk for common and serious injuries in soccer Aim
