  • Oslo Sports Trauma Research Center - 076 - The prevalence of jumpers knee among elite Norwegian athletes
    with jumpers knee in different sports Therefore we will perform an epidemiological study of the prevalence in different sports As a part of the study the exercise load will be evaluated with regard to the prevalence of jumpers knee in the different sports As another part of the study we will evaluate the reproducibility of history taking and clinical examination with regard to interobserver variation The study will be performed

  • Oslo Sports Trauma Research Center - 075 - A randomized study comparing outcome after standard surgical treatment and eccentric training among athletes with jumpers knee
    Standard treatment based on experience has so far consisted of different kinds of physical therapy combined with NSAID If this treatment has not given satisfactory results different kinds of surgical treatments have been proposed The scientific basis of these different treatments is very sparse The studies that have been published are of rather low quality and the internal and external validity are very uncertain Coleman 1999 In a recent publication by Alfredsson eccentric training gave very good results in a small number of athletes with achilles tendinosis Alfredsson 1998 The study is designed as a prospective randomized multicenter study comparing treatment response between surgical treatment and eccentric training among athletes with jumpers knee The surgical treatment will consist of open exploration of the ligament and excision of pathologic paratenon and ligament tissue The postoperative rehab program will be the same as in the group treated with eccentric training The eccentric training will consist of a 12 weeks training program with increasing loads The exercises are described in details in the project description Outcome measures are as follows VISA score Visentini 1998 reflecting the seriousness of the disease and a validated method to observe changes with time MRI at inclusion and

  • Oslo Sports Trauma Research Center - 109 - Injury mechanisms for head injuries in football
    injuries are serious and lead to acute traumatic brain injury with permanent disability Furthermore fatal neurologic injuries in football have also been reported Hughes 74 In addition to acute traumatic brain injury chronic traumatic brain injury is of concern in football The objective of this study is to analyze the injury mechanisms e g whether head to head elbow head or ball in the head are the main high risk

  • Oslo Sports Trauma Research Center - 043 - The role of the referee: a video analysis of the interpretation of the rules of football in injury-risk situations in professional football
    in foul play whereas the rest of the injuries occurred where no foul play was adjudged by the referee to have taken place In all these non foul situations in which injury resulted at least 60 still involved player to player contact Ekstrand Gillquist 1983 found corresponding results in lower division male soccer showing that 23 of traumatic game injuries were caused by foul play In modern soccer the number of fouls seems to be increasing The impact of the referee on the number of faults and indirectly on the injury rate is therefore more important than previously The role of the referee as an extrinsic risk factor of soccer injuries has so far never been studied This project will focus on foul play the adjudgment of the referee according to the current interpretation of the soccer rules in elite soccer There may be a potential for reducing the injuries by educating the referees and players on following the rules of the game In addition analysis of called and non called fouls may result in changes of the enforcement of todays rules in the game Material and methods All video tapes 182 from Norwegian elite division games in year 2000
