  • Oslo Sports Trauma Research Center - 066 - Clinical, functional and radiological outcome 6-10 years after ACL-injuries in team handball players - a follow-up study
    The present study is based on a patient population from a previous study Myklebust et al 1997 In this study all ACL injuries were prospectively registered in the three upper divisions in Norwegian team handball during the 1989 through 1991 seasons and a total of 87 ACL injuries were found Some of them were treated operatively and some non operatively These players will be followed up 6 10 years after their initial injury to examine the consequences of an ACL injury The aims of the study are to evaluate The return rate to sport at pre injury level The number of players with re injuries after ACL reconstruction The clinical outcome 6 10 years after injury in the operatively treated group and the non operatively treated group The prevalence of radiological changes and their relationship to the clinical outcome The relationship between clinical outcome and findings at clinical examination This is a follow up study of a cohort of team handball players with a previous ACL injury The ACL injured players from the investigation in 1989 1991 have been invited to take part We have followed this group 6 10 years after their initial ACL injury The investigation group consists of 3 persons two physical therapists PT and one physician The players who lived near Oslo came to Rikshospitalet for tests The investigation group travelled to three others places in Norway for testing players The examination of the players consist of the following tests questionnaire KT 1000 arthrometer clinical examination muscle performance test medical journal IKDC score Lysholm and Tegner scores functional knee tests x ray Results Fifty seven players were treated operatively and 22 non operatively In the operatively treated group 33 58 returned to team handball at their pre injury level compared with 18 82 in the non

  • Oslo Sports Trauma Research Center - 059 - On-slope evaluation of release bindings for World Cup freestyle skiers
    incidence of such injuries has declined considerably Previous studies have shown however that alpine racing skiers adjusted their toe bindings to a setting value 45 above International Organisation of Standardisation ISO recommended values The aim of this study was to estimate the torque at which the toe bindings of the World Cup mogul skiers actually release and to compare these values to both the ISO recommendations for binding adjustment and to the setting values indicated on the scale of the skiers bindings We also wanted to question the skiers familiarity with the ISO recommended setting values Results The setting values as indicated on the scale of the toe bindings of the 54 World Cup freestyle mogul skiers were 92 range 18 175 higher than the ISO International Organization of Standardization recommended setting values The estimated torque at which the bindings actually released when tested on slope with a testing machine was even 15 range 23 143 higher than the setting value indicated decreasing to 7 range 22 88 after the first release Only 4 of the 54 skiers suggested a setting value within a range of 10 of the ISO recommendations when asked what they believed was the ISO recommended

  • Oslo Sports Trauma Research Center - 034 - Ankle injuries in volleyball: A retrospective cohort study
    exact mechanisms of injury and suggest possible prevention strategies In volleyball the opposing players are separated by the net and the center line and this should reduce the risk of contact injuries compared to other team sports But according to FIVB rules players from both teams are allowed to step on the 5 cm wide center line and into the half court of the opponent provided that some part of the penetrating foot feet remains either in contact with or directly above the center line Thus there is a zone of about 50 cm width under the net where players from opposing teams may come into conflict when landing after attacking or blocking Also players from the same team usually try to form a block of two or even three players jumping simultaneously to stop the opponent attack We would therefore expect many of the ankle injuries to stem from landing on the foot of an opponent or teammate The purpose of the present study was to examine the incidence and mechanisms of ankle inversion injuries in a well trained and skilled population of volleyball players The study was designed as a retrospective cohort study where coaches and players in the top two divisions of the Norwegian Volleyball Federation were interviewed after the 1991 1992 season about ankle inversion injuries that had occurred The study was limited to acute ankle inversion injuries that caused an absence of one or more days from training or match play Results A total of 63 injuries were found among 318 players during 60612 hours of training and 928 matches The total injury rate was 0 9 0 12 per 1000 player hours 0 7 0 11 during training and 2 6 0 56 during match play The relative risk of injury during match play

  • Oslo Sports Trauma Research Center - 072 - Relationship between symptoms of jumper`s knee and the ultrasound characteristics of the patellar tendon among high level male volleyball players
    described as the syndrome of jumper s knee by Blazina et al Numerous histological and soft tissue imaging studies have shown tendon abnormalities in patients with jumper s knee sometimes explained as the consequences of a non healed or insufficiently healed partial patellar tendon tear although the pathophysiology of this tendon disorder is unknown Recent studies have shown that ultrasound is highly accurate in showing tendon tears later confirmed during surgery in athletes with disabling patellar tendon pain but to our knowledge only one study has compared the clinical diagnosis of jumper s knee with ultrasound findings in players with less serious symptoms The purpose of this study was to examine and compare the ultrasound characteristics of the patellar tendon in two groups of high level volleyball players one asymptomatic group and one group with symptoms of jumper s knee Results Of the 47 male elite players that were examined 25 were diagnosed with current and 7 with previous symptoms of jumpers knee as determined by clinical examination and interview Since some players had bilateral problems there were 34 knees with current problems and nine with previous problems Seven of the 30 knees with a clinical diagnosis of jumpers knee

  • Oslo Sports Trauma Research Center - 073 - Dynamic characteristics of the extensor apparatus among volleyball players with jumper`s knee - a cohort study
    where athletes are required to perform jumping actions or rapid accelerations thereby placing high demands on the knee extensor apparatus Our understanding of the causes of partial tendon ruptures of the patellar tendon is incomplete Training volume and the floor surface are extrinsic factors which correlate positively with the prevalence of jumper s knee Data on intrinsic factors are conflicting and mostly related to static biomechanical parameters In a recent case control study we evaluated some dynamic characteristics of the leg extensor apparatus and the results suggest that players with jumper s knee perform better on jump tests than healthy controls especially tests involving eccentric work The purpose of the present study was to examine the leg extensor characteristics in a larger cohort of players using a more comprehensive jump and strength testing program To study the dynamic characteristics of the extensor apparatus the players performed a test program consisted of a standing jump a countermovement jump a 15 second rebound jump test a standing jump with a 20 kg load and a standing jump with a load corresponding to one half of the subjects body weight Results The study was carried out during an international volleyball tournament in Oslo Norway The six Norwegian teams that participated in the men s elite class in the tournament were invited to take part in the study These were amateur teams which otherwise compete in the top division of the Norwegian Volleyball Federation leagues The teams consisted of 53 players and 47 of these 87 consented to take part in an interview clinical examination and a series of standardized jump and power tests Of the 47 players participating in the study 24 players 51 0 were clinically diagnosed with current jumper s knee affecting at least one side Twenty players 42 6 had
