Background and Study Aim: This study determined the kinds of injuries occurring in judo. The first aim of this study is a knowledge about achievement-orientated training of competing athletes about their history of knee injuries and about the individual special throwing technique (STT). The second aim is to answer the question whether a correlation exists between STT (with special emphasis on seoi nage and uchi mata) and types of knee joint injuries.
Material and Methods: For data collection an anonymized questionnaire was used. The questionnaires of 260 competition-oriented German judoka were analyzed: a mean age of 26.5 ± 9,1 years, had a body height of 175.0 ± 13,6 cm, and a body weight of 76,8 ± 15,9 kg. They trained for 16.5 ± 8.2 years with a frequency of 3.5 ± 2.7 times a week.
Results: The knee joint is the most injury affected region in judo (p<0.05). There was no significant correlation between the own special throwing technique of a judoka and the occurrence of knee joint injuries in this athlete (p>0.05). Most injuries are caused through seoi nage and uchi mata, what is probably caused by the popularity of these techniques. With regard to the number of athletes using a throw as special technique tai otoshi seems to be the most knee joint endangering technique. Uchi mata is the technique causing most anterior cruciate ligament ruptures (p<0.05). Bruises of the knee joint appear most often in seoi nage situations (p<0.05).
Conclusion: A judoka with an affinity to knee joint injuries is supposed to specialize on hip throwing techniques. This athlete should probably avoid specializing on tai otoshi or uchi mata.
