“…Ardern et al found similar results for athletes from different kinds of ball sports, 61% of whom had attempted to return to their preinjury level 35. For judo athletes, it has been suggested that ACL rupture is the most serious knee injury 23. Until now, this suggestion has not been confirmed by the literature 2 19–22 36 37.…”

Moreover, there is a high risk of repeated injuries after the first lesion sustained during these shoulder throws, mostly caused by the too quick resumption of physical activity after the sustained trauma 26.…”

“…Knee sprains, which mainly affect the MCL and ACL in the judo population,47 are often caused by leg techniques, for example, O Soto Gari 38 48. Also, having a different grip style from the opponent seems to be a risk factor for ACL injuries 38. Lesions of the collateral ligament vary according to the violence of the trauma 38.…”

BackgroundThere is limited knowledge on epidemiological injury data in judo.ObjectiveTo systematically review scientific literature on the frequency and characteristics of injuries in judo.MethodsThe available literature up to June 2013 was searched for prospective as well as retrospective studies on injuries in judo. Data extraction and presentation focused on the incidence rate, injury risk, types, location and causes of injuries.ResultsDuring the Olympic Games in 2008 and 2012, an average injury risk of about 11–12% has been observed. Sprains, strains and contusions, usually of the knee, shoulder and fingers, were the most frequently reported injuries, whereas being thrown was the most common injury mechanism. Severe injuries were quite rare and usually affected the brain and spine, whereas chronic injuries typically affected the finger joints, lower back and ears. The most common types of injuries in young judo athletes were contusions/abrasions, fractures and sprains/strains. Sex-differences data on judo injuries were mostly inconsistent. Some studies suggested a relationship between nutrition, hydration and/or weight cycling and judo injuries. Also, psychological factors may increase the risk of judo injuries.ConclusionsThe present review provides the latest knowledge on the frequency and characteristics of injuries in judo. Comprehensive knowledge about the risk of injury during sport activity and related risk factors represents an essential basis to develop effective strategies for injury prevention. Thus, the introduction of an ongoing injury surveillance system in judo is of utmost importance.

“…This study of Japanese judo players found that certain stances left players exposed to kicks that could result in contact ACL ruptures [16]. This study suggests that education about risky stances and movements can be useful in reducing contact ACL injuries among judo players [15].…”

The anterior cruciate ligament (ACL), the knee ligament that runs from the posterior medial aspect of the lateral femoral condyle in the intercondylar notch to the anterior aspect of the intercondylar eminence of the tibia, limits anterior movement of the tibia relative to the femur. As such, it is the knee ligament most often ruptured by athletes. While the ACL can be ruptured due to contact injuries, it is more often ruptured due to non-contact injuries, usually when an athlete hyperextends the knees or suddenly changes direction while moving.Current studies on ACL injuries have focused on trying to explain which sports place an athlete at greatest risk for ACL injuries, or why female athletes are more likely to suffer from ACL injuries than male athletes in a given sport. However, very little research has been conducted on how the incidences, or numbers of new cases per year, of ACL injuries compare among different countries. In this review, we look at studies on ACL injuries in the general populations of select countries, and in populations of athletes of specific sports in different countries, to see how their injury incidences compare.It is estimated that in the United States of America (USA), there are 200,000 ACL injuries, half of which require reconstructive surgeries. However, currently only Norway, Denmark, and Sweden have national web-based registries that accurately record nationwide ACL reconstructions, which are presumed to reflect the incidences of ACL injuries . Denmark is the only country to mandate reporting of ACL injuries to its registry [3]. Based on reviews of these registries since their first entries, the incidences of ACL injuries were 34 per 100,000 people in Norway, 38 per 100,000 people in Denmark, and 32 per 100,000 people in Sweden.Other studies using insurance claims for ACL reconstructions have found incidences of 32 per 100,000 people in Germany based on data from the 1990s show ACL incidences between 30 and 36 per 100,000 people, which is a similar range of incidences to those seen in the Scandinavian registries during the same period of time [5]. Overall, the data from these countries and the Scandinavian ones appear to show only a small variation in ACL injury incidences of entire national populations.Although national incidences of ACL injuries from these six countries appear to fall within a range of 29 to 38 per 100,000 people, studies of athletes playing the same sport in different countries have shown very different injury incidences. This is seen even as incidences are reported using different denominators; some studies report incidences as injuries per athlete per day, while others report them as injuries per athletic exposure. An athletic exposure is defined as one athlete participating in a single game or practice session that could expose him or her to injury [6]. Although many studies were prospective and therefore were able to AbstractAnterior cruciate ligament, or ACL, injuries are among the most common athletic injuries that occur in the world. While many studi...

The common mechanisms of anterior cruciate ligament injuries in judo: a retrospective analysis

Abstract: Grip style may be associated with ACL injury occurrence in judo. In addition, direct contact due to the opponent's attack may be a common mechanism for ACL injuries in judo.
