ACL injuries are a huge problem in judo – only 32% reaching their pre-injury level, 39% slightly reduced level, 24% quite reduced and 5% gave up judo. When I worked in professional judo, ACL repair was the most common long time injury be far, in both women and men athletes. So this is a really big issue within the sport. so knowing which techniques have a higher risk of ACL tear is super valuable information.
The incidence of ACL tears in judo is more associated with direct contact from another athlete – 70.1% vs 20.1% indirect contact. This is a lot more than others sports like basketball, soccer etc where non-contact is higher (do i have a % or something cos it seems odd to not provode something like that). It has also been discovered that it is moreso when the judoka is attacked (67.4%) Is the rest when theyre attacking? Ok later on in the article they talk about a study Della Villa et al 2020 which found 44% of ACL injuries in Italian men’s football were non contact, 44% were indirect contact and 12% were direct contact.
ok at this point im a little big confused as they start listin the results from Fushido et al I think? so would it be better to have that as the main article? Or start with Fushido and then go into this one?
In video, can talk about Osoto-gari – where depending on the technique or which mm groups are more dominant, if the attacker does hip extension with abduction – that means the (receiver Japanese word) is going to receive more of a adduction valgus. As opposed to hip extensions with ADDuction so its actually just moving more in the plane of physiological flexion extension, which obviously the knee can just absorb by bending.
Also note that more injuries happen when fighting against someone of a different stance (this is called kenka-yotsu) as opposed to the same handedness (ai-yotsu). It is speculated that the higher risk is due to the greater likelihood of being counter-attacked.
REALITY CHECK: THIS STUDY IS ACTUALLY LOOKING AT THE DIFFERENCES IN MOVEMENT PATTERNS BETWEEN GENDERS TO IDENTIFY THOSE WITH HIGHER RISK OF ACL INJURY.
They used the SL squat test. Theres some good references here for how the SLS test is a good test and assoc with ACL tears. Make a folder with these in Adobe?
This is a fantastic study from Prados-Barbero et al from Spain published in 2024.
Most common form of ACL rupture is from knee collapse into valgus in a closed-kinetic chain position.
Components of knee valgus include femoral adduction and internal rotation, knee abduction, anterior tibial translation, external tibial rotation and ankle eversion
