This paper explored the fracture pattern of anterior cruciate ligament (ACL) injury in Taekwondo athletes, for the purpose of improving the clinical diagnostic value of MRI. To analyze the effect of MRI diagnosis in detecting the occult fracture pattern of ACL injured knee joint, we randomly selected 1300 Taekwondo athletes with ACL injured knee fracture from a hospital, and conducted retrospective analysis of their clinical data and analyzed the distribution characteristics of their lesions. According to the results, it can be concluded that the probability for occult knee joint fracture with ACL injury was 92% (1200/1300), the probability for occult knee lateral compartment fracture with ACL injury was 85% (1100/1300). Regarding the fracture type such as lateral femoral condy- le fracture, tibia lateral frontal fracture, and lateral tibial plateau posterior fracture, the probabilities for them with ACL injuries were 80% (800/1000), 67% (600/900), and 89% (400/450), respectively. In addition, lateral tibial plateau posterior fracture, lateral femoral condyle fracture, and occult fracture of the anterior intercondylar area were all observed in combination with ACL injury. Analysis of the data showed that knee joint occult fracture was the indirect embodiment of ACL injury, with a strong association between the two. However, lateral tibial plateau posterior fracture, lateral femoral condyle “kissing contusion” and occult fracture of the anterior intercondylar area were not as associated with ACL injury.
