Purpose: We purposed to analyze the incidence and the patterns of the injuries associated with anterior cruciate ligament (ACL) tears.
Material and Methods : We retrospectively reviewed 547 knees that had undergone ACL reconstructions and compared the associated injuries according to the time of injury (acute vs. chronic), the cause of injury (sports vs. non-sports) and the type of sports.
Results: Medial collateral ligament (MCL) injury and bone contusion were more in acute injury group less than 3 months after trauma (p=0.001, 0.019) and the injuries of medial or lateral meniscus were more in chronic injury group more than 3 months after trauma (p=0.014, 0.029). The trochlea in acute injury group (p=0.027) and the medial femoral condyle in chronic injury group (p=0.011) had higher incidence of chondral injury. Grade I, II chondral injury was frequent in acute injury group (p=0.016) and grade III, IV chondral injury was frequent in chronic injury group (p=0.017). Lateral meniscus injury was frequent in sports injury group (P=0.035). Medial collateral ligament injury was frequent in ski (P=0.005), and chondral injury was in gymnastics (P=0.017).
Conclusion: The incidences of medial and lateral meniscus tears and grade III, IV chondral defects were high in chronic injury group. According to the causes of the tears and the types of sports, some differences in the incidence and pattern of associated injuries were found.
