Objective To explore the gender difference in concomitant articular injuries after acute noncontact anterior cruciate ligament (ACL) tears. Methods The MRI data of 193 patients with clinically proved acute noncontact ACL tears was retrospectively analyzed. The subjects included 112 males and 81 females. The concomitant injuries of knee joints in the male group and female group were categorized and statistically analyzed. Results A total of 107 cases (95.5%)of bone bruises were observed among the 112 males. Thirty-two of these cases were in the medial and lateral compartments of knees (combined compartments), 70 cases in the lateral compartment, and 5 in the medial compartment. Bone bruises were observed in 72 (88.9%) of the 81 females. Sixteen cases of bone bruise were in the medial and lateral compartments of knees (combined compartments), 49 cases in the lateral compartment, and 7 in the medial compartment. There was statistically significant difference in the incidence of bone bruises in the combined compartments between the two groups (χ²=4.315, P=0.038). The incidence of medial and lateral meniscus injuries in the male group and female group was (33.9%,46.4%) and (25.9%,32.1%), respectively. The difference in the incidence of lateral meniscus injuries was statistically significant between the two groups (χ²=4.008, P=0.045). The incidence of medial and lateral collateral ligament injuries in the male and female groups was (20.5%,7.1%) and (18.5%,3.7%), respectively, so there was no statistically significant difference between the two groups. The incidence of articular cartilage injuries in male and female groups was 17.9% and 7.4%, respectively. There was statistically significant difference between the two groups (χ²=4.403, P=0.036). Conclusions Male patients with acute noncontact ACL tears are more vulnerable to concomitant bone bruises in the combined compartments, LM injuries, and articular cartilage lesions than their female counterparts.
