PCL injuries are more common in which sex?

PCL injuries are more common in which sex?

• A. Females
• B. Males
• C. Equally likely
• D. Not enough data

Answer: (B)

PCL injuries show a sex pattern largely driven by exposure to high-energy trauma. They occur more often in men, because men are more frequently involved in activities and accidents that deliver a strong posterior force to the knee—like high-energy motor vehicle crashes and contact sports. The ligament itself is strong, and injury requires a substantial posterior load when the knee is flexed, so the observed male predominance reflects exposure rather than a biological predisposition. Therefore, the best answer is males. The other options don’t fit because the injury is not equally common between sexes, and ample data support a sex difference due to exposure.
