Final answer:
Yes, running or squatting can cause injury to the meniscus, especially with overuse or traumatic force. The medial meniscus is more commonly injured due to its attachment to the tibial collateral ligament, and certain activities increase the risk of a meniscal injury.
Step-by-step explanation:
True, running or squatting could cause injury to the meniscus. Engaging in activities like excessive running, particularly downhill, and sports that involve plenty of knee bending can lead to overuse injuries such as runner's knee, a condition also known as patellofemoral syndrome. Injuries to the meniscus in these cases are related to overuse and potential acute trauma.
The medial meniscus tends to be more vulnerable to injury due to its anatomical connections, and a forceful blow to the lateral knee can result in a 'terrible triad' injury to the tibial collateral ligament, medial meniscus, and anterior cruciate ligament, illustrating the potential risk to the meniscus during certain physical activities.
