What is a medial meniscus injury?
The medial meniscus is more prone to injury than the lateral meniscus as it is connected to the medial collateral ligament and the joint capsule and so is less mobile. Hence, any forces impacting from the outer surface of the knee, such as a rugby tackle, can severely damage the medial meniscus. In addition, medial meniscal injuries are often also associated with injuries to the anterior cruciate ligament. Other mechanisms of injury may be twisting the knee or degenerative changes that are associated with age. Any of these circumstances may lead to tearing of the medial meniscus, which in serious cases may require surgical intervention.
