Final answer:
A meniscal tear is most commonly associated with damage to the medial meniscus, particularly following lateral impact on the extended knee that can lead to the 'terrible triad' of knee injuries. Arthroscopic surgery is a key treatment for such injuries.
Step-by-step explanation:
The most consistent finding with a meniscal tear is damage to the medial meniscus. This is particularly likely following a strong blow to the lateral side of the knee when it is extended. A meniscal tear often occurs in combination with other injuries, such as to the tibial collateral ligament and the anterior cruciate ligament, creating a condition known as the "terrible triad." Since the medial meniscus is anchored to the tibial collateral ligament, it is more susceptible to injury. In terms of treatment, arthroscopic surgery has revolutionized the management of knee injuries, including meniscal tears, allowing for less invasive procedures and faster recovery times.
