The relatively high number of medial meniscal injuries is mainly due to the higher forces on the medial compartment of the knee joint during daily life. Higher forces on the medial compartment of the knee will result in more stress on the medial meniscus of the knee, which can lead to medial meniscus injury if the stress is more than the meniscus can withstand. There are three degrees of medial meniscus injury: I, II, and III degrees of meniscus injury, and III degrees of injury also include meniscus tears. Treatment options for the meniscus depend on the degree of meniscus damage. If the medial meniscus damage is mild, it can be treated conservatively, while more severe damage requires surgery.
