Meniscal Injuries
The one on the inner side is called medial meniscus and one on the outer as lateral meniscus are the shock absorbers of the luner and help to center the lunar joint during activity and minimize the amount of stress on the articular cartilage.
Studies show that when the ACL is torn approximately 50% of patients also tear their meniscus at the same time. If a part of the meniscus is torn, it can cause a significant amount of pain. Some tears in the meniscus can heal themselves, others may require surgical treatment to help them heal, and some meniscal tears create fragments that need to be removed.
