Meniscus Injury
This video describes the anatomy of a meniscus injury.
The meniscus is a piece of fibrocartilage situated between the femur and tibia joint. It serves to provide a guide for movement, cushion the joint and send feedback to the brain about the position of the limb.
The meniscus is often injured when the foot is planted and the upper leg is rotated (as in pivoting). This causes compression and shearing force at the knee joint. The ligaments provide the mechanical restraints to limit excessive movement, but if they fail, the meniscus can become damaged.
Depending on the type, location and severity of the meniscus tear, symptom presentation may vary. Athletes may complain of pinching, clicking (painful or painless) of the joint or restrictions in movement (if the meniscus become caught between the joint). Treatment for meniscus tears can include conservative care (improving joint function) or surgery. The intervention you need to return to sport is best determined after a physical examination is completed by a health care provider.
