Labyrinthitis is inflammation of the labyrinth, a maze of fluid-filled channels in the inner ear. Vestibular neuritis is inflammation of the vestibular nerve (the nerve in the ear that sends messages related to motion and position to the brain). [2] [3] [4] Both conditions involve inflammation of the inner ear. [5]
The lateral meniscus (external semilunar fibrocartilage) is a fibrocartilaginous band that spans the lateral side of the interior of the knee joint. It is one of two menisci of the knee, the other being the medial meniscus. It is nearly circular and covers a larger portion of the articular surface than the medial.
Depending on the type and location of the tear, the patient's age, and physician's preference, injured menisci are usually either repaired or removed, in part or completely (meniscectomy). Each has its advantages and disadvantages. Many studies show the meniscus serves a purpose and therefore doctors will attempt to repair when possible.
Healing of the medial meniscus is generally not possible unless the patient is very young, usually <15 years old. Damage to the outer third of the meniscus has the best healing potential because of the blood supply, but the inner two thirds of the medial meniscus has a limited blood supply and thus limited healing ability.

A discoid meniscus is a congenital anomaly of the knee found in 3% of the population (up to 15% in Asia). It typically affects the lateral meniscus and may be found bilaterally (20%). Instead of the narrow crescent shape, as seen in a normal meniscus above, a discoid meniscus is thickened, and has a fuller crescent shape.
The sensation of pain is an unpleasant or discomforting feeling that can manifest as sensations such as pricking, tingling, burning, stinging, shooting, aching, or electric. Pain can vary in intensity, from very mild to very severe; duration, short-lived to chronic; and location, one localized area or all over the body. [4]
A person with a torn meniscus can sometimes remember a specific activity during which the injury was sustained. A tear of the meniscus commonly follows a trauma that involves rotation of the knee while it was slightly bent. These maneuvers also exacerbate the pain after the injury; for example, getting out of a car is often reported as painful.
