Meniscal root tears and arthritis

Meniscus root tears may be acute, where the tear occurs suddenly and is immediately associated with incompetence of the meniscus as a shock absorber. In older people it may only be recognised when investigation of arthritis symptoms reveal a meniscal extrusion, with the meniscus slipping out over the edge of the tibia bone. Either situation may end up with the patient developing arthritis, but early recognition of an acute tear may result in referral to a specialist meniscus surgeon, and repair of the tear before arthritis is established.

Meniscal root tears are classified as Types 1-5 depending on the situation and extent of the tear.
