Partial meniscectomy is the treatment of choice for tears in the avascular portion of the
meniscus or complex tears not amenable to repair.
Torn tissue is removed, and the remaining healthy meniscal tissue is contoured to a stable, balanced peripheral rim.
Meniscus repair is recommended for tears that occur in the vascular region (red zone or red-white zone), are longer than 1 cm, involve greater than 50% of meniscal thickness, and are unstable to arthroscopic probing.
