'Ectomy' means 'to cut out'. 'Meniscectomy' means to cut out the meniscus.
An arthroscopic meniscectomy is a surgical procedure to cut out part or all of the knee meniscus via keyhole surgery.
Each knee has two crescentic menisci (plural) which sit in the gap between the long bones of the knee and act as shock absorbers.
The meniscus may be injured and tear, and cause symptoms.
The surgeon may consider that the torn fragment should be removed via keyhole surgery - partial arthroscopic meniscectomy. Rarely the whole meniscus is removed - total arthroscopic meniscectomy. However these days knee surgeons do their best to preserve as much as possible of the meniscus, using meniscal repair techniques such as suturing (sewing).
