Arthroscopic meniscectomy is a surgical keyhole procedure to remove all or part of the meniscus of the knee.

The arthroscope provides illumination and projects a camera image onto a monitor above the surgeon's head. The other hand controls the instruments to cut free the damaged part of the meniscus.


Extent of the meniscectomy

A meniscectomy may be a trimming of the meniscus, a partial meniscectomy - where only part of the meniscus is removed - or a full meniscectomy where the whole of the meniscus is removed. A key concern is the extent of resection of the important outer rim of the meniscus.


The reasons why doctors nowadays try to preserve the meniscus.

Structural and functional consequences of meniscectomy

Although a patient may feel relief after a meniscectomy, there is invariably an effect on the joint which in the longer term may lead to joint surface damage and structural changes.


Removal of the torn meniscus fragment.

An 'interpretation' of a 2008 paper looking at whether the use of a collagen meniscus is valuable after meniscus injury. The conclusion was there there was some likely benefit in patients who had had a previous meniscectomy but not in patients who had just torn their meniscus.
