Anterior cruciate ligament reconstruction

Last revised by Dr Henry Knipe on 31 Aug 2021

Anterior cruciate ligament (ACL) reconstruction is a common procedure post ACL tear. It aims to reduce knee joint instability and thus prevent any further meniscal and/or cartilage damage. 

There are numerous surgical techniques for ACL reconstruction 1-3:

The bone-patellar tendon-bone autograft and four-strand hamstring autograft are the two most commonly employed techniques 1,2.

See article anterior cruciate ligament (ACL) reconstruction complications for further details.
