Anterior cruciate ligament reconstruction
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.

Procedure
There are numerous surgical techniques for ACL reconstruction 1-3:
- autograft reconstruction
- bone-patellar tendon-bone autograft
- hamstring autograft
- four-strand autograft from semitendinosus and/or gracilis tendons
- quadriceps tendon autograft
- allograft reconstruction
- synthetic graft reconstruction
The bone-patellar tendon-bone autograft and four-strand hamstring autograft are the two most commonly employed techniques 1,2.
Complications
See article anterior cruciate ligament (ACL) reconstruction complications for further details.
Outcomes
Clinical failure is reported in ~10% (range 6-12%) of patients 4. ~17.5% (range 13.6-21.5%) of patients develop symptomatic osteoarthritis post ACL reconstruction 1.
