In ACL (anterior cruciate ligament) reconstruction surgery, the graft used to replace the torn ACL is typically harvested from one of the following sources:
1. Autograft (from the patient's own body):
This is the most common and preferred option in young and active patients.
Patellar tendon (bone-patellar tendon-bone graft):
Taken from the middle third of the patellar tendon, along with small pieces of bone from the kneecap (patella) and the shinbone (tibia).
Advantages: Strong graft, bone-to-bone healing.
Common in athletes.
Hamstring tendon (usually semitendinosus ± gracilis tendon):
Taken from the inner side of the thigh.
Less painful at the donor site, smaller incision.
Healing is slower (soft tissue to bone).
Quadriceps tendon:
Taken from the tendon above the kneecap.
Becoming more popular, especially in revision surgeries.
May include a bone plug or be soft tissue only.
2. Allograft (from a donor/cadaver):
Includes tendons like patellar, Achilles, or tibialis.
Often used in older or less active patients, or for revision surgeries.
Advantages: No harvesting pain, shorter surgery time.
Disadvantages: Slightly higher risk of graft failure in young athletes; minimal risk of disease transmission.

Choice of graft depends on:
Patient’s age and activity level.
Surgeon’s preference and experience.
Whether it’s a primary or revision surgery.
