Autograft (your own tissue graft)
Quick answer
An autograft is tissue taken from your own body, most often a tendon from the same knee, and moved to replace a torn ligament such as the ACL. Doha knee surgeon Dr. Pablo Gelber at Aman Hospital explains that it heals as living tissue and carries no risk of rejection.
What it is
In ligament reconstruction the torn ligament is usually not stitched back but replaced. An autograft is a replacement taken from the patient. The three common options around the knee are the hamstring tendons, the patellar tendon with a small block of bone at each end, and the quadriceps tendon.
Over many months the graft is gradually remodelled by the body into tissue that behaves like a ligament, a process often called ligamentisation.
Why it matters for patients
Autografts are widely used for primary ACL reconstruction, particularly in young and active patients, because they incorporate reliably and have lower re-tear rates than donor tissue in that group. There is no disease transmission or rejection risk.
The trade-off is the harvest site. Taking a tendon can cause temporary soreness, numbness near the scar or weakness of that muscle group, which rehabilitation works to restore.
How the graft is chosen
The surgeon considers your age, sport, previous surgery, the shape of your knee and any work or prayer demands such as kneeling. A footballer, a padel player and someone having revision surgery may each be offered a different graft. The decision is made together after examination.
Frequently asked questions
Does losing a tendon weaken my leg permanently?
In most patients strength recovers well with rehabilitation. Some hamstring tendons partly regenerate, and the remaining muscles compensate, although small differences can persist on detailed testing.
Is an autograft stronger than the original ligament?
At surgery many grafts are as strong or stronger than the native ACL, but they weaken as they remodel in the first months, which is why rehabilitation is staged and return to sport is delayed.
