How is ACL graft harvested?

What is a hamstring tendon autograft?
Hamstring tendon grafts allow the surgeon to use an autograft harvested through a relatively small skin incision, resulting in minimal donor site morbidity and reduced extensor mechanism dysfunction when compared to patellar tendon autografts.
How strong is hamstring graft for ACL?
Since it has four tendon strands, the graft is very strong, up to two or three times the native ACL. Hamstring grafts have been associated with better extension, lower incidence of post-surgical arthritis and better extension strength.
How do you harvest a hamstring?
The tendon is grasped with the forceps and rolled into a clamp to prevent loosening and retraction. The tendon is grasped from the tip, and its attachment is cut. Hamstring tendon harvesting. Once the bands are released, the ST and gracilis can be identified and harvested with a tendon stripper.
Which is better autograft or allograft?
Conclusions: Autograft is superior to irradiated allograft for patients undergoing ACL reconstruction concerning knee function and laxity, but there are no significant differences between autograft and nonirradiated allograft.
What is autograft and allograft?
A patient’s own tissue – an autograft – can often be used for a surgical reconstruction procedure. Allograft tissue, taken from another person, takes longer to incorporate into the recpient’s body .

Which ACL graft is strongest?
BTB graft
The strongest option is the BTB graft. The graft incorporates more solid into the bone due to the bone plugs on either end of the tendon. However, BTB grafts have been known to have the slowest recovery time when it comes to meeting rehab milestones and returning to sport.
What is an ACL hamstring graft?
The graft used in ACL reconstruction is taken from the hamstring tendon (semitendinosus) along the inside part of the thigh and knee. Dr. Kiritsis also commonly includes a tendon just next to the semitendinousus, called the gracilis.
What is an ACL autograft?
An autograft is a part of a tendon taken from your own hamstring or knee cap that is inserted into the knee joint to replace a torn cruciate ligament. What are the advantages? An autograft is a more natural approach to ACL surgery as it uses your body’s own tissue, nearly eliminating the risk of rejection.
What happens to my hamstring tendon after ACL surgery?

What is the best graft choice for ACL reconstruction?
Patellar Tendon. The patellar tendon graft was originally described as the gold standard graft. It is still the most widely used ACL replacement graft, but is not without it’s problems. Shelbourne has pushed the envelope further with the patellar tendon graft.
Do hamstring tendons regenerate after ACL reconstruction?
Many studies have shown that the hamstring tendon will regenerate within a year after ACL reconstruction after using the hamstring tendon as an autograft. There was an excellent article that did a systematic review of the worldwide literature looking at hamstring tendon regeneration after harvesting.
What is the recovery time for hamstring surgery?
The healing time for a torn hamstring depends on where the tear occurs. If the thick middle part of the muscle is torn, recovery could take about 4 to 6 weeks.
