Which graft is better patellar tendon or hamstring?

Graft failure is more frequent after hamstring than patellar tendon autograft. (Knee Surg Sports Traumatol Arthrosc, 2018). Bone-patellar tendon-bone autograft could be recommended as a superior graft to hamstring autograft for ACL reconstruction in patients with generalized joint laxity: 2- and 5-year follow-up study.

What is the best graft for ACL surgery?

The patellar tendon graft (PTG) has always been the gold standard for anterior cruciate ligament (ACL) reconstruction. Yet, most orthopedic surgeons prefer hamstring grafts for younger athletes and cadaver grafts for older patients.

How strong is patellar tendon graft?

The initial graft tensile strength of bone-patellar tendon-bone autograft is 2977 N with a stiffness of 620 N/mm. This is over 1.5 times the strength and 4 times the stiffness of the native ACL. Additionally, graft fixation should be secure enough to allow early rehabilitation with rapid incorporation of the graft.

What are the disadvantages of a hamstring tendon graft?

6, 36, 37 The disadvantages are predominantly related to the donor site and include anterior knee pain, patellar fracture, patellar tendon tendinopathy, patellar tendon rupture, increased joint stiffness, weakness of the quadriceps, and higher incidence of thigh muscle atrophy; in addition, the use of such grafts can …

What are the advantages of using the patellar tendon graft?

Patella Tendon Autograft

From a biologic standpoint, the advantage of a patellar tendon graft is that the graft bone heals to host bone in six weeks, which is faster than the 8 to 12 weeks it takes for soft tissue healing.

What percentage of ACL grafts fail?

These can occur in patients with adequate or inadequate graft function. Traumatic failure of ACL reconstructions has been estimated to occur in between 5% and 10% of cases (28).

Is ACL graft stronger than original?

Benefits. The bone portion of the graft allows it to incorporate and heal very quickly into the tunnels used for the reconstruction. It is quite strong. Biomechanical studies have shown that it is about 70% stronger than a normal ACL at the time of implantation.

Does the patellar tendon grow back?

We use the patellar tendon because it has a higher success rate than the other graft options available. It is the strongest type of graft found in the body and is just as strong as a normal ACL. The other benefit is that the tendon will grow back after taking the tissue out to create the new ACL.

How long does patella graft take to heal?

This study indicated that after approximately 6 months, in most patients, the patellar tendon recovered and other symptoms around the graft donor site, such as pain, also alleviated.

Can u live without an ACL?

Without an ACL, the knee is unlikely to support aggressive landing, cutting and pivoting. Living with a torn ACL may mean limiting participation in sports, work and activities that cause the knee to swell, give way or feel unstable. Risk of other injuries.

How long does the recovery from ACL reconstruction surgery take on average?

For most people, it takes 2-9 months to fully recover from ACL surgery. A 2016 study of 80 amateur athletes found that on average, athletes returned to their sport after eight months.
