Advantages and Limitations

Advantages

In patients with generalized ligamentous laxity, allografts provide better-quality collagen and a more robust and reliable graft for reconstruction.

Allograft use avoids donor-site morbidity associated with autograft harvesting from the hamstring insertion, including knee flexion strength deficit, and decreases overall surgical time.

Interference screws are widely available and less expensive than other device options for fixation of the graft in the tibia and fibula.

Adequate graft length and diameter can be verified preoperatively with the use of an allograft for reconstruction.

Limitations

Allograft use may theoretically increase the risk of infectious disease transmission if adequate screening is not performed prior to surgery.

Cost is increased with the use of a semitendinosus allograft for reconstruction in comparison to an autograft.

Allografts are not universally available, which hinders the application of this technique in certain resource-limited areas.
