What is a semitendinosus allograft?
Semitendinosus/gracilis (STG) tendon autograft has been used effectively for restoring knee stability after anterior cruciate ligament (ACL) rupture. Though ACL reconstruction with STG autograft is an effective surgical technique for return to sports, short-term hamstring strength asymmetries exist after surgery.
What happens to the semitendinosus after ACL surgery?
It has been demonstrated that the semitendinosus tendon can regenerate after being harvested in its whole length and thickness for anterior cruciate ligament (ACL) reconstruction. Ultrasound studies and guided biopsies of the regenerated tendon have shown compatibility and resembling features of the normal tendon.
What are 3 graft options for replacing a torn ACL?
In general, there are three main graft options: a patellar tendon autograft, a hamstring autograft, and an allograft.
What is a hamstring allograft?
An allograft is an organ or tissue such as bone, cartilage, tendon or skin, taken from one person (donor) and surgically placed in another person to repair damaged tissue. ACL reconstruction hamstring allograft method is a surgical procedure to replace the torn ACL with hamstring allograft.
Are the gracilis and semitendinosus tendons grafts for isolated Medio-patellofemoral ligament reconstruction?
Introduction After the first patellar dislocation, most patients report damage of the medio-patellofemoral ligament (MPFL) and surgical reconstruction is required. The purpose of this study is to systematically review current evidence and to clarify the role of the gracilis and semitendinosus tendons as graft for isolated MPFL reconstruction.
What tendons can be used for grafts?
The graft can be harvested from several tendons, auto- versus allograft or even synthetic graft. However, the most used grafts are the gracilis or semitendinosus tendons [5, 6].
What is semitendinosus tendon used for?
Most commonly it is used in combination with the semitendinosus tendon as a hamstring graft in anterior cruciate ligament (ACL) reconstructions, but it is also frequently used in other knee reconstructive procedures as well as in shoulder, elbow, hip and ankle surgery [ 1, 2, 3, 4, 5, 6 ].
What is the best graft for MPFL reconstruction?
Therefore, the semitendinosus represents the most commonly used graft for MPFL reconstruction [59, 60]. However, interest concerning gracilis tendon grafts has recently grown [6]: despite being weaker than the semitendinosus tendon, the gracilis tendon has shown a stiffness value closer to that of the MPFL ligament [6, 61].
