Hamstring Tendon
For this procedure, the gracilis and semitendinosus tendons from the hamstring of the injured knee are the source of the graft. A long piece (about 25 cm) is removed from each of two tendons. The tendon segments are folded and braided together to form a quadruple thickness strand for the replacement graft. The braided segment is threaded through the heads of tibia and femur and its ends fixated with screws on the opposite sides of the two bones.
Unlike the patellar tendon, the hamstring tendon's fixation to the bone can be affected by motion in the post-operative phase. Therefore, following surgery, a brace is often used to immobilize the knee for one to two weeks while the most critical healing takes place. Evidence suggests that the hamstring tendon graft does just as well, or nearly as well, as the patellar tendon graft in the long-term[citation needed].
This main surgical wound is over the upper proximal shin which would avoid the typical pain sensation when one kneel down. Besides, the wound is typically smaller than the patellar tendon graft and hence less pain after the operation. As a result, patient undergone this operation typically discharge from hospital within 2 days after surgery.
