What is the best tendon for knee cruciate ligament reconstruction? Patients often ask what material is good for the reconstruction of cruciate ligament rupture, I will first talk about the available graft materials: 1, autologous tendon (aN cord tendon, b patellar tendon bone); 2, allograft tendon; 3, artificial ligament. Autologous tendon heals better than allograft tendon, so it is preferred. 1, autologous N rope tendon: small cut trauma, small impact on function (a little impact on sprint performance), although its healing speed is slightly slower than the autologous patellar tendon bone, but a slightly longer rehabilitation period for the general population does not have too much impact. Therefore, the autologous N cord muscle becomes the first choice among all materials. 2, autologous patellar tendon bone: the incision trauma and complications are greater than those of the N cord muscle, the scar is larger, and the possibility of remaining pain is slightly greater, but its healing is the fastest, so it is suitable for athletes who are eager to regain their athletic ability. 3. Allograft tendon: It is less traumatic because there is no additional loss of autologous tendon, but its healing and long-term effect is worse than that of autologous tendon. In multiple ligament reconstruction, if the autologous tendon is not enough, the allograft tendon is used to supplement the autologous tendon. For posterior cruciate ligament reconstruction, allograft tendon can sometimes be used because of its stronger healing ability than anterior cruciate ligament. Artificial ligaments are less traumatic and have faster functional recovery, but they are inactive, and the material will always fatigue, loosen or break. In my clinical work, autologous N cord muscle is preferred for ACL reconstruction and allograft tendon is preferred for posterior cruciate ligament reconstruction. The total cost of hospitalization with autologous tendon is about $25,000 and with allograft tendon is about $40,000.
