Cruciate ligament rupture is treated with arthroscopic reconstructive surgery for most young and middle-aged patients. Depending on the skill level of the surgeon and the method of reconstruction, there is some difference in the postoperative outcome of the patient. For the surgeon, the learning curve for arthroscopic ACL reconstruction is usually longer than for general surgery. After selecting an experienced surgeon for ACL surgery, the choice of ligament reconstruction method includes: graft material and bone tract location and fixation method. Among the graft materials patients can choose, graft materials include: 1, autologous semitendinosus femoris thin tendon (autologous patella-tendon-bone gradually reduced), for a single ligament reconstruction most commonly used materials; 2, homogeneous allogeneic tendon, multiple ligament injuries are preferred; 3, artificial tendon is not commonly used in clinical practice. Autologous tendon is the safest, but the number is limited; allogeneic tendon can control the reconstruction tendon roughness, especially for multiple ligament rupture and posterior cruciate rupture application is more, there is potential rejection, infection possibility (we apply more than 10 years, no abnormal reaction is found); artificial tendon we apply rarely. The position of the reconstructed bone tract and the reconstruction method (single bundle and double bundle) are the most skillful one adopted according to the different views of the operator, but anatomical reconstruction should be performed as much as possible to restore the maximum joint function of the patient.
