Introduction
Anterior cruciate ligament (ACL) reconstruction surgery primarily involves adding a graft to replace the function of the ruptured anterior cruciate ligament. The procedure should be performed at a正规 hospital, with the following specific steps: 1) After entering the operating room, the patient lies supine on the operating table. The anesthesiologist administers local anesthesia to the knee joint, while the surgeon disinfects the patient's knee area.
Anterior cruciate ligament (ACL) reconstruction surgery primarily involves adding repair sutures to replace the function of the ruptured anterior cruciate ligament. The procedure must be performed at a正规 hospital, and the specific steps are as follows:
1. After entering the operating room, the patient lies supine on the operating table. The anesthesiologist administers local anesthesia at the knee joint, while the surgeon performs routine disinfection of the knee area and lays down sterile drapes.
2. Once the anesthesia takes effect, the surgeon makes two incisions in the knee joint—one for inserting the arthroscope and the other for the ligament reconstruction device.
3. Under arthroscopic visualization, the ruptured anterior cruciate ligament is identified. Using the ligament reconstruction device, multiple repair sutures are sewn into the distal end of the ligament. An incision is made below and to the right of the knee joint, on the lateral side of the tibia, through which a drilling guide is inserted.
4. A Kirschner wire (K-wire) is drilled from the lower right part of the tibia toward the left, with the exit point located at the ligament attachment site. A bone drill is used to create a tunnel, into which a hollow screw is inserted. The repair sutures are then passed through the hollow screw.
5. A K-wire is drilled from the lower right to the upper left direction of the femoral head. A cannulated clamp is advanced over the K-wire. All repair sutures are threaded into the clamp, which is then pulled out from within the femur.
6. The suture with an anchor is connected to the suture placed inside the tibia. The anchored suture is then pulled downward and to the right, securing the anchor onto the femoral head.
7. The repair sutures are tightened and secured with an anchor at the drilled hole in the lower right portion of the tibia.
8. Excess suture material is cut off, and all sutures and instruments are removed from the knee joint. The incisions are sutured closed, completing the surgery.
After surgery, patients should rest adequately, avoid strenuous physical activity, and maintain a light diet.
