lateral meniscectomy

The meniscus itself has poor blood supply and weak repair ability. Once it is damaged, it is difficult to repair it by itself. If it is not treated in time, it can cause arthritis in the late stage. Therefore, patients diagnosed with meniscus injury, discoid meniscus, meniscus cysts should be removed early. After excision, it will be repaired by fibrous tissue to form fibrocartilage instead of meniscus function. If the treatment is correct, it generally does not affect the knee function. However, it should also be pointed out that meniscal resection is an intra-articular procedure that, if not handled properly, can cause complications and affect joint function. At the same time, the incision of this operation is small, and the meniscus is tightly embedded between the tendon, the femur, and the external malleolus. It is difficult to see all of the surgery during the operation. Only after the removal, the injury can be seen. The method of diagnosis is not appropriate. Therefore, the diagnosis must be confirmed before surgery, and timely surgical resection.

The medical history and physical examination should be detailed before surgery to confirm the diagnosis. Those with a history of severe injury should pay attention to the combined damage of the ligament. Knee arthroscopy should be performed if necessary. 2. The pre-operative church encourages patients to exercise quadriceps to overcome the quadriceps atrophy caused by the knee; it is also necessary to pay attention to early exercise after surgery. 3. Check the general condition, if there is a purulent lesion, it should be cured first. Meniscus resection is an intra-articular procedure that should be prepared for the skin. Surgical procedure The incision starts from the lower part of the humerus, curved or straight down, beyond the joint gap, extending slightly to the posterior side, reaching the leading edge of the humeral head, with a total length of about 4 to 5 cm [Fig. 1]. After cutting the skin and subcutaneous tissue, in front of the lateral collateral ligament, follow the skin incision to cut the switch capsule and enter the joint. After exploring the joint, pull the patellar tendon to the inside, separate and cut the anterior horn. The free end is clamped by a toothed hemostat, and the calf is retracted and internally rotated to expand the lateral gap. The rear part of the meniscus was separated under direct vision, the back angle was cut, and all the meniscus was taken out. After suspending blood, suture layer by layer.
