Curtis and Fisher surgery

Curtis and Fisher surgery are used for surgical treatment of congenital knee overextension and dislocation. Congenital knee over-extension and dislocation, according to the degree of lesions are divided into 3 levels, 1 level: congenital knee joint over-extension; 2: congenital knee joint over-extension and humerus on the femur forward sub-dislocation; Level 3: Congenital knee overextension is accompanied by a total dislocation of the tibia on the femur. Curtis and Fisher describe a surgical procedure for the treatment of congenital knee dislocation and are recommended for children between 6 and 18 months of age. Surgical procedures include anterior joint capsule release, extension of the quadriceps device, and release of adhesions within the joint capsule. Some older children may require femoral or tibial osteotomy. Treatment of diseases: congenital knee dislocation Indication Curtis and Fisher surgery are available for: 1. Non-surgical treatment is ineffective, older than 6 months. 2. Older children with moderate, severe subluxation or total dislocation. Contraindications Age is greater than 6 months. Preoperative preparation 1. Regular preoperative examination. 2. Equipped with blood 200ml. Surgical procedure 1. Incision and exposure The median incision in front of the thigh extends from the 1/3 level of the femur to the humerus. 2. The lateral release of the joint capsule Exposing the muscles in front of the thigh, and cutting the quadriceps tendon above the humerus to provide a quadrilateral tendon, which is convenient for suturing the proximal muscle after extension of the extensor muscle, and can also be formed into a Z shape. Then the anterior joint capsule is cut transversely, the inner and outer support bands are released, and the posterior collateral ligament is extended to the posterior aspect. The knee joint was flexed, the free collateral ligament was removed and moved to the posterior. 3. Quadriceps tendon release Consistent with the long axis of the femur, the quadriceps tendon with a normal appearance can cause the rectus femoris to directly pull the tibia. Suture the extended quadriceps tendon to the extended rectus femoris. 4. Close the incision A drainage strip is placed in the wound, and a full-thickness suture is used to close the skin incision. complication Knee hyperextension recurrence.
