How to effectively treat habitual dislocation

Habitual dislocation can easily occur in some children and women. If you want to treat it effectively, you must pay attention to the correct method. The younger the age, the better the treatment effect. You can adopt a surgical method such as partial tightening suture.

1. For the treatment of habitual patellar dislocation, the younger the age, the better the effect. It not only solves the problem of dislocation, but also avoids secondary deformities. If treatment is delayed, deformities such as secondary flexion of the hip and knee joints and increased lumbar lordosis may occur. Even knee osteoarthritis can affect work and life.

2. Tightening and suture of the medial knee fascia, joint capsule, and expanded quadriceps femoris. Myometrial transposition (Campbell), medial myometrial and muscle pedicle transposition (Krougius). Tendon transfer surgery transfers the medial hamstring muscle and strengthens the medial side of the hamstring muscle. For surgery on the lower end of the femur, supracondylar osteotomy and lateral femoral condyle elevation (Albee) were performed for patients with internal rotation of the lower end of the femur, genu varum, and dysplasia of the lateral femoral condyle. Patellar ligament transposition (Houser) Hemipatellar ligament transposition (Goldthwait) is performed in children.

Meng Jimao pointed out that habitual patellar dislocation and local structural deformities are different and cannot be solved by a single surgery. Comprehensive surgical treatment should be adopted according to different deformities. It is also recommended to use the vastus medialis muscle shift to strengthen the medial pulling force. The surgical method is to release the contracted soft tissue on the outside of the knee joint. The medial knee joint is tightened and the vastus medialis insertion is moved to the lateral side of the patella. Houser's surgery or Goldthwait's surgery is performed according to the specific situation.

3. The main symptom of habitual patellar dislocation is that when the patient flexes his knee, the patella leaves the center position of the femoral intercondylar fossa and slides to the front of the lateral femoral condyle, located on the outside of the knee joint. It not only affects the appearance of the knee, but also greatly weakens the strength of the knee joint, affecting its normal function. Over time, it will induce osteoarthritis of the knee joint. The injured area is obviously swollen, the patella is tender, the movement is obviously limited, the knee feels weak, and walking is difficult. It can be repositioned by extending the knee and gently pushing with the hands. Arthroscopy and X-ray examination showed patellar dislocation.
