The aim of the study: was to improve the results of treatment in children with recurrent severe patellar dislocation, through the development of a differentiated approach to preoperative planning. Material and Methods. In SLLP Clinics Samara state medical University from 2014 to 2018 was observed 54 patients with this disease. In 37 patients recurrent severe dislocation. The average age of patients is 14.2 years. The patients underwent postural radiography of the lower extremities, radiography of the knee joint in the lateral projection, computed tomography of the knee joints, computed tomography of the hip joints. Research patients measured parameters, confirming mnohopocetny dysplastic changes of the joint angle Q, the index Insall–Salvati, the congruence angle on Merchant and anticarsia of the femoral head. Because of the severe degree of the disease, bone plastic surgery is indicated. Patients underwent corrective supracondylar derotation-dialysisa osteotomy of the femur in combination with medialization and distalization of the tibial tuberosity. During this operation, it is possible to perform a correction in all three planes. Results. In the postoperative period, 32 patients have no complications, 1 patient has relapse, 4 patients have contracture. In the long-term postoperative period 86.5% of positive results and 13.5% of unsatisfactory results, which is much lower than 36.1% — the percentage of complications according to the medical literature. Conclusion. The proposed personalized approach in preoperative planning for recurrent dislocation of the patella of severe degree, allows you to choose the best option for surgery.
