The aim of the study was the analysis of domestic and foreign medical literature of different time periods, which describes the basic methods of surgical and conservative treatment of congenital or habitual dislocation of patella, as well as statistical analysis of the results of treatment. Due to the existence of a large number of options of surgical treatment for this pathology (more than 150 methods were developed) and high variability of its manifestations, it is necessary to know the basic methods and their results for planning tactics of treatment with individual approach to each patient. Based on this review, analysis was performed for the results of using different options for invasive treatment of congenital or habitual dislocation of patella. Also, the paper contains the indications and efficacy of conservative therapy for this disease. A comparative analysis was made on the results of surgical and conservative methods of treatment of patellar dislocation, which were used in different time periods, from the initial description of the first results of treatment of this pathology to modern surgical techniques that are currently used. It is shown that all methods of surgical treatment of the pathology are divided into three main groups: myofascioplastic surgeries, osteoplastic and combined surgical interventions. It is underlined that the diseases requires individual approach to the choice of correction method in each certain case to achieve positive outcomes.

In recent years, biological growth factors contained in platelet-rich plasma (PRP) obtained from the whole blood have been actively used to regenerate tissues of the musculoskeletal system. There are a lot of methods for preparing PRP, devices and modes for obtaining it, including ready-made services for use in traumatology and orthopedics. A number of well-known protocols miss important points and features of handling biological material, and fail to give clear characteristics of the resulting product. At the same time, there are a number of products that are completely opposite in composition, method, place of application and time of application, which the authors denote as PRP. In the domestic and foreign literature, several attempts have been made to characterize and classify the types of products containing plasma with platelets as a basis. In this article, we describe the existing systems used to classify PRP drugs, highlight their advantages and disadvantages. Of course, due to the active use of PRP in various fields of medicine, there remains a need for the standardized universal nomenclature for describing biological therapies, as well as for a comprehensive and reproducible classification system for products obtained from autologous blood.
