Our experience of using a new method for surgical treatment of patellofemorals arthritis

   Introduction. Patellofemoral arthritis is a common orthopedic pathology, manifesting, as a rule, at a young, most able-bodied age. To restore the biomechanics of the patellofemoral joint and create optimal conditions for the regeneration of articular cartilage, in most cases, combined methods of surgical treatment are used. However, it should be noted that the currently used methods do not provide for the correction of all pathological changes in the patellofemoral junction, therefore further study of these problems and the development of new methods of surgical treatment are required.

   The purpose: to evaluate the clinical effectiveness of a new method of surgical treatment of patients with patellofemoral arthritis at different times in the postoperative period.

   Materials and methods. The study assessed and analyzed the results of surgical treatment of 27 patients with verified osteoarthritis of the patellofemoral joint for the period from 2020 to 2022. inclusive. The age of the patients ranged from 18 to 60 years, averaging 33 ± 1.4 years. All patients underwent surgical intervention developed by the staff of the Department of Traumatology, Orthopedics and Extreme Surgery named after Academician of the Russian Academy of Sciences A. F. Krasnova Federal State Budgetary Educational Institution of Higher Education SamSMU of the Ministry of Health of Russia a new method of surgical treatment of patellofemoral arthritis (RF patent for invention No. 2761744 dated December 13, 2021). The results of treatment of patients were assessed at 3, 6 and 12 months after surgery. Treatment results were assessed using a visual analogue pain scale, WOMAC and Kujala scales, which made it possible to assess pain, stiffness, knee joint function and quality of life of patients.

   Results. Analysis of the results of surgical treatment of patients using scales demonstrated a pronounced positive trend in mid- and late-term results. This indicates a correlation between functional restoration of the knee joint and improvement in the quality of life of patients in late follow-up after surgical treatment.

   Conclusion. The use of a new method of surgical treatment of patients with patellofemoral arthritis ensures the creation of optimal conditions for early mobilization, functional development of the knee joint and pain reduction. The proposed method of surgical treatment of patellofemoral arthritis can be recommended for use in clinical practice from the standpoint of clinical and functional restoration of the knee joint and improving the quality of life of patients.
