Features of Anatomical and Functional Changes in the Patellofemoral Joint of Patients with Gonarthrosis

Abstract

Summary. In 67-72% of patients with gonarthrosis, there is an angular deviation of the tibia towards the lesion. Prolonged functioning in such conditions is accompanied by patellofemoral arthrosis, in the development of which we found patterns during unicompartmental arthroplasty of the knee joint.
 Materials and Methods. This publication is based on the materials of a clinical and radiological examination of 106 patients with angular deviation of the tibia who were operated on using the method of unicompartmental arthroplasty.
 Conclusions. The degree of patellofemoral osteoarthritis is directly dependent on the duration of the disease and the magnitude of the angular deviation of the tibia. The most degenerative-dystrophic changes occur in the knee facet and the central facet, which are displaced in the projection of the patellofemoral joint, where cartilage degeneration, subchondral sclerosis with foci of bone destruction, pronounced marginal bone growths, and exostoses progress.
