Surgical treatment of gonarthrosis

We observed 94 patients with gonarthrosis. Clinical observations were presented in two groups: control and main. The reasons for unsatisfactory outcomes of high corrective osteotomy of the tibia were studied based on literature data and our own material. A device for rigid fixation of bone fragments after high corrective osteotomy of the tibia has been developed and introduced into clinical practice, which allows, due to a special spacer, controlled correction of deformity and maintaining a given correction angle. The proposed device consists of a metal T-shaped locking plate with angular stability of screws and a spacer. A comparative analysis of the immediate and long-term results of surgical treatment of patients operated on using the developed device and known fixatives was carried out. In the main group, the average results were 4.7 points higher compared to the control group. The effectiveness of treatment in the main group was 17.4%, and in the control group 10.5%. The scientific research work carried out confirmed the advantages of the developed new device over traditional fixators. This is reflected in precise, controlled correction of varus deformity during surgery and stable fixation of fragments until complete consolidation. The absence of complications such as overcorrection and insufficient correction, as well as complications associated with unstable fixation
