Comparison of the clinical and radiological pictures in patients with congenital knee dislocation during treatment

Abstract

BACKGROUND: Congenital knee dislocation is a very rare musculoskeletal disease, and it occurs in approximately 1 per 100,000 live births. Many researchers note that the treatment of congenital knee dislocation should begin with conservative methods, during which various complications arise.

AIM: This study aimed to compare the clinical and radiological classifications of congenital knee dislocation and show the results of the treatment of this deformation using a Von Rosen splint and plaster corrections.

MATERIALS AND METHODS: The study included 58 patients (34 boys and 24 girls) with congenital knee dislocation (83 knee joints). Congenital knee dislocation with arthrogryposis and other systemic pathologies were not included in the study. Before treatment, all patients were assessed for the severity of congenital knee dislocation according to the Tarek and J. Leveuf system. To evaluate the obtained results, nonparametric statistics were used. To search for differences between groups, the Kruskal–Wallis test and the median test were used. To search for correlations, Spearman coefficients were used. Statistica v10 was used for statistical analysis.

RESULTS: Clinical and radiological data were compared. In both groups, after conservative treatment, excellent and good results were obtained in nearly 98% and satisfactory in 2%. After conservative therapy, surgical treatment was required in 2 of 37 knee joints with the initial severity of Tarek III deformity.

CONCLUSIONS: The severity of the deformity according to the Tarek system makes it possible to predict the effectiveness of the conservative treatment of congenital knee dislocation at a statistically significant level.
