Background: Angular deformities of the knee, a common problem in the early years of life are frequently encountered in paediatric orthopaedics not only because of very high incidence of these deformities but also because of major parental concern in the present highly demanding sports oriented society. The purpose of this study was to discuss the role of 8-plate hemi-epiphysiodesis to correct angular deformities of the knee joint.

Materials and methods: The study had total of 25 children with total 45 knees having varus or valgus angular deformities, of which 20 were bilateral and 5 were unilateral. All patients were symptomatic and were followed for regular intervals of 6 months to observe the change of the deformity.

Results: The mean preoperative genu valgum deformity was 19.79 degrees (ranging from 13-35 degrees) and genu varum deformity was 17.29 degrees (9-25 degrees). 91.1% of the deformed knees were corrected fully at the mean final follow up period of 27 months, neutralizing the mechanical axis and correction of the deformity.

Conclusions: 8-plate is technically simple and potent tool to correct genu valgum and varus deformities around knee in children without need for osteotomies in many children. Based on the low complication rate, patient acceptance, and the rapidity of improvement, this technique should be used as treatment of choice.
