Abstract

Background: Coronal deformities around the knee are most commonly presented in paediatric orthopaedic. Physiological deformities are most often managed conservatively, but severe deformities that cause pain and dysfunction require surgical intervention with acute correction (osteotomy), or gradually by hemiepiphyseodesis.
Objectives: The main objective of this prospective study is to assess and compare short term results following correction by osteotomy versus 8-plate hemiepiphyseodesis.
Patients and Methods: 30 skeletally immature patient, aged (3-14 years); presented with angular deformities, 15 patient undergone corrective osteotomy for acute correction of the deformity, 15 patients  had 8 plate hemiepiphyseodesis.
Results: The follow-up of both groups was every 3 months till 1 year post-operative. At 12-month follow-up, no statistically significant differences were observed between groups in radiographic parameters in patients with varus and valgus deformities (Independent sample t test, P > .05). At last follow-up, both groups showed statistically significant improvement in all radiographic parameters in patients with varus and valgus deformities (Repeated Measure ANOVA, P < .05).
Conclusion: This study showed no statistically significant difference in radiographic parameters between acute correction by osteotomies , and gradual correction by guided growth  at 1 year follow up.
