The correction obtained in the coronal plane knee deformity using guided growth was assessed in children with sick physes (Height<1SD of the normal children) to define the limits of this technique in sick physis We retrospectively assessed deformity correction following guided growth using 8 plates in children with coronal plane deformity and metabolically abnormal physis- renal rickets in 6 and bone dysplasias (multiple epiphyseal dyspasia, spondyloepiphyseal dysplasia, metaphyseal dysplasia, mesomelic dysplasia, chondrodysplasia punctata) in 10 children aged 2 to 14 years. Lateral distal femoral angle(LDFA) and medial proximal tibia(MPTA) angles were serially assessed after eight plate application as a day care procedure. We noted correction achieved rate of correction, complications and additional surgical procedures. Fischer's exact test and multiple regression analysis was done to assess the effect of modifiers.Purpose
