“…Mechanical lateral distal femoral angle (mLDFA) (normal range, 86° to 90°) and mechanical medial proximal tibial angle (mMPTA) (normal range, 85° to 89°) were measured on radiographs preoperatively to assess the contribution of the distal femur and proximal tibia in the origin of the knee varus deformity24). Preoperative MA and PTSA were recorded radiographically9).…”

PurposeThe purpose of this study was to document results of a less invasive technique of open wedge proximal tibial osteotomy (PTO) for the varus knee in young adults using an intramedullary tibial nail.Materials and MethodsWe prospectively studied 24 knees in 16 young patients with varus knee deformity. The mean follow-up was 54 months (range, 36 to 107 months) and the mean age of patients at the time of operation was 25.8 years (range, 18 to 40 years). The open wedge PTO was performed below tibial tuberosity using a percutaneous multiple drill-hole technique. Conventional intramedullary tibial nail was used for fixation without bone graft. Radiographic evaluations were made using mechanical alignment (MA), posterior tibial slope angle, and Insall-Salvati ratio. Union time, loss of correction, implant failure, and associated complications were also investigated.ResultsThe mean MA was significantly changed from -9.7° preoperatively to 1.1° at the final follow-up (p<0.001). There was no significant change in the proximal tibial anatomy and patellar height. All patients achieved radiographic bony union at an average of 3.1 months without loss of correction. The only complication was knee pain due to nail prominence in 3 patients.ConclusionsRadiographic evaluation indicated that PTO using an intramedullary tibial nail leads to significant improvement in radiographic parameters without changes in posterior tibial slope or patellar height. We found that this technique could be a less invasive and effective alternative for correction of the varus knee in young adults.

“…The skeletal dysplasias, including achondroplasia, multiple epiphyseal dysplasia and spondyloepiphyseal dysplasia are more rare causes of lower extremity malalignment. Other rare causes of angular deformities in children include congenital longitudinal deficiency of the tibia and fibula, 3 focal fibrocartilaginous dysplasia, 4,5 and multiple hereditary exostoses. Traumatic and infectious causes include Cozen's fracture of the proximal tibial metaphysis, which can result in a temporary valgus deformity of the proximal tibia.…”

Lower extremity angular deformities in children are relatively common problems encountered by pediatric orthopaedic surgeons. When pathologic, multiple treatment options are available for both skeletally immature and mature patients. This article reviewed and synthesized recent advances in the treatment of lower extremity angular deformities in children. Age-related normative data for the evolution of the mechanical axis of the lower extremity has recently been published for pediatric patients. Although no recent randomized controlled trials concerning angular deformity correction are available, there are a significant number of recent case series using different methods with good results.

“…1 It is now believed that many other deformities accompanied tibial varus in this disease. 2,3 Proximal tibial procurvatum and internal torsion are among the other common deformities found in Blount disease. 2 Compensatory valgus deformity of the femur, once considered common in Blount disease, has been proven vice versa.…”

“…2 Compensatory valgus deformity of the femur, once considered common in Blount disease, has been proven vice versa. 3 Adding to the contradiction, distal femoral varus takes portion in causing genu varum in late onset-disease. 3 In line with the understanding of the deformities, managements of those deformities have also advanced.…”

“…3 Adding to the contradiction, distal femoral varus takes portion in causing genu varum in late onset-disease. 3 In line with the understanding of the deformities, managements of those deformities have also advanced. If the deformities are overlooked in the management of the disease, they will lead to residual and iatrogenic translational deformities, increase the incidence of ''recurrence'', and complicate the revision surgery.…”
