Genu varum

Y K Lee, J W Kim, T Y Kim, Y C Ha, K H Koo
BACKGROUND: Intra-operative estimation of stem anteversion in total hip arthroplasty (THA) using postero-lateral approach is made by the surgeon's visual assessment, using the tibia as a guide, with the assumption that tibial axis is vertical to the trans-epicondylar axis. However, the accuracy of the intra-operative estimation has rarely been verified with postoperative CT-scans, with controversies regarding these measurements particularly in case of knee osteoarthritis. Therefore we performed a prospective study to: 1) determine the accuracy of the intra-operative measurement and 2) investigate factors affecting the discrepancy between the surgeon's estimation and the real stem anteversion HYPOTHESIS: Intra-operative estimation of stem anteversion correlated with the real stem anteversion on CT scan...

BACKGROUND: Children and adolescents are commonly referred to an orthopedic surgeon to assess knee malalignment. OBJECTIVES: To assess the prevalence of genu varum and valgum among adolescents, and to identify correlates of these conditions. METHODS: A medical database of 47,588 candidates for military service presenting to the northern recruitment center during an 11 year period was analyzed to identify clinical knee alignment. Based on the standing skin surface intercondylar distance (ICD) or intermalleolar distance (IMD), the prevalence rates of genu varum (ICD ≥ 3 cm) and genu valgum (IMD ≥ 4 cm) were calculated...

BACKGROUND: Since 2011, the knee service at the Nuffield Orthopaedic Centre has been offering a neutralising medial opening wedge high tibial osteotomy (HTO) to a specific group of patients with genu varum and early knee osteoarthritis. An observation was made concerning this group of patients and the presence of CAM deformity at the hip. The aim of this study is to establish whether or not any association exists between the OA phenotype shared by our HTO group and the incidence of CAM deformity at the hip...

BACKGROUND AND AIMS: The aim of this study is to evaluate the effect of proximal tibia osteotomy on hip biomechanics. METHODS: This cohort study was conducted on 50 knees of 37 patients divided into two groups of unilateral and bilateral surgeries during 2015-2016. Patients underwent medial open-wedge osteotomy of proximal tibia. Axial alignment of lower limb radiography was carried out for the patients before and after the osteotomy. RESULTS: Findings from unilateral and bilateral high tibial osteotomies demonstrated that the average of greater trochanter (GT) angle from femoral head center and also the average angle of knee varus were significantly decreased (P = 0...

Leg and foot problems in childhood are common causes of parental concern. Rotational problems include intoeing and out-toeing. Intoeing is most common in infants and young children. Intoeing is caused by metatarsus adductus, internal tibial torsion, and femoral anteversion. Out-toeing is less common than intoeing and occurs more often in older children. Out-toeing is caused by external tibial torsion and femoral retroversion. Angular problems include genu varum (bowleg) and genu valgum (knock knee). With pes planus (flatfoot), the arch of the foot is usually flexible rather than rigid...

BACKGROUND: Mutations in the COL2A1 gene cause type II collagenopathies characterized by skeletal dysplasia with a wide spectrum of phenotypic severity. Most COL2A1 mutations located in the triple-helical region, and the glycine to bulky amino acid substitutions (e.g., glycine to serine) in the Gly-X-Y repeat were identified frequently. However, the same COL2A1 mutations are associated with different phenotypes and the genotype-phenotype relationship is still poorly understood. Therefore, the studies of more patients about the recurrent mutations in COL2A1 will be needed for further research to provide more comprehensive clinical and genetic data...

When children around 2 years of age show leg bowing and diseases are ruled out based on radiographic findings without conducting blood tests, they are classified as "physiologic" genu varum. Since whether or not physiologic genu varum is associated with bone metabolism is unclear, this study was conducted to clarify the association between genu varum and bone metabolism in children. Thirty-five pediatric patients with genu varm who visited our out-patient clinic were enrolled. While two of the 35 children had nutritional rickets, showing abnormalities on both blood test (ALP, ≥1000 IU/L; iPTH, >65 pg/mL and 25(OH)D, ≤20 ng/mL) and radiographs (such as cupping, fraying or splaying), five of 35 children showed abnormalities on blood tests but not radiographs...

Partial deletion of the long arm of chromosome 7 is a rare disease and is prone to missing the diagnosis or being misdiagnosed. Here we present a case of a 13-year-old boy that showed symptoms such as growth-retardation, moderate intellectual disability, hypotelorism, microcephaly, epicanthal folds, genu varum and lumbar vertebral cleft, but it did not show serious symptoms like cleft lip, urogenital malformation and hypotonia. He was eventually diagnosed as partial deletion of the long arm of chromosome 7 syndrome through gene analysis...
