INTRODUCTION: Defective mineralization of osteoid matrix prior to physeal closure causes rickets. Poor calcification of the cartilage matrix in the zone of provisional calcification causes flattened skull, rachitic rosary, bowed legs, coxa vara and brittle bones. The recent literature has seen an increase in the incidence of the disease in both developing and developed nations. We evaluated behaviour of lower limb deformities due to nutritional rickets in 117 patients. MATERIALS AND METHODS: A prospective study was conducted from January 2009 to December 2011 for clinical and radiological evaluation of knee deformities in nutritional rickets...

BACKGROUND: Growth modulation with implants facilitates correction of angular deformities and limb-length discrepancies (LLDs) in children. Close follow-up is necessary when using growth modulation to prevent overcorrection. We examined factors associated with late follow-up and overcorrection rates in patients with late versus timely follow-up. METHODS: This was a retrospective review of growth modulation procedures in children at 1 institution from 2000 through 2014...

BACKGROUND: Assessment of changes in anatomic alignment following guided growth traditionally utilizes full-length standing radiographs which subjects patients to larger radiation doses than does a single anteroposterior radiograph of the knee. In an effort to minimize radiation exposure, the present study sought to determine whether changes in screw divergence (SD) of the 2-hole tension band plate used for hemiepiphysiodesis reliably predicts change in alignment. METHODS: A retrospective review was conducted involving all patients with genu varum or genu valgum treated with hemiepiphysiodesis at a single institution...

Very little is known about patellofemoral pain syndrome (PPFS) among young dancers. Understanding the mechanism of the injury and implementing a preventative programme are important in order to minimize the risk of PFPS. The aim of the current study is to determine the extent to which factors such as lower extremity and back characteristics are common among dancers with PFPS. The study population included 271 dancers with PFPS and 271 non-injured dancers, aged 10-16 years. All dancers were screened for morphometric profile, dance discipline (h/week), anatomical anomalies (present/absent of scoliosis, genu valgus/varum, etc...

OBJECTIVES: It is known that the screws of the eight-plate hemiepiphysiodesis construct diverge as growth occurs through the physis. Our objective was to investigate whether there is a correlation between the amount of change of the joint orientation angle (JOA) and that of the interscrew angle (ISA) of the eight-plate hemiepiphysiodesis construct before and after correction. PATIENTS AND METHODS: After the institutional review board approval, medical charts and X-rays of all patients operated for either genu valgum or genu varum with eight-plate hemiepiphysiodesis were analyzed retrospectively...

Total knee arthroplasty (TKA) without soft tissue balance can create a balanced knee to a mechanical axis of near neutral with bone cuts, and remove osteophytes thoroughly. In this study, the authors present detailed steps for performing TKA. The attached video demonstrates the TKA procedure. The patient is a 77-year-old man who had suffered from knee pain for 12 years. Physical examination showed the Apley test to be positive and that the range of motion (ROM) decreased. An X-ray filmed at the positive lateral of the knee joint and the double lower extremity revealed a progression of degenerative osteoarthritis with genu varum...

OBJECTIVE: Using unloader knee braces with 3-point pressure in knee osteoarthritis patients is debated. The main reason is discomfort resulting in poor compliance. Studying the external knee adduction moment (EKAM) curve, gold standard in the medial knee load estimation, should be helpful to reduce this discomfort. Reducing constraint solely during the stance phase of gait (combined with an inactivation during large knee flexion) should indeed considerably improve comfort. Thus, the objective of this study was to validate both a method for measuring dynamic activity of new unloader knee braces and to highlight the biomechanical effectiveness of these orthoses...

PURPOSE: The goal of this article is to present our experience on navigation for osteotomies around the knee and especially osteotomies for coronal deformities. The first computer-assisted osteotomy was performed in March 2001 and since that time more than 1000 osteotomies have been performed in our department. METHODS: All the osteotomies were performed with the Orthopilot(®) device (B-Braun-Aesculap, Tuttlingen, Germany). The main indication was for genu varum deformities but several cases were operated for genu valgum...

BACKGROUND: Despite the popularity of tension band plating (TBP) current literature lacks clinical data concerning recurrence ("rebound") of frontal plane malalignment. This study investigated the rebound phenomenon after TBP in idiopathic genu varum/valgum deformities. We analyzed factors that may contribute to the development of rebound after removal of TBP. METHODS: Patients who had correction of idiopathic valgus or varus deformities by TBP at the distal femoral and/or proximal tibial growth plate were selected from a prospective consecutive database...

BACKGROUND: Although it is believed that genu varum increases loading on the medial knee during locomotion, the acute effect of increased loading on bone stress has not been determined. This study aimed to examine the effects of locomotion and lower extremity alignment on bone water content in middle-aged adults without knee osteoarthritis. METHODS: Five males and 5 females participated. Lower extremity alignment was defined as the angle between the midpoint of the anterior mid-thigh and the midpoint of the patellar tendon using the center of the patella as the fulcrum...

PURPOSE: Growth modulation with tension band plates (TBPs) and cannulated screws is the current mainstay of treatment for pediatric lower extremity angular deformities. Solid screws have been used as an alternative to cannulated screws to decrease the risk of screw failure, particularly in obese children. The downside of solid screws is the decrease in precision of placement. This study describes a surgical technique to insert solid TBP screws accurately. METHODS: TBP insertion starts with the same conventional steps by inserting the guidewires into the epiphysis and metaphysis, straddling the physis...

Achondroplasia is the most common skeletal dysplasia. This form of dwarfism is caused by a point mutation in the fibroblast growth factor receptor 3 (FGFR3) gene, leading to inhibition of endochondral ossification for these patients. This results in a normal trunk height but shortened limbs. The discoid meniscus may be an important associated finding to better understand the common complaints of leg pain for these patients. Although the incidence for a discoid meniscus is between 3% and 5% for the general population, it is unknown with achondroplasia...

Kyungjei Woo, Yeong Seok Lee, Won-Yung Lee, Jong Sup Shim
BACKGROUND: Percutaneous lateral hemiepiphysiodesis of the lower extremity is a simple and excellent method to correct the angular and length problems cosmetically. However, the efficacy of percutaneous lateral hemiepiphysiodesis is not well established in the literature. The purpose of this study was to evaluate the efficacy of percutaneous lateral hemiepiphysiodesis for angular corrections in adolescent idiopathic genu varum patients with proximal tibia vara and identify the factors affecting the amount of deformity correction of the lower limb in the coronal plane...

Overweight and obesity in children and adolescents is a growing problem with an increasing number of patients presenting with comorbidities to pediatricians and orthopedic surgeons. This overview summarizes the most common orthopedic problems in overweight children and obesity and highlights the treatment options in addition to weight reduction and physiotherapy leaded activation. In early infancy a persitent genu varum may be seen as a sign of Blount disease. In the school ages flat feet or persistent knock-knees has a higher incidence in overweight children...

We report an unusual case of recurrent fever, inflammatory knee pain, genu varum, persistent anemia, and high erythrocyte sedimentation rate in a 28-month-old boy as late manifestations of congenital syphilis (CS). Despite standard penicillin treatment at the end of the first month of life, it recurred later in life, more than once. In the first relapse, manifested by a likely gumma lesion, the prior penicillin treatment plus a negative venereal disease research laboratory result unduly led to exclusion of CS...
