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...

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...

BACKGROUND: Total knee arthroplasty on excessive genu varum is a more demanding technique and gives worst results than procedures on moderate deformations. It remains a subject of controversies due to the lack of consensus. The purpose of our study is to evaluate the results of total knee arthroplasty (TKA) on excessive genu varum (superior to 20°) by analyzing pre and post operative clinical and radiological parameters. METHODS: We reviewed retrospectively 40 TKA in 33 patients (seven patients operated bilaterally) performed for genu varum superior to 20° between 2004 and 2011...

BACKGROUND: Accurate femoral rotational alignment is of vital importance for successful total knee arthroplasty (TKA). The value of computer-assisted surgery TKA (CAS-TKA) in increasing the accuracy of femoral rotational alignment remains controversial. We hypothesize that outcomes are related to the severity of preoperative varus and valgus deformity and that CAS-TKA may be beneficial under certain circumstances. METHODS: Between January 2007 and December 2013, patients with osteoarthritis and varus angulation in the mechanical axis (MA) ≥ 15° and valgus angulation in the MA ≥ 10° (based on hip-to-ankle standing radiography) who underwent TKA were divided into four groups...
