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...

We compared 74 total hip arthroplasties (THAs) carried out after previous proximal femoral osteotomy with a diagnosis-matched control group of 74 primary procedures performed during the same period. We report the perioperative results and the clinical and radiological outcome at five to ten years. We anticipated a higher rate of complications in the group with previous osteotomy, but found no s...

Background Distal femoral osteotomies (DFO) can be used to correct deformities around the knee. Although osteotomies can be fixed with either internal or external fixation techniques, the advantages of one over the other are unclear. Questions/purposes We asked whether (1) for both techniques, we could accurately correct the deformities based on our preoperative goals for mechanical axis deviat...

Osteotomy procedures around the knee can alter the biomechanical axis of the knee, thereby shifting the load from one compartment to another. This can be used to unload an arthritic painful compartment or to decrease the weight experienced by a cartilage restoration procedure. Recent clinical and biomechanical studies have emphasized the importance of correcting the weight bearing axis in a car...

PURPOSE To review the outcome of Wagner double intertrochanteric osteotomy for trochanteric overgrowth and a short femoral neck in 7 adolescents. METHODS Records of one male and 6 females aged 15 to 20 years who underwent modified Wagner osteotomy for trochanteric overgrowth and a short femoral neck by a single senior surgeon were reviewed. The diagnoses were coxa vara (n=2), developmental dy...

Salter Harris fractures of the distal femur can lead to growth disturbance with resulting leg length inequality and knee deformity. We have looked at a case series (3) of patients who presented with a distal femur flexion malunion and shortening treated with a distal femoral osteotomy and plating and a proximal femoral osteotomy with a magnetic internal lengthening nail. Does a two-level osteot...

Total hip arthroplasty (THA) in proximal femoral deformity represents a relatively uncommon challenge. Proximal femoral deformity is classified depending on the etiology and location and geometry of the deformity. Classification by etiology includes developmental processes, previous trauma, or previous surgery (osteotomy or THA). The latter, previous surgery, is the most common cause of femoral...

Femoral varus osteotomy (FVO) has been widely used in the surgical treatment of Legg-Calve-Perthes disease (LCPD). Axer in 1965 reviewed FVO as a treatment of LCPD and reported a very favorable results comparing with those observed after conservative treatment. Since then, many authors have demonstrated that it can prevent femoral head deformity and restore spherical congruity, provided that th...

When performing total hip replacement (THR) in high dislocated hips, the presence of soft-tissue contractures means that most surgeons prefer to use a femoral shortening osteotomy in order to avoid the risk of neurovascular damage. However, this technique will sacrifice femoral length and reduce the extent of any leg-length equalisation. We report our experience of 74 THRs performed between 200...
