Background: Recurrent patellar dislocation (RPD) and habitual (HPD) in flexion are frequently encountered children adolescents. Purpose: To compare the radiological features of RPD HPD Study Design: Cross-sectional study; Level evidence, 3. Methods: Imaging data were collected from patients aged 9 to 15 years who received surgical treatment for or at a single institution between June 2015 Septe...

BACKGROUND The purpose of this study was to analyze femoral shaft sagittal parameters in Chinese osteoarthritis (OA) patients undergoing total knee arthroplasty (TKA) and identify whether the parameters in the coronal plane could be predictors of those in the sagittal plane. METHODS Standard long-standing anteroposterior and femoral lateral radiographs of 50 lower limbs in 50 Chinese OA patie...

BACKGROUND High tibial osteotomy is a common procedure to treat symptomatic osteoarthritis of the medial compartment of the knee with varus alignment. This is achieved by overcorrecting the varus alignment to 2-6° of valgus. Various high tibial osteotomy techniques are currently used to this end. Common procedures are medial opening wedge and lateral closing wedge tibial osteotomies. The latera...

BACKGROUND Patellar instability can cause significant disability in both pediatric and adult patients, and it is associated with several factors including genu valgum. In this study, we describe the role of a lateral opening wedge distal femoral osteotomy (DFO) combined with lateral retinacular release in addressing genu valgum with associated patellar instability. The rationale for this approa...

No conventional technique for routine assessment of tibial torsion, the twisting of tibia around the longitudinal axis, has yet gained acceptance. Clinical measurements give approximate values only. Methods employing tropometers and other mechanical devices have mainly been used for measurement in skeletal specimens and in patients, though on a limited scale. Certain roentgenographic methods ar...

PURPOSE To compare two commonly used methods of temporary hemiepiphysiodesis (staples and figure of eight plate) in the management of coronal plane deformities of the knee in skeletally immature children. METHODS This prospective study was conducted between November 2012 and November 2015. A total of 40 patients with 67 affected knee joints, having at least 1 year of skeletal growth remaining...

Our aim was to compare the degree of patellar descent and alteration in angle of the inclination of the tibial plateau in lateral closing-wedge and medial opening-wedge high tibial osteotomy (HTO) in 51 consecutive patients with osteoarthritis of the medial compartment and varus malalignment. Patellar height was measured by the Insall-Salvati (IS) and the Blackburne-Peel (BP) ratios. The tibial...

Purpose The purpose of this study is to evaluate a surgical technique that aims to address the multi-planar deformities occurring in early onset Blount's disease. Methods Seven patients (eight lower limbs) with early onset Blount's disease were treated with a surgical technique that used an external fixator to simultaneously address all aspects of deformity. Presenting radiographic parameters...

A case is presented of a twenty-eight-year-old male with bilateral closed tibial fractures presenting with no right posterior tibial pulse, who was treated with bilateral reamed intramedullary nails. A post-operative arteriogram, to assess injury to the posterior tibial artery due to the initial insult, revealed impingement of the right anterior tibial artery by the most distal screw of the dis...

background the management of distal tibia fractures continues to remain a source of controversy and debate. objectives the aim of this study was to evaluate the various complications of minimally invasive percutaneous plate osteosynthesis (mippo) using a locking plate for closed fractures of distal tibia in a retrospective study. patients and methods twenty-five patients with distal tibial frac...
