BACKGROUND Lateral compartment osteoarthritis of the knee can be a challenging pathology in the younger, active population due to limited treatment options and high patient expectations. Distal femoral osteotomy (DFO) has been reported to be a potential treatment option. PURPOSE To perform a systematic review on the survival, outcomes, and complications of DFO for treatment of genu valgum wit...

BACKGROUND Medial opening wedge high tibial osteotomy (HTO) is a well-established surgery for medial compartment knee osteoarthritis (OA) wherein the lower extremity is realigned to shift the load distribution from the medial compartment of the knee to the lateral compartment. However, this surgery is known to affect the posterior tibial slope angle (PTSA), which could lead to abnormal knee kin...

BACKGROUND Traditionally, the anatomical knee joint is locked in extension when walking with a conventional knee-ankle-foot orthosis. A powered knee-ankle-foot orthosis was developed to provide restriction of knee flexion during stance phase and active flexion and extension of the knee during swing phase of gait. OBJECTIVE The purpose of this study was to determine differences of the powered ...

Isolated lateral compartment arthritis or focal chondral defects in the setting of genu valgum young, active individuals can be treated with a varus-producing distal femoral osteotomy without cartilage treatment. Both medial closing-wedge and opening-wedge techniques have been described, neither demonstrating clear superiority. The objective this Technical Note is to describe technique biplanar...

We have used the Ilizarov technique for severe flexion deformity of the knee in 11 patients (13 knees) between 1986 and 1994 and have followed them up for an average of 4.1 years. The age of the patients at operation ranged from 1.7 to 18.8 years. The femoral and tibial components were connected by two anterior hinges, medial and lateral, and two posterior distraction rods. The deformity was co...

PURPOSE To report a new locking lateral closing wedge osteotomy used in repairing pediatric supracondylar humerus fracture malunions, which allows for coronal and sagittal plane correction of both cubitus varus and extension. METHODS At our institution, eight children with cubitus varus resulting from prior supracondylar humerus fracture malunions underwent a new technique of lateral closing ...

PURPOSE The present study investigated whether neuromuscular electrical stimulation for 20 min twice a day with an electrode placed over the soleus muscle and nutritional supplementation with 19 g of protein rich lupin seeds can reduce the loss in volume and strength of the human calf musculature during long term unloading by wearing an orthotic unloading device. METHODS Thirteen healthy male...

BACKGROUND A talus control foot orthosis (TCFO) combines an inverted rigid foot orthosis (RFO) with a broad upright portion that rises well above the navicular to cover and protect the talonavicular joint. We sought to identify the therapeutic effect of TCFOs in children with flexible flatfoot. METHODS Flexible flatfoot was diagnosed in 40 children when either of the feet had greater than 4° ...

[Purpose] The purpose of this study was to investigate the effect of restricted spinal motion on kinematic changes in the lower extremities using a rigid thoracolumbosacral orthosis. [Subjects and Methods] Forty healthy males in their 20s were selected as the sample, which was randomly and evenly divided into two groups: (1) the WT group (with a thoracolumbosacral orthosis) and (2) the WOT grou...
