Osteoarthrosic knees with large bone defects usually develop as varus or valgus deformities, with daily functional disabilities such as pain, instability and limping. Between March 1996 and January 2003, 19 knees of 18 patients were treated through primary total knee arthroplasty using autologous bone graft using the Sculco modified technique to correct large tibial defects. Sixteen knees were ...

BACKGROUND Late-onset tibia vara (Blount disease) can be difficult to treat because of frequent morbid obesity and associated deformities, including distal femoral varus, proximal tibial procurvatum, and distal tibial valgus, that contribute to lower extremity malalignment. We present a comprehensive approach that addresses all components of the deformity and allows restoration of the anatomic ...

INTRODUCTION Valgus knee braces are effective at decreasing pain and improving function in patients with knee osteoarthritis (OA) [1]. The braces are designed to decrease loading in the medial knee compartment but previous studies are unclear if this truly occurs. Alternatively, changes in the neuromuscular system might account for the benefits of bracing. An earlier study with a small sample d...

BACKGROUND This study was undertaken to determine whether unilateral hallux valgus progresses unilaterally and to evaluate the demographics, etiologies, and radiographic findings associated with symptomatic unilateral hallux valgus deformities. METHODS Patients treated for hallux valgus between January 2004 and December 2008 were identified, and of these, 33 patients with unilateral deformiti...

PURPOSE To evaluate minimum 5-year follow-up clinical and radiological results of total knee arthroplasty (TKA) using a posterior cruciate ligament sacrificing (PS), non-substituting Advance Medial Pivot Knee. MATERIALS AND METHODS One hundred and twenty knees in 80 patients who could be followed up for more than 5 years after TKA using the PS Advance Medial Pivot Knee were evaluated retrospe...

[Purpose] This study investigated whether the toe-spread-out exercise affects the hallux valgus angle, the cross-sectional area of the abductor hallucis muscle, and the hallux valgus angle during active abduction. [Subjects and Methods] Twenty-four subjects with hallux valgus were randomly assigned to orthosis and orthosis plus toe-spread-out exercise groups. The orthosis group wore the orthosi...

PURPOSE To determine gender differences in lower-extremity joint kinematics and kinetics between age- and skill-matched recreational athletes. METHODS Inverse dynamic solutions estimated the lower-extremity flexion-extension and varus-valgus kinematics and kinetics for 15 females and 15 males performing a 60-cm drop landing. A mixed model, repeated measures analysis of variance (gender (*) jo...

INTRODUCTION Meniscectomies result in altered knee biomechanics and increase contact forces on the operated knee joint. METHODS We assessed coronal knee alignment in relation to radiological osteoarthritis grading, clinical range of movement and patient reported outcome measures 40 years after total open meniscectomies in adolescence. Thirty eight knees (30 patients) that underwent total open...

BACKGROUND The medial ulnar collateral ligament (MUCL) is an important passive stabilizer to the valgus stresses that athletes experience during overhead throwing motion. However, the role of the flexor-pronator muscles as active stabilizers to valgus stress is not well defined in the literature. The objectives of this study were to quantify the relative contribution of the individual flexor-pr...

BACKGROUND The aim of this study is to evaluate the geometry of the distal femur and the proximal tibia in the osteoarthritic knee using 3D reconstructive CT scan imaging. METHODS 449 patients with knee osteoarthritis were treated surgically in our center with patient-specific technology total knee arthroplasty. Preoperatively, all the patients underwent a CT scan according to a standard prot...
