INTRODUCTION: Correct rotational alignment of the femoral component is one of the most important factors for successful total knee arthroplasty. The rotational position of the femoral component can be determined using bony landmarks, such as the transepicondylar axis, the posterior condylar axis, or the anteroposterior (AP) axis (Whiteside’s line). Rotational alignment of the femoral component ...

Background. Mechanical relation between the foot and pelvic alignment had been studied in healthy subjects and individuals with other musculoskeletal disorders; however, in chronic ankle instability (CAI), it has not yet been determined. Objectives. To investigate the difference in pelvic torsion (PT) among individuals with CAI and uninjured subjects and correlate PT with perceived ankle insta...

BACKGROUND While a full-length standing anteroposterior radiograph of the lower extremity provides the best radiographic method for assessing limb alignment, other methods must be used intraoperatively. We have employed intraoperative fluoroscopy with use of an electrocautery cord to assess limb alignment in the supine patient. METHODS We retrospectively compared the measurements of lower lim...

ABSTRACT The longevity of total knee prostheses depends mostly on the correct alignment (frontal, sagittal and axial) of the prosthetic components, soft tissue balancing and restoring the mechanical axis of the lower limb.The use of computer-assisted navigation allows more accurate and reproducible restoration of mechanical axis and component positioning, better results in patients with extra-a...

Degrapol® and PLGA electrospun fiber fleeces were characterized with regard to fiber diameter, alignment, mechanical properties as well as scaffold porosity. The study showed that electrospinning parameters affect fiber diameter and alignment in an inverse relation: fiber diameter was increased with increased flow rate, with decrease in working distance and collector velocity, whereas fiber ali...

PURPOSE In total knee arthroplasty (TKA), it is important to restore neutral mechanical alignment. The purpose of this study was to assess whether the lower limb alignment is neutral in healthy Korean females and investigate the incidence of constitutional varus knees among them. MATERIALS AND METHODS Weight-bearing full-leg standing radiographs were obtained from 118 healthy females between ...

Hip-to-ankle radiographs have been used to evaluate lower limb alignment before and after total knee arthroplasty. However, earlier studies have inappropriately used correlation to assess the reproducibility of the radiographs. We determined the reliability of the hip-to-ankle radiograph using the Bland-Altman analysis. Two consecutive hip-to-ankle radiographs were obtained in 52 patients (52 k...
