In the setting of extraarticular deformities of the knee, total knee arthroplasty (TKA) is difficult, as anatomical abnormalities obstruct identification of alignment landmarks and may preclude the use of traditional instrumentation. The long-term clinical value of computer assistance for TKA is a point of ongoing controversy. Few reports describe the use of computer-assisted orthopedic surgery...

[Purpose] From the viewpoint of prevention of knee osteoarthritis, the aim of this study was to verify how muscle strength and joint laxity are related to knee osteoarthritis. [Subjects and Methods] The study subjects consisted of 90 community-dwelling elderly people aged more than 60 years (22 males, 68 females). Femorotibial angle alignment, knee joint laxity, knee extensors and flexor muscle...

INTRODUCTION: Previous in vivo studies have not documented if ethnicity or gender influence knee kinematics for the healthy knee joint. Other measurements, such as hip-knee-ankle alignment have been previously shown to be significantly different between females and males, as well as Japanese and Caucasian populations in the young healthy knee [1]. Differences in knee kinematics in high flexion ...

We present and evaluate an automatic method to define anatomical coordinate systems (ACSs) for 3D bone models of isolated arthritic knee. The method has acceptable repeatability and can also be used for the bone shape alignment. Keywords— 3D bone model, automation, shape alignment, medical imaging, shape analysis.

Resistance training has been commonly used as a method of intervention in the rehabilitation musculoskeletal injuries affecting knee. Thus, objective this systematic review was to identify methods employed with and without implements leg press squat exercises for maintenance knee alignment. The literature search performed databases: PubMed, SciELO, Lilacs. We descriptors "muscle strength" "exer...

BACKGROUND AND PURPOSE Postoperative muscle strength and component alignment are important factors affecting functional results after total knee arthroplasty (TKA). We are not aware of any studies that have investigated the relationship between them. We therefore investigated whether coronal malalignment of the mechanical axis and/or of individual implant components would affect knee muscle str...
