Genu valgum is a common orthopaedic problem in children. The vast majority of cases are physiologic variants, which resolve normally. However, there are pathologic entities due to both focal and systemic processes in which the deformity often progresses and usually requires treatment. Differentiating between the two forms is facilitated by a thorough understanding of the natural history of the ...

The standard Plug-in-Gait (PiG) protocol used in three-dimensional gait analysis is prone to errors arising from inconsistent anatomical landmark identification and knee axis malalignment. The purpose of this study was to estimate the reliability and accuracy of a custom made lower body protocol (MA) compared with the PiG protocol. Twenty-five subjects volunteered to evaluate the intertrial rel...

Wilson's disease is most common disorder of cooper metabolism. It has varied clinical presentations. We report a 12 years old female child presenting with genu valgum progressed over 6 months. Careful examination, high index of suspicion and investigations confirmed Wilson's disease.

Objectives: Children aged 10 to 12 years often show dangerous maneuvers during landing, which include increased knee valgus, placing them at higher risk of anterior cruciate ligament (ACL) injuries. The study aimed investigate the relation trunk and hip kinematics with peak abduction angle single-leg landing among preadolescent female soccer players. Methods: Thirty-six players attended study. ...

Introduction ; A functional biomechanics garment (FBG) may help to prevent injury by improved kinematics during motion such as single leg drop landing (SLDL). The purpose of this study was investigate the effects FBG on SLDL. Method Seventeen female university basketball players participated. Characteristics were designed based weight-loaded performance human movement. average values lower limb...

Elderly people with osteoarthritis of the knee and postpartum women are at risk of insufficiency fractures of the proximal fibular or tibia. We report on an 82-year-old woman with valgus osteoarthritis of the knee who developed insufficiency fractures of the right proximal fibula and then the right proximal tibia. She underwent total knee arthroplasty using a long tibial stem and a tibial locki...

The surgical goal of primary total knee arthroplasty (TKA) is to provide a well-balanced soft-tissue envelope surrounding a well-aligned, well-fixed implant. Some knee surgeons have emphasized that a good outcome in primary TKA is more dependent on soft-tissue management than bone management. Thus, it is imperative that the surgeon is familiar with knee soft-tissue balancing techniques to addre...

BACKGROUND When landing from a jump, the production of increased intersegmental knee abduction moments and coupled valgus motions has been associated with an increased risk of suffering a noncontact anterior cruciate ligament (ACL) injury in one study. This research has led to the development of a clinic-based algorithm that utilizes measures of knee valgus motion, knee flexion range of motion,...

BACKGROUND The mechanism for noncontact anterior cruciate ligament injury is still a matter of controversy. Video analysis of injury tapes is the only method available to extract biomechanical information from actual anterior cruciate ligament injury cases. PURPOSE This article describes 3-dimensional knee joint kinematics in anterior cruciate ligament injury situations using a model-based im...

Background: A requirement for a soldier is to be able to move long distances under short time with heavy external load, creating high requirements on stability in the lower extremities. Weakness in gluteus medius muscle (Gmed) which is one of the main muscles for hip stability have been associated with several forms of injury in the lower extremities and particularly in the tibiofemoral joint. ...
