Total knee arthroplasty following valgus deformity is a challenging procedure due to the unique set of problems that must be addressed. The aim of this study is to determine, with a finite element analysis, the load distribution for an inclined valgus prosthetic balanced knee and to compare these results with those of a prosthetic balanced knee with an uninclined interline. Computational simula...

Objective(s): The effect of silica nanoparticles (SNPs) in sport shoes outsoles on the  parameters related to anterior cruciate ligament (ACL) Injury has not been investigated. The aim of this study was to investigate the effect of shoes outsole containing a composite of thermoplastic elastomer based on styrene-butadiene and silica nanoparticles (TPEN shoe) on Knee Valgus Angle (KVA) as a risk ...

Valgus deformity can exist during knee flexion besides extension, which could lead to patellofemoral joint instability and soft tissue imbalance in the flexion gap, and thus complicate the surgical procedures. Valgus deformity during knee flexion can be measured by radiographic analysis using long‐film radiograph and computed tomography (CT) scans.[4] It usually results from a bone defect in th...

Background Knee osteoarthritis is a debilitating condition and increased dynamic loading at the knee has been linked with increased progression of the disease. Lateral wedge insoles have been used in clinical practice since the late 1980s. It is theorised that lateral wedge insoles increase the subtalar joint valgus orientation and increase the ankle valgus moment [1], with subsequent reduced k...

The medial collateral ligament is the most commonly injured knee ligament. Valgus stress radiographs are reported to be an effective way to quantify the medial compartment opening. However, most of the techniques require the presence of a physician in the radiograph room to apply a manual valgus stress force, and can only be performed in 1 knee at a time. These techniques, although extremely ef...

We describe the mid-term results of a prospective study of total knee replacement in severe valgus knees using an osteotomy of the lateral femoral condyle and computer navigation. There were 15 knees with a mean valgus deformity of 21 degrees (17 degrees to 27 degrees) and a mean follow-up of 28 months (24 to 60). A cemented, non-constrained fixed bearing, posterior-cruciate-retaining knee pros...

Female athletes are substantially more susceptible than males to suffer acute non-contact anterior cruciate ligament injury. A limited number of studies have identified possible biomechanical risk factors that differ between genders. The effect of fatigue on the biomechanics of landing has also been inadequately investigated. The objective of the study was to examine the effect of gender and fa...

A total knee replacement is one of the most successful orthopedic procedures to enable the patient’s return to a normal, active lifestyle. The angle of the mechanical axis depends on the surgeon’s decision, which effects the strain distribution on the femoral bone and may lead to a fracture of the femur . This study evaluated the equivalent total strain on the femoral shaft under daily activiti...

OBJECTIVE Leg length discrepancy and excessive knee valgus are potential complications of juvenile chronic arthritis of the knee. The aim of the present study was to evaluate retrospectively the safety and efficacy of temporary stapling of the knee epiphyses in management of valgus deformities of the knee in children with JCA. METHODS Medical data of the patients with temporary epiphyseodesis...

OBJECTIVE Excessive frontal plane knee movement during forward lunge movements might be associated with the occurrence of knee injuries in tennis. Here, we attempt to determine whether hip muscle strength is related to the frontal plane motion of the knee during a functional lunge movement. DESIGN A correlational study. PARTICIPANTS A total of 84 healthy subjects (76 men, 8 women), with no ...
