BACKGROUND AND PURPOSE Although discomfort during walking is a common complaint in individuals with knee osteoarthritis (OA), how an acute bout of walking affects femoral cartilage remains unclear. Current literature has suggested that frontal plane knee malalignment (ie, varus and valgus) is associated with the initiation and/or progression of knee OA. However, the association between knee ali...

INTRODUCTION Valgus unloader knee braces (VUB) are designed to decrease medial compartment knee loading and are effective at improving the clinical status of patients with knee osteoarthritis (OA) [1]. Whether medial comparment unloading is a consistent result of VUB or whether other kinematic and kinetic alterations occur while the VUB is worn during gait requires further exploration. The purp...

Ergogenic aids have been used to alter joint kinematics in an attempt to minimise injury risk, yet the effectiveness of these aids may be compromised following a bout of exercise. This preliminary study aimed to measure the effect of compression garments and Kinesio Tape® on lower extremity joint alignment prior to and following an exercise bout. Eight male athletes (age = 24.1 ± 3.0 years, bod...

Total knee replacement for patients with osteoarthritis and valgus deformity remains challenging, with soft tissue balance often difficult to achieve. Most orthopedic surgeons use the medial parapatellar approach for total knee replacement. However, the lateral approach described in this case allows direct access to the pathology. The valgus deformity is corrected by using a modified lateral pa...

Distal femoral medial closing wedge osteotomy (DFMCWO) may be a valuable treatment for arthritic valgus knees in young and active adults, with the possible aim of procrastinating knee replacement. 32 valgus knees (mean age : 41.4±11.2) treated with DFMCWO were retrospectively reviewed. All the knees had a lateral compartment osteoarthritis graded I-II-III according to Kellgren Lawrence classifi...

background: this is to assess one of the rare complications after total knee replacement and to assess risk factors of failure.methods: 11 patients with varus knee and an average age of 67 years underwent tka between 2005 and 2013. all patients returned with a sudden sharp knee pain, disability to walk and significant decrease in rom about 4 to 8 weeks after surgery. radiographic examination re...

INTRODUCTION Varus and valgus malalignment of the knee increases the risk of medial and lateral osteoarthritis (OA) progression, respectively [1]. T2 relaxation time correlates with collagen content [2] and water content [3] of cartilage, as well as with the integrity [4] and arrangement [5, 6] of the collagen network. It may provide a sensitive tool to detect early degenerative changes in arti...

[Purpose] Increased femoral anteversion may occur with hip internal rotation and valgus knee alignment upon landing and is considered a risk factor for anterior cruciate ligament injury. We examined the relationship between femoral anteversion and joint motion and muscle activity of the lower extremity in terms of the risk factors for anterior cruciate ligament injury. [Subjects] Sixteen health...

We used computerized simulations with 3-dimensional models of 20 cadaver femora, calculated from computed tomographic scans, and a model of a rod measuring 200 x 5 mm to study femoral alignment accuracy for unicompartmental knee arthroplasty via minimally invasive reconstruction. The anatomical axis and insertion site were identified on each femur. A simulation of all feasible flexion-extension...
