This study aims to develop a knee-brace friction damper for mid-rise timber frame buildings. First, time history seismic response analysis was conducted investigate the performance of improve four-story building. Then, static cyclic loading test on beam-column joint with/without prototype carried out verify effectiveness damper. It is found that mitigates slip behavior and increases equivalent ...

Chronic tibial subluxation is a rare and complicated problem that requires careful evaluation and planning to achieve the desired outcome and patient satisfaction. Reconstruction of catastrophic knee injury requires obtaining a balance in 2 opposing goals: stability and range of motion. Complete understanding of the impact of each of the involved ligamentous structures on knee stability and mot...

Traumatic obturator hip dislocation is rare. It accounts for 6 to 10 % of traumatic dislocations. occurs in the context violent trauma a favourable position. Classically, when impact brought anteriomedial part knee while flexion and limb abduction external rotation. The diagnosis evoked before deformation Confirmation made by imaging. We report case an unhelmeted motorcycle passenger who allege...

the knee bracing steel frame (kbf) is a new type of energy dissipating frame which enjoys exceptional ductility and lateral stiffness. rather than the beam-column joint, one end of the diagonal brace in kbf is attached to the knee element. indeed, the knee element as a hysteretic damper is designed and detailed to behave like a structural fuse by sustaining controlled inelastic deformations as ...

Patellar tendon rupture in children is especially rare. The fact that the area of traumatic rupture has wide variations makes surgical treatment difficult. We present an 11-year-old boy with acute traumatic patellar tendon rupture at the tibial tuberosity attachment without avulsion fracture. Primary end-to-end repair and reinforcement using 1.5 mm stainless steel wires as a surgical strategy w...

BACKGROUND The optimal treatment option for osteochondritis dissecans of the knee is still controversial. We report the case of a boy who developed osteochondritis dissecans in the lateral femoral condyles of his bilateral knees requiring repeat surgical procedures. There has been no literature reporting juvenile osteochondritis dissecans of bilateral knees requiring repeat surgical procedures....

BACKGROUND There are clear indications for benefits of stance control orthoses compared to locked knee ankle foot orthoses. However, stance control orthoses still have limited function compared with a sound human leg. OBJECTIVES The aim of this study was to evaluate the potential benefits of a microprocessor stance and swing control orthosis compared to stance control orthoses and locked knee...
