– Discussion: – ultimate effects of rotation of TKR components: – internal rotation of tibial component w/ respect to tibia will cause external rotation of tibia when knee is reduced, resulting in lateral displacement of the tibial tubercle; – medial rotatation of the tibial & femoral … Read more
– Discussion: – TKR: effects of malrotation – patellar effects: – malrotation of femoral component may lead to patellofemoral dislocation or subluxation; – slight external rotation of femoral component on femur places patellofemoral groove more laterally, enhances patellofemoral stability (external rotation moves … Read more
– See: – Knee Joint Anatomy and Function: – Gait Menu: – Diagram: – Mid-Stance: – knee joint is in approx 15 deg of flexion & is moving toward extension; – primary flexors of ankle are beginning to demonstrate low grade activity; … Read more
– See: Role of Knee Joint in Gait: – Discussion: – for reason of contour of femoral & tibial condyles, flexion & extension of knee joint are not simple hinge movements that occur at the elbow joint. – flexion & extension do not occur about a fixed transverse axis of rotation but rather about a constantly changing … Read more
– Discussion – roof arc concept (Matta, et al (1986)), and was based on analysis of 204 acetabular fractures with avg 3.7 year follow up; – helps determine the amount of intact acetabular dome; – is a useful method for determining need for surgery, however, it is less … Read more
– Discussion: – available in sizes from 80 mm to 240 mm (most adults require 150 to 160 mm rings for the tibia); – rings should be large enough to allow at least 2-3 cm of space between the ring and skin (inorder to avoid pressure ulcerations); … Read more
