Dislocation of the Knee-joint: The knee-joint is formed by the thigh-bone above, and the large bone on the inner side of the leg called the tibia, below ; there is, in addition, at the front of the joint, the small bone called the patella or knee-pan. By dislocation of the knee...
The invention relates to a joint implant, in particular the knee joint comprising a femoral part, the insert and tibial parts. The femoral portion of the knee joint is formed by a shell (1) is connectable to a distal portion of the femur (2), p ricem as the reference surfaces that ...
knee, hinge joint that is formed by the meeting of the thigh bone (femur) and the larger bone (tibia) of the lower leg. The knee is the largest joint in the body and has to sustain the greatest stresses, since it supports the entire weight of the body above it. The rounded ends, ...
A polyethylene insert is attached to the metal tibial component. The insert will support the body's weight and allow the femur to glide across the tibia. 将聚乙烯垫片装到金属胫骨组件上。垫片能承受身体的重量,并有利于股...
The meniscus is a thickened cartilage pad between the two joints formed by the femur and tibia. The meniscus acts as a smooth surface for the joint to move on. The knee joint is surrounded by fluid-filled sacs called bursae, which serve as gliding surfaces that reduce friction of the tendo...
a.The joint between the thigh and the lower leg, formed by the articulation of the femur and the tibia and covered anteriorly by the patella. b.The region of the leg that encloses and supports this joint. 2.An analogous joint or part of a leg of a quadruped vertebrate. ...
The patellofemoral joint is the joint formed by the patella and femur (thigh bone). When you bend your knee, your patella slides through a groove in your femur called the femoral trochlea. If the patella does not slide properly on top of the f...
that terminal side and the screw in the artificial knee joint of the tibia which possesses the fixed element 12 which stops in the said tibia platform 11, the said fixed element front form is formed by the shield 12 of U form, C form and V form, the height H is smaller than width ...
This offset permits the patella to move from the top downwards and in an arcuate manner laterally inwards on the sliding surface formed by the front surface of the bridge and the front surface (13a) of the skids and resembling the anatomy of the natural joint. <IMAGE> 展开 ...
An artificial knee joint, which makes a drag (a contact stress) acting on a sliding surface upon bending small so as to evade an extraordinary abrasion and damage of a sliding surface of a tibia component and which prevents an bending angle from being decreased by preventing lifting of a fem...
