If a joint space is preserved, it means the space is normal and not showing signs of Arthritis. In your case, the joint spaces in the knee were found to be normal.
The knee actually has two joints. One is called the tibiofemoral joint and is between the thigh bone (femur) and the main shin bone (tibia). The other joint is formed by the thigh bone and the knee cap (patella) and is called the patellofemoral joint. The class of joints that these form are called synovial, or freely moving joints. The specific types are: tibiofemoral joint = hinge joint and the patellofemoral joint = gliding joint.
The knee joint consists of the tibiofemoral joint and the patellofemoral joint. It is a combination of hinge and gliding joints, respectively. It is also in a class called freely movable joints, which are also called synovial, or diarthrotic joints.
The two joints are the tibiofemoral and the patellofemoral joints. The tibiofemoral joint is formed by the distal end of the femur particularly the lateral and medial femoral condyles, and the proximal end of the tibia particularly the lateral and medial tibial plateaus. Movements available at this joint are flexion & extension, internal & external rotation. The patellofemoral joint is formed by the articulation between the trochlea of the femur and the articular surfaces of the patella. Movements available at this joint are basically gliding movements that accompany tibiofemoral joint movements, namely; superior, inferior, lateral & medial gliding.
The patellofemoral joint is found in the knee, between the kneecap and thighbone.
it is not really a joint but protects the HINGE joint at tibia and femur
Patellofemoral means related to the joint between the kneecap and thighbone.
Modified hinge, condylar
pivotal hinge joint or synovial diarthrodial biaxial joint
the knee! technical name: tibiofemoral joint
the knee! technical name: tibiofemoral joint
If your referring to the knee joint it is the tibiofemoral joint.
The knee joint (tibiofemoral joint) is inferior to anything that is superior to it, and that would be the whole body above the knees.
