fixed center joint
It is predominantly used in post-operative knee braces and is characterized by a single central pivot.
In the first 30 degrees of flexion the trajectory of the joint and those of the knee coincide.
After 30 degrees of flexion, the trajectory tends to distance the two articular heads.
