3D CAD conceptual design of an artificial knee.

: Total knee arthroplasty is the end-stage surgical procedure for pain relief in degenerative diseases such as arthritis. There are many models, which were designed so far in five to six decades of arthroplasty history. This research is aimed to design an artificial high-flexion knee, which emphasizes the high-flexion extension range of over 125 deg that would provide the comfort of squatting even after total knee replacement.
