Posterior Stabilized Knee Design Biomechanical Considerations, Donald E. Mcnulty
Theses
Numerous posterior stabilized knee systems are available for primary and revision total knee arthroplasty. Design of these systems requires an understanding of the articulating geometries and kinematic/kinetic biomechanical considerations of the normal knee. The findings for the normal knee are integrated into the design of a prosthetic system.
The natural femoral, tibial and patella articulating geometries are defined to enable subsequent kinematic and kinetic analyses. The articulating geometries are characterized from review of anthropometric studies of the tibiofemoral and patellofemoral joint.
The kinematic analysis of the natural knee defines knee motion in terms of rotation, adduction/abduction, range of motion and …
