Freeman-Swanson knee prosthesis

Figure 3(a) Contours of Freeman-Swanson Knee Prosthesis Tibial Component (Initial Design). 

As discussed by Walker (1989), many other types of bicondylar cruciate-sacrificing knee designs were conceived in the 1970s (Figure 7.12). The Freeman-Swanson knee prosthesis (Freeman, Swanson, and Todd 1973), developed at...

Experiments were carried out in the simulator on an early form of Freeman-Swanson Knee Joint and on a Leeds Knee Joint. Distilled water was allowed to drip onto the prosthesis to wet the interface, the flow rate being adjusted to maintain temperature of the tlbial component at 37 C. Contour diagrams based upon holography are recorded for the initial and worn tlbial components of each joint in Figures 3 and 4 and schematic representations of the wear scars are shown in Figures 5 and 6.
