The difference between distance A and distance B was defined as the depth of resection of the proximal tibia.
A suitable experimental animal model in sheep with drill holes of 8 mm diameter and 13 mm depth within the proximal and distal humerus and femur for testing biocompatibility issues is introduced.
The previous measurements of L1 and L2 axons were carried out at the proximal depth of the lamina while the present ones at more distal depth.
The change of the joint line at the tibial side is affected by the difference between the depth of resection at the proximal tibia and the thickness of the bearing insert.
Energy deposition was found to be uniform across the depth of the detector, negating the most proximal and distal 5-μm region, a phenomenon that may be attributed to a lack of charged particle equilibrium.
The mean depth of resection at the proximal tibia was 4.7 mm (sd 1.5, 2.0 to 9.3).
Next, the depth of resection at the proximal tibia was measured using the following method (Fig. 1): both the anatomical axis of the tibia and a line perpendicular to the anatomical axis from the lowest point of the joint line (termed 'line A') were drawn.
The test implants were inserted to a depth of 3 mm into the secondary spongiosa of the proximal tibia, that is, without primary contact with the lower cortical shell.
Once the area is numb, a sharp trocar is used to insert the cannula into the joint to an initial depth of 45 mm parallel to the tibial midline and flush with the surface of the proximal tibia.
Variables with high positive loadings on PCA Factor 1 were lengths of culmen, bill from gape, mandibular symphysis, alula, tarsus, tarsus proximal, tarsus distal, toes (pes digits), and depth of the claw of digit III.
