Grahic Jump Location
Typical test setup and load-time trace for the deformable and rigid interface experiments. Either a rigid or deformable impact interface was attached to the front of the load cell.
Grahic Jump Location
Schematics depicting the gross and microscopic injury classification scheme: (1,2,3) depict sagittal sections (the plane used for histological analysis) of the patella showing the typical locations of fractures (A), horizontal (B) occult microfractures, vertical occult microfractures (C), fissures of the articular surface (D). The gross fractures were categorized as follows: patellar fractures were more specifically documented as either transverse (A1) or comminuted (A2), split femoral fractures (E), or “Salter” fractures of the tibial plateau (F).
Grahic Jump Location
Schematic representations of the anterior patella showing typical regions of contact between the impactor and knee for the rigid and deformable impact interfaces for the three flexion angles
Grahic Jump Location
Schematic representations of the retropatellar surface and the femoral condyles showing typical regions of intra-articular contact. These regions and magnitudes of contact area were similar, regardless of impact interface (see Table 1). In some cases the deformable impact interface contacted a portion of the medial femoral condyle at the higher flexion angle. This occurs because the medial condyle becomes more exposed during normal patellar tracking at higher flexion angles.
Grahic Jump Location
Gross photos of the retropatellar surface showing a transverse patellar fracture (A) showing a frank fracture (small arrow) and the faint shadow showing how the fracture plane continues under the cartilage (large arrow). A split fracture of the femoral condyles is shown in (B).
