Abstract: Abstract-The fundamental objectives of patello-femoral joint biomechanics include the determination of its kinematics and of its dynamics, as a function of given control parameters like knee flexion or applied muscle forces. On the one hand, patellar tracking provides quantitative information about the joint's stability under given loading conditions, whereas patellar force analyses can typically indicate pathological stress distributions asso ciated for instance with abnormal tracking, The determination of th… Show more

“…The degree of medial versus lateral contact force, whether studied in vitro (Burnotte et al 1976 ;Ahmed et al 1983 ;Huberti & Hayes, 1984 ;Hayes et al 1990 ;Singerman et al 1995), inferred from cartilage thickness (Eckstein et al 1992) or estimated through finite element modelling (Heegaard et al 1995), appears to be variable within and between analyses. In general, lateral facet forces are greater than medial facet ones.…”

“…1,2 Motion of the patella relative to the femur is generally called patellar tracking or patellofemoral joint (PFJ) kinematics. Patellar maltracking results in many PFJ joint disorders, and can be associated to abnormalities at the PFJ interface and/or to lower limb malrotations.…”

“…The test subjects had no history of knee pain or trauma 3DMR imaging was performed using a 3-Tesla MR system (Intera Achieva 3.0 T Quasar Dual gradient R2.6; Philips, Best, The Netherlands) with a flex coil (Flex S_2 channel Phased Alley Coil; Philips, Best, The Netherlands) to obtain images at knee flexion angles of 120°, 90° and 60°. The limbs were examined in the lateral decubitus position, with care taken to ensure that the rotation of the tibia was not affected by the motion of the patella [20][21][22]. The MR scans were obtained by 3D WATS with a 15° flip angle, TR=20 ms, slice thickness=1.5 mm, and FOV=150 mm × 150 mm.…”

“…Therefore, studies using cadavers are being performed in order to accurately analyze the movement of the patella [19][20][21][22]. However, these studies are also limited because cadavers do not move in the same way as living subjects.…”
