“…1) of the corresponding TKR of the above patient was developed using Abaqus/Explicit (Abaqus 6.12, Simulia Inc., Providence, RI) to calculate the contact mechanics. The tibial insert was modeled as a non-linear material with a modulus of elasticity of 463 MPa and a Poisson's ratio of 0.46 [1]. The tibial insert and the femoral component were meshed using linear hexahedral elements (C3D8I) and quadratic tetrahedral elements (C3D10M) respectively.…”

“…Total knee replacement (TKR) is effective to replace the damaged cartilage tissues and help the patients to restore daily activities [1]. Although the survivorship of knee implants may extend beyond two decades [2], wear debris of ultra-high molecular weight polyethylene (UHMWPE) in TKR induced aseptic loosening is still a major limitation to longevity [3][4][5][6].…”

“…However, the experimental testing is associated with substantial cost and time, as a large number of low frequency gait cycles are required [8,15], while computational wear modeling is an alternative attractive solution [1,16].…”

“…Patient-specific load/kinematics play an important role in vivo wear behavior [6,17], however, the majority of previous computational wear studies [1,15,18,19] have adopted the load/motions specified in ISO 14243 (2009) [20] as the input condition. Although some studies [21] have adopted a patient-specific kinematics, the load was not from the same patient.…”

“…The predicted in vivo knee joint forces and motions can readily be used to predict the surface wear of the TKR using the methodology already established [1]. All previous wear predictions have used fixed load/kinematics for the wear simulation of TKR, and not considered the effect of the change of kinematics/load due to tibial insert geometry variation caused by wear [30][31][32][33].…”

A novel wear prediction framework was developed by coupling a patient-specific lower extremity musculoskeletal multibody dynamics model with the finite element contact mechanics and wear model of total knee replacement. The tibiofemoral contact forces and kinematics were influenced by articular surface wear, and in turn, the variations from the knee dynamics resulted in increases in the volumetric wear of 404.41 mm 3 after 30 million cycle simulation from 380.86 mm 3 from the traditional wear prediction using fixed load/motions. The developed patient-specific wear prediction framework provided a reliable virtual platform for investigating articular surface wear of total knee replacements.

The effect of kinematics, loading and centre of rotation on the wear of an unconstrained total disc replacement have been investigated using the ISO 18192‐1 standard test as a baseline. Mean volumetric wear rate and surface morphological effects were reported. Changing the phasing of the flexions to create a low (but finite) amount of crossing path motion at the bearing surfaces resulted in a significant fall in wear volume. However, the rate of wear was still much larger than previously reported values under zero cross shear conditions. Reducing the load did not result in a significant change in wear rate. Moving the centre of rotation of the disc inferiorly did significantly increase wear rate. A phenomenon of debris re‐attachment on the UHMWPE surface was observed and hypothesised to be due to a relatively harsh tribological operating regime in which lubricant replenishment and particle migration out of the bearing contact zone were limited. © 2015 Wiley Periodicals, Inc.
