Computational wear prediction of artificial knee joints based on a new wear law and formulation.
TLDR
We developed a new computational wear model for knee implants, based on the contact area and an independent experimentally determined non-dimensional wear coefficient, which is capable of predicting the difference of the wear volume and wear pattern between the two kinematic inputs and the two tibial insert designs.

The effect of insert conformity and material on total knee replacement wear
The mean average life is increasing; therefore, there is a need to increase the lifetime of the prostheses. To fulfil this requirement, new prosthetic designs and materials are being introduced. TwoExpand

Comparison of the biomechanical tensile and compressive properties of decellularised and natural porcine meniscus.
Meniscal repair is widely used as a treatment for meniscus injury. However, where meniscal damage has progressed such that repair is not possible, approaches for partial meniscus replacement are nowExpand

The influence of simulator input conditions on the wear of total knee replacements: An experimental and computational study
Advancements in knee replacement design, material and sterilisation processes have provided improved clinical results. However, surface wear of the polyethylene leading to osteolysis is stillExpand

A comprehensive combined experimental and computational framework for pre-clinical wear simulation of total knee replacements
A more robust pre-clinical wear simulation framework is required in order to simulate wider and higher ranges of activities, observed in different patient populations such as younger more activeExpand

Influence of contact pressure, cross-shear and counterface material on the wear of PEEK and CFR-PEEK for orthopaedic applications
Total joint replacement is a successful surgical intervention for the treatment of the degeneration of many joints, particularly the hip and knee. As the demand for joint replacement grows, and theExpand

Quantification of the effect of cross-shear and applied nominal contact pressure on the wear of moderately cross-linked polyethylene
Polyethylene wear is a great concern in total joint replacement. It is now considered a major limiting factor to the long life of such prostheses. Cross-linking has been introduced to reduce the wearExpand

A comparison between electromechanical and pneumatic-controlled knee simulators for the investigation of wear of total knee replacements
More robust preclinical experimental wear simulation methods are required in order to simulate a wider range of activities, observed in different patient populations such as younger more activeExpand

Effect of Backside Wear and Bearing Material on Wear Performance of Rotating Platform Mobile Bearings
Introduction: Backside wear has been previously reported through in-vitro and in-vivo to have a significant contribution to the total wear in rotating bearing TKRs. The present study investigated theExpand

Representing the effect of variation in soft tissue constraints in experimental simulation of total knee replacements.
As life expectancy and activity levels of patients increase so does the demand on total knee replacements (TKRs). Abnormal mechanics and wear of TKRs can lead to implant loosening and early failure.Expand
