Background: Articular surface curvature design is important in tibiofemoral kinematics and the contact mechanics of total knee arthroplasty (TKA). Thus far, the effects of articular surface curvature have not been adequately discussed with respect to conforming, nonconforming, and medial pivot designs in patient-specific TKA. Therefore, this study evaluates the underlying relationship between the articular surface curvature geometry and the wear performance in patient-specific TKA. Methods: We compare the wear performances between conventional and patient-specific TKA under gait loading conditions using a computational simulation. Patient-specific TKAs investigated in the study are categorized into patientspecific TKA with conforming articular surfaces, medial pivot patient-specific TKA, and bio-mimetic patient-specific TKA with a patient's own tibial and femoral anatomy. The geometries of the femoral components in patient-specific TKAs are identical. Results: The anterior-posterior and internal-external kinematics change with respect to different TKA designs. Moreover, the contact pressure and area did not directly affect the wear performance. In particular, conforming patient-specific TKAs exhibit the highest volumetric wear and wear rate. The volumetric wear in a conforming patient-specific TKA is 29% greater than that in a medial pivot patient-specific TKA. Conclusion: The findings in this study highlight that conformity changes in the femoral and tibial inserts influence the wear performance in patient-specific TKA. Kinematics and contact parameters should be considered to improve wear performance in patient-specific TKA. The conformity modification in the tibiofemoral joint changes the kinematics and contact parameters, and this affects wear performance.

“…Their study showed that increasing conformity may not be the sole predictor of wear performance, and that a highly crosslinked fixed-bearing PE insert can also provide high wear performance (Flores-Hernandez, Netter, Hermida, Steklov, Kester and D. D'Lima, 2015;Netter, Hermida, D'Alessio, Kester and D'Lima, 2015). Kang et al evaluated the weight loss, wear depth, and kinematics for different surface properties, including nanostructured diamond (NSD), diamond-like carbon (DLC), titanium-nitride (TiN), and oxidized zirconium (OxZr), on femoral components in TKA using FE analysis under gait-cycle loading conditions (Kang et al, 2017c). Their study demonstrated the potential of OxZr and TiN for reducing PE wear and offers new insights into the effects of wear on TKA (Kang, Son, Kim, Baek, Kwon and Koh, 2017c).…”

Computational models have been widely used for more than four decades to evaluate the mechanical behavior of knee joint arthroplasty. Validated computational models provide a virtual platform to develop optimal articular surfaces which achieve desired implant characteristics. This review paper provides a comprehensive overview of the computational models available to represent knee joint arthroplasty. A brief overview of knee joint anatomy and arthroplasty is provided, followed by computational model development techniques. Use of the computational models in development of knee joint arthroplasty and pre-or post-clinical evaluation is summarized. This review paper presents current modeling capabilities for implant design and stability, with further suggestions for studying the performance of implants on a population level. However, simulations must include closely corroborated multi-domain analysis in order to account for real-life variability.

The wear of tibial inserts in total knee arthroplasty (TKA) remains a major limitation of longevity. However, wear tests are expensive and time-consuming. Computational wear prediction using a finite-element (FE) model followed by validation through comparison with experimental data is effective for assessing new prosthetic designs or materials prior to functional testing and surgical implementation. In this study, the kinematics, volumetric wear, and wear depth of tibial inserts made of different materials (ultrahigh-molecular weight polyethylene (UHMWPE), polyetheretherketone (PEEK), and carbon fiber-reinforced PEEK (CFR–PEEK)) in TKA were evaluated by employing FE models and analysis. The differences among the materials were evaluated using adaptive wear modeling to predict the wear depth, volumetric wear, and kinematics under a gait loading condition. The volumetric wear and wear depth of the CFR–PEEK decreased by 87.4% and 61.3%, respectively, compared with those of the UHMWPE, whereas the PEEK exhibited increased volumetric wear and wear depth. These results suggest that CFR–PEEK is a good alternative to UHMWPE as a promising and suitable material for tibial inserts used in TKA. However, orthopedic research should be performed to evaluate the threshold conditions and appropriate applications for the newly developed and introduced biomaterial.
