“…The calculated contact pressure was compared with previous studies on contact pressure in knee replacements [27][28][29][30]. The authors of these studies stated that the maximum contact pressure for the medial condyle could reach up to 25 MPa (Figure 10).…”

Analysis of Friction in Total Knee Prosthesis during a Standard Gait Cycle

Total knee arthroplasty is on the rise worldwide. Despite its success, revision surgeries are also increasing. According to the American Joint Replacement Registry 2020, 3.3% of revision surgeries are due to wear, and 24.2% are due to mechanical loosening. The combination of shear stresses and wear particles occurring at the bone/implant interface can lead to local osteolysis. Although the shear stresses are partially driven by joint friction, relatively little is known about the evolution of the coefficient of friction (CoF) during a gait cycle in total knee replacement. Here we describe the CoF during a gait cycle and investigate its association with kinematics (slide–roll-ratio), applied load, and relative velocity. The artificial knee was simulated by cobalt–chromium condyle on a flat ultra-high-molecular-weight polyethylene (UHMWPE) tibial plateau, lubricated by either water or proteinaceous solution. We found that the CoF is not a constant but fluctuates between the values close to 0 and 0.15. Cross-correlation suggested that this is primarily an effect of the slide–roll ratio and the contact pressure. There was no difference in the CoF between water and proteinaceous solution. Knowledge about the CoF behavior during a gait cycle will help to increase the accuracy of future computational models of total knee replacement.

“…The above relationship is correct for σ ≥ 1.1 MPa and below this pressure, the coefficient of friction increases with increasing the contact pressure. Recently, several empirical friction models for tibiofemoral joints were developed by a research group in Mexico [28,29]. Montes-Seguedo et al [30] proposed a power-law model from which the friction coefficient can be estimated in both mixed lubrication regime and full-film lubrication regime as a function of the maximum pressure (σ max ), entrainment velocity (v m ) in mm/s, and sliding-to-rolling ratio (SRR), which is written as follows.…”

“…The latter is computed as the summation of the anterior-posterior linear velocity and the multiplication of the radial distance from the tibial axis to the bottom of the tibial plateau and the internal-external angular velocity. For further information on how to determine these velocity terms, the reader is referred to the reference [28]. At this stage, a short description of the joint kinematic is presented to determine the velocity of master nodes, including their tangential speed.…”

“…Fisher and Dowson reported that the friction coefficient in artificial human joints is in the range of 0.03-0.10 [33]. However, other studies obtained higher ranges of the friction coefficient for artificial human joints, for example, 0.05-0.33 [27], 0.06-0.25 [26], and 0.06-0.17 [28,29]. Focusing on the dynamic modeling of total knee arthroplasty (TKA), some investigations have aimed at developing anatomy-based dynamic models to consider the kinetic and kinematic behavior of TKAs like quasi-static models [34][35][36][37][38][39][40][41], 2D dynamic approaches [42][43][44][45][46][47][48], and sophisticated 3D mathematical dynamic solutions [49][50][51].…”

“…In 2017, Barcenas-Sanchez et al, used a ball-on-disc test setup to obtain the friction coefficient of total knee arthroplasty during a walking gait cycle. Subsequently, they proposed a regression model to represent experimental data mathematically [28]. In 2018, Garcia-Garcia et al, continued their research work while conducting a series of experiments to develop prediction models of the friction coefficient between the metallic ball and UHMWPE disk lubricated with diluted bovine serum [29].…”

The effect of friction on nonlinear dynamics and vibration of total knee arthroplasties is yet to be investigated and understood. This research work aims at studying the influence of friction on nonlinear dynamics, friction-induced vibration, and damage of tibiofemoral joints. For this purpose, a spatial dynamic knee model is developed using an asymmetric nonlinear elastic model accounting for knee joint ligaments and a penalty contact model to compute normal contact stresses in the joint while contact detection is treated such that the associated computational time is reduced. Several friction models are considered and embedded in the dynamic model to estimate tangential friction forces in the knee joint. External loads and moments, due to the presence of all soft tissues, e.g., muscles and hip-joint reaction forces, applied to the femoral bone are determined using a musculoskeletal approach. In the post-processing stage, damage, i.e., wear and creep, are estimated using three wear models and an empirical creep formulation, respectively. In addition, a FFT analysis is performed to evaluate likely friction-induced vibration of tibiofemoral joints. Mesh density analysis is performed and the methodology is assessed against outcomes available in the literature. It can be concluded that friction influences not only the tribology, but also dynamics of the knee joint, and friction-induced vibration is likely to take place when the friction coefficient increases.
