Contemporary total knee arthroplasty (TKA) has not fully restored natural patellofemoral (P-F) mechanics across the patient population. Previous experimental simulations have been limited in their ability to create dynamic, unconstrained, muscle-driven P-F articulation while simultaneously controlling tibiofemoral (T-F) contact mechanics. The purpose of this study was develop a novel simulation and validate corresponding finite element model evaluate T-F A commercially available wear...
AbstractAbstractThe hip capsule is a ligamentous structure that contributes to stability. This article developed specimen-specific finite element models replicated internal–external (I-E) laxity for ten implanted capsules. Capsule properties were calibrated minimize root mean square error (RMSE) between model and experimental torques. RMSE across specimens was 1.02 ± 0.21 Nm I-E 0.78 0.33 1.10 0.48 during anterior posterior dislocation, respectively. the same with average 2.39 0.68 Nm....
The mechanism and boundary conditions used to drive experimental joint simulators have historically adopted standardized profiles developed from healthy, non-total knee arthroplasty (TKA) patients. purpose of this study was use implant-specific in vivo kinematics generate physiologically relevant the evaluation cadaveric knees post-TKA. Implant-specific were generated by combining fluoroscopic kinematics, musculoskeletal modeling-generated quadriceps loading, telemetric compressive loading...
Four modular Total Knee Arthroplasty (TKA) prosthesis designs (Cruciate Retaining, Anterior Slide, Tibial Post and Double Cam) based on Indian anthropometric data is considered for linear static Finite Element Analysis (FEA) in the study. von Mises stresses are studied all components of fou r different at 0°, 15°, 30°, 60° 90° flexion angles.

Fatigue performance of tibial tray in total knee arthroplasty (TKA) is critical importance terms longevity the prosthesis. Standards have been proposed by American Society for Testing and Materials (ASTM) International Organization Standardization (ISO) to ensure its long-term structural integrity. The aim current study evaluate effect modularity following testing standards, using finite element analysis. Goodman Sines criteria were used compare fatigue safety factor (FSF) four modular...
The current study, compares the mechanical performance of four modular TKA prostheses based on von Mises stress distribution in tibial insert. Three-dimensional finite element (FE) models a cruciate retaining type prosthesis and three posterior stabilized (PS) namely: anterior slide, post double cam, were developed. A compressive load 2600 N was applied to FE at flexion angles 00, 150, 300, 600 900. Von evaluated all parts compared with yield strength corresponding material. below their...
