THA Biomechanics

  Total Hip Arthroplasty (THA) Biomechanics Total Hip Arthroplasty (THA) Biomechanics A generic THA is modelled, meshed and loaded in a simulated monopodal stance. The construct was assumed distally fixed and proximally loaded by an acetabular joint load and an abductor force applied at the greater trochanter. Various parameters such as equivalent stresses and frontal plane mediolateral deflections were studied.

TKA Stress Distribution

Total Knee Arthroplasty (TKA) Stress Distribution Total Knee Arthroplasty (TKA) Stress distributions on UHMWPE tibial insert and metaphyseal femoral bone cuts are calculated using finite element analysis conducted on a generic TKA model (FEM-FEA). Different stress patterns are recognized, as produced by variations on the assumed loading conditions.

Total Knee Arthroplasty (TKA)

Total Knee Arthroplasty (TKA) Total Knee Arthroplasty (TKA) A generic TKA is modelled and meshed. The assembly includes a cobalt-chrome-alloy femoral component, a titanium-alloy tibial component and an UHMWPE (polyethylene) tibial insert. The 3D model is shown proximally fixed and distally loaded by a distributed vertical standing load. Additionally, two more load components are applied on the tibial metaphysis, namely: a concentrated anteroposterior shear at the popliteal region and a vertical extension-mechanism force at the insertion of the patellar tendon, proximal to the tibial tuberosity.

THA Stress Distribution

Stress distribution on a generic titanium-alloy femoral component, with cobalt-chrome-alloy head. Implant neck and femoral diaphysis stressed, due to vertically applied body-weight in a simulation of monopodal stance. Medial stresses at the calcar femoralis region are also recognized.
