Standardized Loads Acting in Knee Implants
The loads acting in knee joints must be known for improving joint replacement, surgical procedures, physiotherapy, biomechanical computer simulations, and to advise patients with osteoarthritis or fractures about what activities to avoid. Such data would also allow verification of test standards for knee implants.
A Preliminary Biomechanical Assessment of a Polymer ...
With the resurgence of composite materials in orthopaedic applications, a rigorous assessment of stress is needed to predict any failure of bone-implant systems. For current biomechanics research, strain gage measurements are employed to experimentally validate finite element models, which then characterize stress in the bone and implant.
 CHAPTER IV FINITE ELEMENT ANALYSIS OF THE KNEE JOINT ...
CHAPTER IV FINITE ELEMENT ANALYSIS OF THE KNEE JOINT WITHOUT A MEDICAL IMPLANT 4.1 Modeling in Biomechanics The human body, apart of all its other functions is a mechanical mechanism and a structure, since it transmits movement and force. As a structure its elements may be subjected to forces and suffer stress and strain.
COMPARATIVE STRESS ANALYSIS OF LINGUALIZED AND ...
This study compares the biomechanical behavior of a mandibular full-arch fixed implant prosthesis with four implants under lingualized and conventional balanced occlusion schemes. The acrylic resin denture was supported by four titanium cylindrical implants and connected via a titanium prosthetic rectangular bar.
Comparison of Cementless and Hybrid Cemented Total Knee ...
arly condylar total knee arthroplasty (TKA) implant designs most com-monly used an all-polyethylene ce-mented tibial component.1-3 Since the mid 1980s, modular, metal-backed tibial trays have dominated the TKA implant market based on finite-element analysis studies that reported superior force distribution compared with conventional all-polyeth-...
Biomechanical investigation of the type and configuration ...
Thus, this study was to investigate the mechanical stability of HTO with locking plate and various screw fixations, including the length as well as the type. A finite element (FE) model involving a distal femur, meniscus, and a proximal tibia with HTO fixed with a titanium locking plate and screws was created.

Novel adaptive finite element algorithms to predict bone ...
These new Finite Element algorithms show that using implant materials with lower elastic modulus, osteoconductive coatings or improved implant design could lead to increased bone remodelling that optimises tissue regeneration, fulfilling the potential of enhanced porosity and complex implant designs made possible by additive layer manufacturing ......
Investigation of a Reversed Materials Early Intervention ...
A recent study of 97 arthritic knees at the time of total knee (TKA) surgery showed that 21% of the cases could have been treated with a unicompartmental knee (UKA) [1]. UKA is an attractive procedure for patients with medial compartmental osteoarthritis who wish to maintain an active lifestyle. However there is an incidence of tibial component
