Roentgenographic assessment of the biologic fixation of porous-surfaced femoral components.
Certain roentgenographic signs have value in predicting the fixation of a cementless femoral component to bone by osseointegration. Other signs have value in predicting the gross stability of aExpand

Porous-coated hip replacement. The factors governing bone ingrowth, stress shielding, and clinical results.
Total hip replacement using porous-coated cobalt-chrome femoral implants designed for biological fixation has been evaluated in 307 patients after two years and in 89 patients after five years.Expand

The influence of stem size and extent of porous coating on femoral bone resorption after primary cementless hip arthroplasty.
The influence of stem size and extent of porous coating on femoral bone resorption was examined in 411 cases of primary cementless hip arthroplasty. Moore design, cobalt alloy femoral implants withExpand

Producing and avoiding stress shielding. Laboratory and clinical observations of noncemented total hip arthroplasty.
Experimental canine model studies of stiff versus flexible, fully porous-coated, metallic femoral stems (differing by three- to fivefold in stiffness characteristics) revealed markedly differentExpand

A randomized prospective evaluation of outcomes after total hip arthroplasty using cross-linked marathon and non-cross-linked Enduron polyethylene liners.
Cross-linked liners were introduced with the promise that they would substantially reduce polyethylene wear. In 1999, our institution initiated a prospective study to compare the outcome of total hipExpand

A quantitative evaluation of periprosthetic bone-remodeling after cementless total hip arthroplasty.
Dual-energy x-ray absorptiometry analysis was used to determine the periprosthetic bone-mineral content of ten femora that had been obtained at the autopsies of five elderly patients who had had anExpand

Quantification of Implant Micromotion, Strain Shielding, and Bone Resorption With Porous‐Coated Anatomic Medullary Locking Femoral Prostheses
Fourteen femora containing porous-coated anatomic medullary locking (AML) femoral prostheses were retrieved from 12 patients at autopsy. Clinical roentgenograms in 13 femora showed bone remodelingExpand

Long-Term Results of Use of the Anatomic Medullary Locking Prosthesis in Total Hip Arthroplasty*
A total hip arthroplasty was performed, with use of the anatomic medullary locking hip system, in 223 consecutive, non-selected hips in 215 patients. The mean age of the patients at the time of theExpand

Characterization of Long-Term Femoral-Head-Penetration Rates: Association with and Prediction of Osteolysis*
Background: We examined the relationship between long-term femoral-head-penetration patterns and osteolysis in a ten-year follow-up study of a well controlled patient population. The purposes of thisExpand

Correlation between pre-operative periprosthetic bone density and post-operative bone loss in THA can be explained by strain-adaptive remodelling.
Periprosthetic adaptive bone remodelling after total hip arthroplasty can be simulated in computer models, combining bone remodelling theory with finite element analysis. Patient specificExpand
