TLDR
The paper focuses on the loading of the femoral implant component but complete data are additionally stored on an associated compact disc that contains complete gait and hip contact force data as well as calculated muscle activities during walking and stair climbing and the frequencies of daily activities observed in hip patients.About:

Musculo-skeletal loading conditions at the hip during walking and stair climbing.
Markus O. Heller,Georg Bergmann,G. Deuretzbacher,Lutz Dürselen,M. Pohl,Lutz Claes,Norbert Haas,Georg N. Duda +7 more
TL;DR: The presented approach is considered as a useful means to determine valid conditions for the analysis of prosthesis loading, bone modeling or remodeling processes around implants and fracture stability following internal fixation.
Journal ArticleDOI
Standardized Loads Acting in Hip Implants
TL;DR: Proposals for the most demanding activities, the time courses of the contact forces and the required cycle numbers for testing are given here and it was shown that friction only very slightly influences the stresses in the implant neck and shaft.
Journal ArticleDOI
Tibio-femoral loading during human gait and stair climbing.
TL;DR: The data demonstrate that high contact and shear forces are generated during weight bearing combined with knee flexion angles greater than approximately 15° and Clinically, the conditions that produce these larger contact forces should be avoided during post‐operative rehabilitation.

Subject-Specific Finite Element Model of the Pelvis: Development, Validation and Sensitivity Studies
TL;DR: The methods developed and validated in this study will be useful for creating and analyzing patient-specific FE models to better understand the biomechanics of the pelvis.
Journal ArticleDOI
Antibiotic-impregnated cement spacers for the treatment of infection associated with total hip or knee arthroplasty.
TL;DR: Two-stage revision surgery has emerged as the standard of care for a late chronic infection at the site of a total joint replacement and the use of antibiotic-impregnated cement spacers has improved the outcomes of the treatment of infection associated with total joint arthroplasty.

Journal ArticleDOI
Hip joint loading during walking and running, measured in two patients
TL;DR: In one hip in the first patient and in the second patient the direction of large forces approximated the average anteversion of the natural femur, so the joint loading was observed over the first 30 and 18 months, respectively, following implantation.
Journal ArticleDOI
Contact pressures in the human hip joint measured in vivo
TL;DR: Data from an instrumented femoral head prosthesis implanted in apposition to natural acetabular cartilage reveal very high local and nonuniform pressures that correlate well both in magnitude and distribution with in vitro data and computer simulations of synovial joint mechanics.
Journal ArticleDOI
A biomechanical investigation of the human hip
TL;DR: The inverse dynamics problem associated with the three lower extremity segments is solved for the time variations of the intersegmental force and moment resultants at the hip, knee, and ankle.

TL;DR: The data provide information concerning the forces that must be sustained by prosthetic hip joints during a number of common activities of daily living within the first month after implantation and provide insight into the progression of early recovery.
