Tibio-femoral loading during human gait and stair climbing.
TLDR
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.About:

TL;DR: In general, resultant contact forces during dynamic activities were lower than the ones predicted by many mathematical models, but lay in a similar range as measured in vivo by others.

Grand Challenge Competition to Predict In Vivo Knee Loads
Benjamin J. Fregly,Thor F. Besier,David Lloyd,Scott L. Delp,Scott A. Banks,Marcus G. Pandy,Darryl D. D'Lima +6 more
TL;DR: An annual “Grand Challenge Competition to Predict In Vivo Knee Loads” based on a series of comprehensive publicly available in vivo data sets for evaluating musculoskeletal model predictions of contact and muscle forces in the knee is introduced.

Musculoskeletal disorders associated with obesity: a biomechanical perspective.
TL;DR: There is a need to determine the physical consequences of continued repetitive loading of major structures of the locomotor system in the obese and to establish how obesity may interact with other factors to potentially increase the risk of musculoskeletal disease.
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.

Musculoskeletal disorders associated with obesity: a biomechanical perspective
TL;DR: However, there is surprisingly little scientific evidence directly linking musculoskeletal injury to altered biomechanics in the obese as mentioned in this paper, and even the biomechanical effects of obesity on the locomotor system remain unknown.

Hip contact forces and gait patterns from routine activities.
Georg Bergmann,Georg Deuretzbacher,Markus O. Heller,Friedmar Graichen,Antonius Rohlmann,J Strauss,Georg N. Duda +6 more
TL;DR: 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.
Journal ArticleDOI
A physiologically based criterion of muscle force prediction in locomotion
TL;DR: The inversely-nonlinear relationship of muscle contraction force and the possible contraction duration is utilized in a method to mathematically predict individual muscle forces and shows substantial agreement with that activity pattern predicted when endurance is used as the optimization criterion.
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.

Tensile properties of the human femur-anterior cruciate ligament-tibia complex: The effects of specimen age and orientation
TL;DR: Values found when the femur- ACL-tibia complex was tested in the anatomical orientation were higher than those reported previously in the literature and provide new baseline data for the design and selection of grafts for ACL replacement in an attempt to reproduce normal knee kinematics.

Biomechanical Analysis of an Anatomic Anterior Cruciate Ligament Reconstruction
Masayoshi Yagi,Eric K. Wong,Akihiro Kanamori,Richard E. Debski,Freddie H. Fu,Savio L. C. Woo +5 more
TL;DR: Anterior tibial translation for the anatomic reconstruction was significantly closer to that of the intact knee than was the single-bundle reconstruction, indicating that Anatomic reconstruction may produce a better biomechanical outcome, especially during rotatory loads.
