After 16 years of very frequent use of this animated data collection of hip joint forces, an error was detected in the vector diagrams of the contact forces. The x- and y-components had been interchanged. This has now been corrected. We thank Ruchi Chande for her hint to this error!
The paper Bergmann et al.: Standardized loads acting in knee implants. PLoS One. 2014;9(1)
has been identified as one of the ten most frequently cited publications in PlosOne ! Maybe you can use theese data for your own research on the knee joint. Similar data have been published on the hip joint:

Comprehensive data samples, including synchronous joint kinetics and whole body kinematics are now available for free download. The loads acting in human joints were measured at the Charité in Berlin directly in patients by using instrumented implants. Additionally to the joint contact forces kinematic and kinetic data were synchronously captured in patients with instrumented knee and hip implants at the motion analysis lab of the Julius Wolff Institute and the Humboldt University of Berlin. For the analysis of various biomechanical issues comprehensive data sets were prepared.
The comprehensive data sets contain the following information:
- joint contact forces and moments
- whole body kinematics (marker trajectories)
- ground reaction forces
Sample data sets are now released for free download which consist of 1 walking trial from one total knee and one total hip replacement subject.
Mediolateral force distribution at the knee joint shifts across activities and is driven by tibiofemoral alignment
