Database has become fast now

The Orthoload database has now become much faster. In addition, the data selection options have become more flexible. For example, it is not only possible to select Hip Joint III data for

Activity: Walking; with Crutches; 4 Points

but also for

Activity: Walking; with Crutches (with all data for ‘4 Points’, ‘3 Points; Swing Through’ and ‘on Contralateral Side;’)


Activity: Walking (with all kinds of walking data for Hip Joint III in the database).

CAMS-Knee project online

Knowledge of the internal joint loading and movement following total knee replacement is necessary in order to understand implant stability, wear mechanisms, and loading of the surrounding soft tissue structures. In order to achieve a deeper understanding of knee joint biomechanics, the CAMS-Knee project provides synchronous data of the following measures:

TKR loading (instrumented implants, three forces and three moments)
TKR kinematics (moving fluoroscope, 3D reconstruction of tibio-femoral implant kinematics)
Whole body kinematics (marker-based movement analysis)
Ground reaction forces (force plate data)
EMG (lower limb, 16 channel)
Video (patient movement)
Multiple subjects, multiple activities, multiple repetitions



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!


Comprehensive data samples

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.


Ground Reaction Forces available

Additionally data samples of the synchronous measured Ground Reaction Forces during walking, published in “Comparison of in vivo measured loads in knee, hip and spinal implants during level walking“, are now available at the database (Additional Data – *grf2f.eof). Take a look here for further information!
