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

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.
