Joint Loading & Musculoskeletal Analysis

The loads acting in joint prostheses and other orthopaedic implants is still partially unknown. The acting loads are required for different purposes.

Loading of hip endoprostheses

Measurement of forces and moments in the hip joint

A load profile of average and maximum joint loads during frequently occurring activities is created on the basis of measurements on ten persons. It is also investigated whether unstable walking can lead to extremely high loads. This will allow more realistic mechanical tests and improved anchoring techniques for new hip implants than before. Patients with arthrosis, fractures that are not yet fully loadable and freshly implanted, cementless implants can be given indications of highly load-bearing and therefore avoidable activities. The effectiveness of orthopaedic aids and physiotherapeutic concepts can be tested. The measurement of friction in the joint, which is possible for the first time, enables more realistic wear investigations and an improvement in the wear behaviour of the implants. With the help of synchronous joint loads and movement data, computer simulations can be improved so that the loads of all structures in the leg skeleton can be calculated with good accuracy.

The loads and associated transaction data are processed so that they are generally accessible in the database OrthoLoad.com. This will allow many other research groups to use the in vivo accurately measured data as "gold standard" for their own research questions.
