Design outcomes
Primary
| Measure | Time frame |
|---|---|
| During the first post-operative time measurements will be performed once a week. During the first 6 months post-operative and after the hospital stay, measurments will be performed once a month and later on approximately every six months. | — |
Secondary
| Measure | Time frame |
|---|---|
| In the course of the study a gait analysis will be performed with the patients. For this purpose, the patients receive reflective markers taped to the skin. The movement of the markers is recorded by an an infrared camera system and allows to analyse the individual kinematic of each subject. Force plates in the floor allow the simultaneous recording of ground reaction forces. This synchronous motion and load measurment allows the validation and improvement of musculoskeletal models. | — |
