OrthoLoad is a free public data base. No registration is required.
		The loads acting in orthopaedic implants during various activities are displayed in videos and are available as data files. The loads were measured directly in patients, using ‘smart’ implants. Currently studies on the loading of knee and shoulder joints, and on vertebral body replacements are under way, as well as a new hip joint study. Numerical and video data become accessible from OrthoLoad as soon as they are published in scientific journals. In the future additional information like ground reaction forces and gait data will be added. Work on the hip joint started 1988 at the Biomechanics Lab of the Oskar Helene Heim in Berlin. Much of this data is accessible. The studies are now continued at the Julius Wolff Institute of the Charité Berlin. We hope that this data collection will widely be used by patients, physiotherapists, scientists and surgeons, for teaching purposes, basic research, and to develop improved implants.
New Software: Averaging Strongly Varying Signals. Data from gait analysis and other biological signals often vary strongly between repeated measurements. A new method was developed to average such signals. A demo program and programming tools can be downloaded from menu ‘TUTORIALS’.
