Forces during cycling after total knee arthoplasty

Recreational sport activity after total knee replacement (TKR) is of growing interest to patients. Therefore, the purpose of this study was to evaluate dynamic loads acting on artificial and normal knees during cycling. A force measurement System has been developed and was installed to evaluate the external loads on the pedals of a stationary bicycle. To analyze the data, different evaluation algorithms were programmed to calculate pedal force levels of the subjects during cycling.
