title: The influence of mechanical loading on the knee-joint. Animal-experimental examinations.
abstract: A physiological maximal loading of the knee-joint of sheep is simulated by a 4-hour peak overloading of 24.5 N and a frequency of 42 impulses per minute. The reactions of articular cartilage, synovia and periarticular muscular tissue to the load were examined histologically, histochemically and biochemically. 20 hours after the loading we could observe a leucocytic influx into the joint and a metabolic hyperactivity in the examined tissue. The changes found during this acute phase are reversible as 180 days after peak overloading the parameters detected to be changed had returned to normal again.
