Die Beanspruchung des Kniegelenkes durch Kniebeugung als Präarthrose

Abstract

It cannot be concluded from occupational studies that kneeling and squatting or similar physical strains during work cause osteoarthrosis of the tibio-femural or patello-femoral joint. On the basis of methodical epidemiological and biomechanical considerations a causative correlation as described before cannot be expected. Nevertheless, in the occupational literature one can find some circumstantial evidence which may show whether mechanical functional stress influences the course of knee arthropathy (such as early patella osteophytes, osteoarthrosis of ankle joints) or not (early tibio-femural osteoarthrosis, lack of osteophytes in the elderly).
