Abstract

A recent suggestion by Izadpanah and Keönch-Fraknóy (1977) for the correction of the stressing of the knee-joint, is an epiarticular transpositary osteotomy with either a medial or lateral displacement of the condyle block, thus causing neither valgisation nor varisation. With the aid of compression tests on specimens and a photoelastic test, the authors try to prove the effect of this osteotomy. The tests give a false positive result. The submitted investigation deals with basics of correction osteotomies at the knee-joint. It shows that the effect of Izadpanah and Keönch-Fraknóy osteotomy is essentially slighter that the authors think and that furthermore, Maquet's subarticular rotation osteotomy is so far the best method available for centralisation of the force resultant in the joint.

Biomechanics

Biomechanics examines the generation of internal forces within the body and investigates the effects and control of forces that act on or are produced on tissues. Here are the latest discoveries.
