title: [Correction osteotomies of the knees. Factors altering the static angles on the radiographies through fault projection (author's transl)].
abstract: Comparing radiographies we have examined the degree in which the static angles of the knee are affected, because of a fault projection under the influence of some factors. We have found that an inwards or an outwards turn, even of a small degree (IQ), a bending or preexistent (pathological) anomalies, each alone or in combination, affected the right projection of the angles in a face radiography. Physiological knees possibly are presented like "varum" or "valgum" projectional. It is clear that the right position during the taking of the radiography is of a great significance in order to decide about the indication of osteotomy and to determine the degree of correction. We suggest as a criterion of the right radiographies the factor "patellacondylus".
