abstract: Examination of femoro-tibial torsion in patellar instability. A contribution to pathogenesis of recurrent and habitual dislocation of patella. In a CT-study are examined the angle of tibial torsion, femoral antetorsion, femoro-tibial rotation and tibio-femoral index as well as the habitual step angle by direct measurement in 40 patients with recurrent in habitual dislocation of the patella and in 10 normal persons. In comparison to the control group the femoral antetorsion and the femoro-tibial rotation in the pathological group were significantly increased. Results are discussed in regard of pathogenesis and operative treatment of patella dislocation.
