Conventional measurements of patella alta involve multiple measurements and are often not defined on cross-sectional imaging as related to radiographs. HYPOTHESIS Patellar articular overlap on sag...

The effect of quadriceps contraction during weight-bearing on four patellar height indices.
The effect of weight-bearing on the height of the patellar using four radiological indices was studied in 25 healthy men using lateral radiographs of the knee in 30 degrees of flexion non-weight-bearing and weight-bearing. The position of the patella was quantified using the Insall-Salvati, the modified Insall-Salvati, the Blackburne-Peel and the Caton indices. The contraction of the quadriceps...
