[Patellar height in patients with chondromalacia]

A radiogrametric assessment of the patellar height performed by three measurement methods, in the lateral views of radiograms of 136 patients with chondromalacia of the patella was aimed at the establishment of certain parameter values in the studied population and the assessment of the influence the altered patellofemoral ratio has upon the onset of the disease. The results of the study verified the remarkable advantages of the method by Insall and Salvati for the measurement of the patellar height and showed a significant involvement of patellofemoral incongruity in the development of chondromalacia, since in 15-16% of the cases the patella was not properly placed.
