relation between the length of the patella and its tendon in adult Egyptian males

ABSTRACT

The length of the patella and the patellar tendon were measured form X-ray pictures of both knees of 100 adults Egyptian males as well as directly on cadaveric specimens, and the relations between them [Insall and Salvatti index] was calculated. 62% of subjects had an index value between 0.9 and 1.1, 2.5% had patella infera while 8% of the sample had patella alta which may cause extra stresses on the lateral part of the patello-femoral joint; in turn this may predispose to osteo-arthrotic changes in the knee which is a problem of considerable size among, Egyptian population
