Kinematic and dynamic axial computerized tomography of the normal patellofemoral joint

Abstract

Fourteen normal volunteer with no history suggesting previous or current knee pathology underwent axial computerized tomographic examination of the patellofemoral joint. There were eleven men and three whose ages ranged from 10 to 46 years (av. 25 years). Axial images obtained 0°, 10°, 20°, 30°, 40°, and 60° of flexion both with and without contraction of the thigh muscles. Thus, twelve images were obtained for each individual. The CT scanner was foused at the midpatellar level prior to each image. Three measurements were made on twenty-four knees for each individual: congruence angle (CA), patellar tilt angle (PTA), and sulcus angle (SA).. Paired t-test, ANOVA, and Tukey's procedure were used for statical calculations. PTA increased slightly from 0° to 20° , and decreased slightly with more flexion (not significant, NS). The lower limit of PTA was usually 9° to 10° and not lower than 7° in any of knee positions. Muscle contraction increased PT A slightly at each degree of flexion (NS). CA was mean + 18.3° (SD: 20.8) at 0° which means that normal individuals may have cas as high as+39° at full extension. There was a gradual decrease in CAs with knee flexion. The mean values became negative between 20° and 60° flexion. Contraction of the thigh muscles caused lateralization of the patella except at 30° and 40° flexion. This Iateral pull was statistically significant at full extension (p<0.01) and at 1 0° flexion (p
