Abstract

Shrayash Singh, Sunil Kumar Duchania, Mukta Rani and Sunil Sharma

In this study the patella bones from both right and left sides were taken out of 60 individuals (30 males and 30 females). Bones were kept in 5% sodium hypochlorite solution for a week for maceration, and then dried and following measurements were taken: Maximum Length, Maximum Width, Maximum Thickness and Lateral Articular Facet Breadth in millimeters, and Weight in grams. Statistical analysis was done using SPSS 27.0. Descriptive statistics were obtained for each measurement. The North Indian population was compared with other populations. In the present study, the mean maximum height of the right side was 37.51 mm+3.17 SD for females and 41.54 mm+2.76 SD for males, while the mean of the left side was 37.91 mm+2.95 SD for females and 42.61 mm+2.97 SD for males. The sexual dimorphism was significant statistically, with a p-value <0.001 for both sides. The projected cut off value on the right side was 39.56 mm with a projected sensitivity of 86.7% and projected specificity of 73.3%, while on the left side cut off value was 38.76 mm with a projected sensitivity of 93.3% and projected specificity of 63.3%. The mean maximum breadth of right side was found to be 37.16 mm+3.07 SD for females and 42.99 mm+2.51 SD for males while the mean maximum breadth of left side was found to be 37.88 mm+2.95 SD for females and 42.61 mm+2.97 SD for males. The sexual dimorphism was found to be significant statistically with a p value <0.001 for both sides. The projected cut off value on right side was 40.48 mm with a projected sensitivity of 90.0% and projected specificity of 96.7% while on left side cut off value was 39.85 mm with a projected sensitivity of 90.0% and projected specificity of 83.3%. In the present study, measurements taken on patella bone showed higher mean values for males as compared with females (p<0.001).
