INTRODUCTION: The possible association between disorders of the femoro-patellar joint and geometrical anatomical variations in the patellar facet and femoral sulcus motivated us to conduct a morphometric study on the angle of the patellar facet and to correlate this with possible variation factors, such as: length,width at the midpoint of the femur, femur inclination angle, distance between condyles and depth of the patellar facet. Significance of the study in that obtained results would be useful for clinicians dealing with case of pathologic alterations in the sulcus angle and malignant of the patella femoral joint. AIMS AND OBJECTIVES: To measure the angle formed by the patellar facet in relation to the length of femur, the width at the midpoint of the femur, the femur inclination angle and many more. MATERIAL AND METHODS: The study was conducted in the department of Anatomy, Sardar Patel Medical College, Bikaner, Rajasthan on 200 dry human femur bones of both sides (including 95 right and 105 left) of unknown sex and age and also having no deformity. RESULT: Present study shows that range for patellar facet angle at the end point (PFAe) of the femoral sulcus from whole sample was observed 1160 to 1460 , for right side as 1170 to 1460 and for left side as 1160 to 1460 found. CONCLUSION: The results obtained as follows:- a) angle of the patellar facet: mean for start level of the patellar facet=142.80 ; mean for midpoint level =131.50 and mean for end level = 131.60 b) mean distance between condyles = 46.6mm c) mean depth of the patellar facet = 7.1 mm d) mean for Ficat and Bizou’s condylar depth index = 6.8 e) Inclination angle=125.50
