PATELLAR SHAPE, NOSE PATTERN AND FACET CONFIGURATION IN 200 NORTH
Author: Gaurav Agnihotri, Ramandeep Kaur, Gurdeep S Kalyan
Objective: Patella, the largest sesamoid bone is bestowed with morphology having anthropological and clinical significance. The paucity of available literature regarding the morphometric characteristics of this bone prompted the present study. Material and methods: A total of 200 patellae were obtained from male cadavers from medical colleges of Punjab, India. The morphometric parameters and position of median and secondary ridge was ascertained .The patellae were classified according to the shape patterns and facet configurations. Results: The most predominant shape pattern emerged to be Wiberg Type 2 with Normal Nose. A lateral facet prominence (Facet ratio 1.3) was observed for median ridge with considerable individual variation in the prominence of the secondary ridge (conspicuous in 12% cases). The secondary ridge was found to run obliquely in a generally longitudinal sense, being closer to median ridge proximally than distally. The patellar dimensions in general were smaller for North Indians compared to other populations. When right and left sides were compared, only maximum width was statistically significant (p<0.05). Conclusion: The study provides anthropometric data helpful for development of proper surgical techniques and prosthesis designs and addresses the significant omissions regarding the complex patellar form in standard anatomy textbooks.
Keywords: patellar dimensions, shape, facet prominence, variation.
