CORRELATION BETWEEN MORPHOMETRY OF PATELLAR LIGAMENT AND PATELLA-AN AID TO TOTAL KNEE ARTHROPLASTY

Abstract

Background: Patellar ligament is of surgical importance in procedures pertaining to total knee arthroplasty. It is extensively used as an autogenous graft for endoscopic anterior cruciate ligament reconstruction. Patellar ligament is the most preferred autograft owing to sufcient load to failure strength and stiffness. Purpose of the study: Dimensions of patella have been shown to be of anthropometric importance and is also used for personal identication as the bone is resistant to postmortem changes. There is paucity of literature on studies correlating the dimensions of patellar ligament and patella bone in Indian population. This study is the rst of its kind to provide data on the same. 53 prosected lower limbs were used to study the morphome Material and Methods: try of Patellar ligament and Patella using digital vernier calipers. The mean length, width and thickness values of Patellar ligament and bone were recorded. Pearson correlation coefcient was used to test the strength of association between the two variables. It was seen that there was negative correlation between Results: patella length and ligament length and thickness. There was positive correlation between patella length and ligament width. Patella width correlated positively with ligament length and ligament width but negatively with ligament thickness. Patella thickness correlated negatively with ligament length and thickness but positively with ligament width. This Conclusion- study will provide valuable anthropometric data and aid the orthopaedic surgeons performing knee surgeries.
